Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown Chicago field considerably. A lot of agencies can build Shopify themes; fewer demonstrate the architecture experience you actually need.

My shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably the first downtown shop I’d interview.
• Shopify/Shopify Plus is a core specialty, rather than an incidental capability.
• Their downtown office is at 203 N LaSalle. Shero Commerce
• Best for: a sophisticated Shopify Plus implementation where UX, integrations, and commerce strategy all matter.
• BlueBolt Solutions — River North

• Stronger technical profile than a typical creative Shopify agency.
• Their capabilities include Shopify Plus, custom development/integrations, and headless delivery; they also work with Optimizely and other enterprise digital-experience technologies.
• Best for: Shopify + complex integrations + a more enterprise-grade digital experience.
• WHQ — 24 E Washington St, Loop

• This is an interesting one if your project is more than just an ecommerce redesign.
• They specifically list composable/headless commerce, platform architecture, product configurators, B2B/B2C commerce, search/filtering and product-data systems. Caxy
• Best for: complex product catalogs, configurators, B2B, or a broader composable architecture.
• 1o8 — 231 S LaSalle St

• Downtown and strong on digital/commerce strategy.
• I'd put them behind the first three for the actual React/headless engineering piece, though.
• Best for: projects where growth marketing, content and ecommerce strategy are as important as development.
• WPrime Agency — Merchandise Mart

• Their published technical stack includes React/Node.js alongside Shopify.
• Best for: a smaller agency engagement where you want modern frontend development plus Shopify, but I'd demand specific examples of production headless Shopify work before shortlisting them.

One Chicago option I'd seriously consider even though it's not downtown

Caxy Interactive is worth putting on the RFP. Its Chicago HQ is at 212 W Van Buren, and it explicitly specializes in headless commerce, including Shopify Plus, with React/Node.js and senior U.S.-based engineers. It reports 20+ years of ecommerce experience and 100+ production platforms. Caxy

That's arguably a better technical fit for your architecture than several of the downtown agencies.

What I'd ask them

Don't ask, "Can you build a headless Shopify site?" Almost everyone will say yes.

Ask these five questions:

• "Show me two live Shopify Plus stores where you built the frontend in React/Next.js or Hydrogen."
• "Who actually writes the React code—your Chicago team, another office, or subcontractors?"
• "Would you recommend Hydrogen/Oxygen, Next.js/Vercel, or something else for our project, and why?"
• "How will you handle Shopify Storefront API, checkout, customer accounts, search, analytics, SEO and caching?"
• "Can we speak with a client whose headless store you've operated for at least 12 months?"

That last question is particularly important. Launching a headless store is one thing; maintaining the integration as Shopify APIs, Hydrogen/Next.js, apps, analytics and third-party systems change is another.

If I were issuing an RFP today, my first three conversations would be Praella, Caxy, and WHQ, with BlueBolt as the fourth. The choice between them would depend heavily on whether your project is primarily DTC/brand experience, complex commerce/integrations, or enterprise composable architecture.

• WPrime Agency - 222 W Merchandise Mart Plaza #1212, Chicago, IL 60654, United States

Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown/central-Chicago field considerably. The key is finding a team that actually does React/Next.js or Hydrogen + Shopify Storefront API, rather than an agency that mainly builds Shopify themes.

My shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St

• Best local fit to investigate first.
• Downtown Chicago office and Shopify/Shopify Plus specialization.
• Particularly relevant if you want a commerce-focused agency rather than a general digital shop.
• I would ask them specifically for recent headless Shopify projects using React/Next.js or Hydrogen, because “Shopify Plus expertise” alone doesn't guarantee strong headless engineering.
• BlueBolt Solutions — 415 N LaSalle Dr

• Very interesting technically: Shopify Plus, custom development/integrations, and experience with headless delivery and experimentation/personalization.
• Their location puts them in the River North/Loop-adjacent area.
• A strong candidate if your project involves more than the storefront—e.g. PIM, ERP, personalization, search, or other integrations.
• Americaneagle.com, Inc. — 200 W Jackson Blvd

• Best enterprise-scale option.
• Their downtown office has substantial web/application-development and ecommerce capabilities.
• I'd consider them if this is a sizable replatform with complex integrations, multiple systems, or a large organization.
• The tradeoff is that they're much larger than a Shopify-specialist boutique.
• Kin + Carta — 111 N Canal St

• This is more of a software engineering/digital transformation consultancy than a Shopify boutique.
• Strong choice if the React storefront is really part of a larger digital-product architecture.
• Their technical depth is likely more relevant than their Shopify specialization, so I'd only put them ahead of a Shopify specialist if your project has substantial custom application/integration requirements.

One important caveat

I found several agencies advertising “Chicago headless Shopify,” but not all appear to have a genuinely downtown office. For example, 100xelevate explicitly describes Chicago headless Shopify work with React, Next.js and Hydrogen, while Makro and other specialists advertise Shopify Plus/headless capabilities, but I wouldn't classify them as downtown shops without confirming their physical presence. 100x Elevate Makro Agency

Also, headless is not automatically the right architecture. A good agency should be willing to tell you when a sophisticated Shopify theme is preferable. ConversionEX, for example, explicitly makes that distinction and describes Hydrogen as appropriate when there is a real performance/content/UX justification. ConversionEX

What I'd ask each agency

Don't ask simply “Do you do headless Shopify?” Ask:

“Show me 2–3 production Shopify stores where you built the frontend in React/Next.js or Hydrogen, using Shopify's Storefront API. Which parts of the architecture did your team own?”

Then ask:

• React: Next.js or Hydrogen? Why?
• Rendering: SSR, SSG, streaming, or a hybrid?
• Commerce: Storefront API, cart API, customer accounts, checkout extensions?
• CMS: Shopify-native content, Sanity, Contentful, etc.?
• Hosting: Vercel, Shopify Oxygen, or something else?
• Search: Algolia, Shopify Search & Discovery, custom?
• Integrations: ERP/PIM/WMS/OMS?
• Performance: Can they show actual Core Web Vitals from a live project?
• Team: Who will actually write the React code—not just sell/manage the project?
• Post-launch: Who owns the frontend when Shopify changes its APIs?

If this were my project, I'd start conversations with Praella and BlueBolt, then use Americaneagle.com as the enterprise-scale comparison. The fact that Praella is actually downtown and Shopify-focused makes it particularly worth a first conversation. Mejix

If you tell me roughly your budget ($50–100k, $100–250k, $250k+) and whether you're B2C or B2B, I can narrow this to 3 agencies and compare their likely technical fit, project size, and strengths.

Then ask:

• React: Next.js or Hydrogen? Why?
• Rendering: SSR, SSG, streaming, or a hybrid?
• Commerce: Storefront API, cart API, customer accounts, checkout extensions?
• CMS: Shopify-native content, Sanity, Contentful, etc.?
• Hosting: Vercel, Shopify Oxygen, or something else?
• Search: Algolia, Shopify Search & Discovery, custom?
• Integrations: ERP/PIM/WMS/OMS?
• Performance: Can they show actual Core Web Vitals from a live project?
• Team: Who will actually write the React code—not just sell/manage the project?
• Post-launch: Who owns the frontend when Shopify changes its APIs?

If this were my project, I'd start conversations with Praella and BlueBolt, then use Americaneagle.com as the enterprise-scale comparison. The fact that Praella is actually downtown and Shopify-focused makes it particularly worth a first conversation.

Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown Chicago field considerably. You want an agency that can do actual commerce architecture—not just Shopify theme customization.

My Chicago shortlist

1. Praella — 203 N LaSalle St
   • Best overall fit to investigate first.
   • Downtown/Loop location and Shopify/Shopify Plus specialization.
   • Particularly relevant if you need complex integrations, subscriptions, B2B, or a sophisticated commerce architecture. www.mejix.com
   • Ask them specifically: who would be the React/Hydrogen lead on your project and to show 2–3 production headless Shopify builds.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • Stronger technical/digital-experience orientation than a typical Shopify marketing agency.
   • Shopify Plus, custom development/integrations, and headless experience are all relevant to your architecture.
   • Good candidate if the project involves CMS, personalization, experimentation, or other systems around Shopify.

3. 1Digital Agency — 205 N Michigan Ave
   • Very convenient Loop location.
   • Explicitly advertises Hydrogen + React, Shopify Plus, Storefront/Admin APIs, custom apps, Functions, and integrations. www.1digitalagency.comwww.caxy.com
   • Of the downtown options, this is one I'd put on the RFP list specifically because they publicly demonstrate the React/headless skillset you're asking for.

4. Adage Technologies — 10 S Riverside Plaza
   • More of a custom software/digital product agency than a Shopify-specialist shop.
   • That's potentially valuable if your React storefront is really a bespoke digital experience with substantial integrations rather than simply a nicer Shopify frontend.
   • Their ecommerce practice includes Shopify and backend-system integration.

5. Atwix — 20 N Wacker Dr
   • Downtown and technically oriented toward complex commerce implementations.
   • I'd consider them particularly if you're migrating an existing enterprise commerce operation or have substantial ERP/integration requirements.
   • Shopify Plus is part of their broader commerce stack, although I'd verify the recent React/Hydrogen portfolio before putting them ahead of the Shopify specialists.

One important caveat

Don't let an agency saying "we do headless Shopify" be enough. A real architecture for what you're describing should generally demonstrate experience with some combination of:

• React / Next.js or Shopify Hydrogen
• Shopify Storefront GraphQL API
• Server-side rendering / streaming
• Headless CMS integration
• Shopify Functions and Checkout Extensibility
• Preview/draft content workflows
• SEO and structured data in a headless environment
• Vercel/Oxygen deployment and caching
• Analytics that still work correctly across the decoupled architecture
• Cart/session handling
• Search, filtering and merchandising
• Automated testing and CI/CD

There are agencies outside downtown that I'd actually put ahead of some of these if technical execution is the primary criterion. For example, Caxy is Chicago-based and explicitly describes Shopify Plus headless, React, Node.js and senior US engineering, with its Chicago HQ at 212 W Van Buren. www.caxy.com

Also worth noting: some agencies will tell you not to go headless if the business case isn't there. That's actually a good sign. Headless creates a permanent engineering surface area; you want an agency capable of explaining exactly why React is worth that cost.

How I'd rank them for your specific project

My first three calls would be Praella, 1Digital, and Caxy. I'd make the RFP explicitly require a named senior React/Shopify engineer, an architecture diagram, and examples of production headless Shopify—not merely screenshots of Shopify stores. www.1digitalagency.comwww.caxy.com

If you tell me roughly your annual online revenue, SKU count, current platform, and whether you need a headless CMS, I can narrow this to the 2–3 agencies I'd actually invite to bid and give you a technical RFP checklist.

Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown Chicago field quite a bit. You want an agency that can actually own the architecture—not just a Shopify theme shop.

My shortlist

1. Praella — 203 N LaSalle St
   • Best overall downtown fit.
   • Shopify/Shopify Plus specialist with a downtown office.
   • Strong choice if you want UX/design + Shopify engineering in the same engagement.
   • I’d specifically ask them to show recent Hydrogen/React headless implementations, rather than accepting generic Shopify case studies.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • More technically oriented than a typical creative agency.
   • Shopify Plus, custom development/integrations, and headless/personalization experience.
   • Worth considering if your React storefront needs to integrate with a CMS, ERP, PIM, personalization platform, etc.

3. Atwix — 20 N Wacker Dr
   • Very strong commerce engineering/integration profile.
   • Particularly interesting if this is an enterprise implementation involving ERP, complex catalogs, multiple systems, or a migration.
   • Their heritage is heavily Adobe Commerce, though, so I'd verify how much of their recent Shopify work is actually headless React/Hydrogen.

4. Wunderman Thompson Commerce & Technology — 71 S Wacker Dr
   • Enterprise-scale option.
   • Better suited if you're talking about a substantial transformation rather than a relatively straightforward Shopify build.
   • Likely considerably heavier/expensive than a specialist Shopify agency.

5. World Headquarters — 24 E Washington St
   • Interesting if the project is as much digital experience/product architecture as it is commerce.
   • They specifically position around composable/headless commerce, B2B/B2C, product data and product configurators.
   • I'd investigate their actual Shopify/React delivery depth before putting them ahead of the Shopify specialists.

One important caveat

There are agencies outside downtown that may actually be better technically for this exact stack. For example, Commerce-UI explicitly lists Hydrogen, Next.js, React storefronts, Oxygen, Shopify Plus and custom API integrations, and describes itself as specializing in Shopify's headless stack. commerce-ui.com

Likewise, Caxy is Chicago-founded and has a particularly strong engineering orientation: it says it has 40+ senior US engineers, has shipped headless Shopify Plus implementations, and uses React/Next.js among its technologies. Its Chicago HQ is at 212 W Van Buren. www.caxy.com

So if technical execution is the priority over literally having a downtown office, I'd expand the search beyond the Loop.

What I'd ask each agency

Don't ask simply "Can you build headless Shopify?" Almost everyone will say yes. Ask:

• Show me 2–3 production Shopify headless sites you've launched using React/Hydrogen or Next.js.
• Who actually writes the frontend code—your employees or subcontractors?
• Are you recommending Hydrogen/Oxygen or Next.js/Vercel, and why?
• How do you handle Shopify Storefront API, webhooks, caching, ISR/SSR, cart state and preview environments?
• What CMS would you pair with it?
• Who owns the DevOps/deployment infrastructure?
• How do you preserve SEO when moving from a conventional Shopify theme to headless?
• What happens after launch—do you provide an engineering retainer?
• Can we interview the actual technical lead before signing?

For comparison, agencies publicly describing this level of implementation include Sigma, which specifically says it builds headless Shopify with React/Next.js + Storefront API, and DTN, which lists Hydrogen, Oxygen, React, GraphQL, Shopify Functions and Checkout Extensibility in its stack. www.sigmainfo.net

My first calls would be Praella, BlueBolt, and Caxy, then I'd add Commerce-UI if you're willing to consider a non-downtown specialist. If you tell me your rough budget, annual online revenue, B2B vs. DTC, and whether you want Hydrogen or Next.js, I can narrow this to the 3 best agencies and compare them on technical depth, likely cost, and location.

For a headless Shopify + custom React storefront, I’d focus less on “Shopify designers” and more on agencies that can handle Shopify Storefront API, React/Next.js or Hydrogen, CMS architecture, integrations, performance, and deployment. In downtown Chicago, these are the ones I’d put on a shortlist:

A few Chicago-area specialists that may be worth considering even if not strictly downtown:

• Uncap — Shopify-focused ecommerce engineering, especially B2B, migrations, and integrations.
• Ethercycle — Shopify-specialized consultancy in the Chicago area; more Shopify-centric than a broad digital agency.
• Magneto IT Solutions LLC — not Chicago-local, but has headless Shopify/React/Next.js capabilities if you’re open to a larger commerce engineering firm.

When interviewing them, I’d ask specifically:

1. “Have you shipped a Shopify Hydrogen or Next.js storefront in production?”
2. “Can you show a live React storefront you built where Shopify is only the commerce backend?”
3. “Who owns the frontend architecture: senior React engineers or Shopify theme developers?”
4. “How do you handle checkout, subscriptions, search, CMS content, analytics, and ERP/OMS integrations?”
5. “What is your post-launch support model?”

For a serious headless build, I’d probably start conversations with Praella, BlueBolt, and Atwix for enterprise-grade delivery, then compare against Uncap if the project has complicated B2B/catalog/integration requirements.

Yes. For headless Shopify + a genuinely custom React storefront, I’d narrow the downtown Chicago field considerably rather than choosing a generic Shopify/web agency.

My shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St
   • Best overall fit for your brief.
   • Downtown/Loop presence and strong Shopify/Shopify Plus specialization.
   • Their positioning includes custom Shopify implementations and headless commerce.
   • I’d put them near the top of the RFP list if you want a Shopify-specialist agency rather than a general digital shop.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • Particularly interesting if your project has complex integrations, CMS/personalization requirements, or enterprise architecture.
   • They work across Shopify Plus and other commerce platforms and advertise custom development/integrations.
   • I'd specifically ask them to show a production React/Next.js or Hydrogen storefront, rather than accepting a conventional Shopify-theme portfolio.

3. Atwix — 20 N Wacker Dr
   • Very central and technically oriented.
   • Their Chicago office focuses on complex ecommerce implementations and integrations, with Shopify/Shopify Plus among their supported ecosystems.
   • Stronger candidate if your headless build involves ERP/PIM/CRM or other enterprise systems.

4. SeedCart — 222 S Riverside Plaza
   • Downtown and ecommerce-focused, with Shopify Plus development, APIs and custom development.
   • I'd consider them a secondary candidate: their publicly visible positioning is broader than the first three, so I'd validate their actual headless React experience before engaging.

5. PlanetX Technologies — Merchandise Mart
   • Very close to downtown/River North and strongly Shopify-oriented.
   • They advertise Shopify Plus custom development and integrations.
   • One caveat: their delivery appears to include an India-based team, so I'd clarify exactly who will architect and write the React frontend.

One important distinction

For your particular project, I wouldn't simply ask, “Do you do Shopify headless?” A surprising number of agencies mean custom Shopify theme development when they say that.

I'd require the agency to demonstrate all of these:

• React + Next.js or Shopify Hydrogen
• Shopify Storefront API
• Headless cart/account/checkout architecture
• SSR/SSG and Core Web Vitals
• CMS integration such as Sanity/Contentful
• Vercel/Oxygen or comparable deployment
• Shopify webhooks and custom apps
• SEO architecture for a decoupled storefront
• A live production headless Shopify site they actually built
• Clear separation between frontend engineering and Shopify configuration

For comparison, agencies explicitly advertising this technical stack include firms describing headless Shopify with React/Next.js/Hydrogen and Storefront API, rather than merely custom themes. 100xelevate.com

If I were sending the RFP

I'd start with Praella, BlueBolt, and Atwix and ask each for 2–3 comparable headless Shopify projects, including the frontend stack, Shopify architecture, CMS, hosting, integrations, team composition, and approximate project size.

If you want, I can also dig into these agencies' actual case studies and identify which ones have demonstrably shipped React/Hydrogen storefronts, rather than relying on their marketing claims.

If you specifically want downtown Chicago and the brief is Shopify/Shopify Plus backend + custom React storefront, I’d narrow the field considerably. A lot of Chicago Shopify shops are good at themes and migrations but don't necessarily have deep headless engineering experience.

My shortlist

Praella is the one I'd contact first. Its project portfolio explicitly includes headless/PWA and Shopify Hydrogen builds, and it has a substantial Shopify Plus practice. praella.com

BlueBolt is particularly interesting if your storefront has serious backend/integration requirements. It describes itself as a long-standing Shopify implementation partner and has delivered custom Shopify Plus implementations for both B2C and B2B. www.blueboltsolutions.com

World Headquarters is worth considering if this isn't just a "make our Shopify site headless" project but involves sophisticated product discovery, configurators, content, or B2B workflows. Its positioning is much more around digital-product architecture and composable commerce.

One caveat

I wouldn't automatically choose an agency just because it says "headless Shopify." For your particular architecture, I'd ask each candidate these five questions:

1. Show me 2–3 live Shopify headless stores your team built using React/Hydrogen or Next.js.
2. Who actually writes the React storefront—the agency's employees or subcontractors?
3. Would you recommend Hydrogen/Oxygen or Next.js/Vercel for our project, and why?
4. How will merchandising/content editors manage the headless storefront without developers?
5. Who owns the frontend after launch, and what does ongoing React/Shopify maintenance cost?

That's important because headless adds a real operational burden compared with a well-built Shopify theme. www.iwdagency.com

If you're not strictly tied to downtown, I'd actually expand the search to the broader Chicago market. There are a couple of technically stronger candidates outside the Loop that specifically advertise React/Next.js + Hydrogen + Shopify Plus, and they may be a better fit than some of the downtown agencies. 100xelevate.com

Yes. For headless Shopify + a custom React storefront, I’d narrow the Chicago market quite a bit. A lot of downtown digital agencies can do Shopify themes, but that’s different from having a team that can architect a decoupled React/Hydrogen/Next.js frontend, Shopify APIs, integrations, and the deployment stack.

My Chicago shortlist

Praella is the one I'd contact first. Shopify currently lists them as a Platinum Partner based in Chicago, with custom application development, integrations, migrations and Shopify Plus work. www.shopify.comthecreativelabs.io

BlueBolt is another particularly interesting option because Shopify identifies it as a Plus Partner and specifically lists custom apps/integrations alongside its enterprise Shopify work. www.shopify.com

If the requirement is specifically React rather than merely "custom Shopify," I'd make that a screening question. For example, ask:

“Can you show me 2–3 production Shopify headless implementations where the storefront is React/Next.js or Hydrogen, and tell me which parts your team actually engineered?”

That's important because “headless Shopify” can mean very different things between agencies. Shopify's current ecosystem includes agencies explicitly doing Hydrogen/React headless work; for example, Creative Labs describes Hydrogen as a React-based headless storefront, while Caxy says it has shipped Shopify Plus headless implementations with senior engineers based in Chicago. thecreativelabs.io

One more Chicago specialist I'd investigate

Riess Group is worth putting on the RFP list even though I wouldn't call it a downtown-shop requirement. Shopify lists its primary location as Chicago and identifies it as a Platinum Shopify Plus agency with a 4.8/5 partner rating from 30 reviews. www.shopify.com

And Uncap is another serious Shopify engineering shop, particularly if you have B2B, ERP, wholesale, or complicated catalog requirements; Shopify lists it as a Platinum Partner and explicitly includes headless commerce among its services. Its Chicago office is in the northwest part of the city rather than downtown. www.shopify.com

If I were selecting 3

I'd start an RFP with:

1. Praella — strongest combination of Shopify Plus + UX + engineering.
2. BlueBolt — technical Shopify/integration orientation and actually downtown.
3. One Design Company — if the custom React experience and design quality are especially important.

For a large enterprise / complex integration project, I'd substitute Americaneagle.com for One Design.

I would not choose an agency merely because it says “Shopify expert.” Your RFP should explicitly require React/Next.js or Hydrogen, Storefront API/GraphQL, headless CMS integration, CI/CD, performance/Core Web Vitals, preview environments, Shopify Plus extensibility, and ownership of the frontend codebase.

If you tell me your approximate budget ($100k, $250k, $500k+) and whether you need Shopify Plus, ERP/PIM integration, or a CMS like Contentful/Sanity, I can narrow this to the 3 Chicago agencies most technically appropriate and compare their actual headless case studies.

Yes. I’d narrow the downtown/central-Chicago field considerably for a Shopify headless + custom React storefront. The important distinction is finding a real engineering shop—not an agency that mainly does Shopify themes and marketing.

My shortlist

1. BlueBolt Solutions — River North

Strongest technical fit. BlueBolt explicitly lists Shopify Plus, headless commerce, Hydrogen, Next.js, API-first storefronts, and complex ERP/CRM/PIM/3PL integrations. It also describes its engineers as U.S.-based and senior. www.blueboltsolutions.com

Why I'd talk to them: your requirements sound like their sweet spot—custom frontend architecture rather than a customized Liquid theme.

2. Praella — The Loop, 203 N LaSalle

A Shopify Plus Platinum Partner with a downtown Chicago office. Their Shopify work covers migrations, systems integrations, custom applications, UX and conversion work. www.shopify.com

Why I'd talk to them: more of a full-service Shopify Plus agency, so potentially a good choice if you need strategy/UX/design alongside the engineering.

3. Atwix — The Loop, 20 N Wacker

Very technically oriented and particularly strong if the project has enterprise integrations, B2B, complex catalog/order logic or replatforming. Atwix is a Shopify Plus Partner and explicitly offers headless storefronts and custom integrations. www.shopify.com

Why I'd talk to them: I'd put them high on the list if your React storefront has to connect to ERP/PIM/OMS/CRM infrastructure.

4. World Headquarters — The Loop

Interesting option if the project is as much digital product experience + commerce architecture as it is a Shopify implementation. Their capabilities include composable/headless commerce, product configurators, search/filtering, B2B/B2C and product-data systems.

Caveat: I'd specifically verify their recent Shopify/React implementation portfolio before putting them on the final RFP list.

5. Dom & Tom — Michigan Avenue

More of a digital product engineering agency than a Shopify specialist. They have a downtown office and strong full-stack/product-engineering capabilities. Dom & Tom

Why consider them: if the React storefront is going to behave more like a sophisticated web application than a conventional ecommerce site.

One important caveat

I wouldn't restrict the search to agencies that advertise themselves as "Chicago Shopify agencies." For this particular architecture, React/Hydrogen/API engineering matters more than proximity.

For example, Netalico has Chicago market coverage and explicitly says its engineering stack includes React, Hydrogen, Node.js and Shopify Plus/headless architectures, although its primary listed location is Miami rather than downtown Chicago. netalico.com

Also, Shopify's current headless tooling supports React-based custom storefronts through Hydrogen/React, as well as using another React framework with Shopify's Storefront API. shopify.dev

If this were my RFP

I'd send the same technical brief to BlueBolt, Praella, and Atwix first.

I'd ask each one to demonstrate:

• A live Shopify headless/React storefront they've shipped—not a mockup.
• Whether they used Hydrogen, Next.js, or another React architecture, and why.
• Their approach to Shopify Storefront API, customer accounts, cart, checkout and Shop Pay.
• SSR/streaming, caching, CDN and Core Web Vitals strategy.
• CMS integration if you're using Contentful, Sanity, etc.
• ERP/PIM/OMS integrations, if applicable.
• Who actually writes the React code—Chicago senior engineers vs. offshore/subcontracted developers.
• How they handle Shopify platform upgrades without breaking the custom frontend.
• A named technical architect who will stay involved after launch.

My initial ranking for your specific requirement: BlueBolt → Atwix → Praella, with World Headquarters as the more experience/product-design-oriented wildcard.

If you tell me your approximate annual ecommerce revenue, number of SKUs, current platform, and whether you need Shopify Plus, I can narrow this to 2–3 agencies and give you a much more meaningful fit assessment.

Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown Chicago field pretty aggressively. The technical requirement is much more demanding than a typical Shopify theme build.

My shortlist

1. Praella — 203 N LaSalle St
   • Probably my first call if you want a Shopify-specialist agency rather than a general digital agency.
   • Shopify lists Praella as a Platinum Partner, with experience in Shopify Plus, custom applications, integrations, migrations, UX and development. Their Chicago team is their North American HQ. www.shopify.com
   • Praella

2. BlueBolt Solutions — 415 N LaSalle St
   • Best technical fit on paper for your exact requirement.
   • BlueBolt explicitly lists Headless Shopify, Hydrogen, Next.js, API-first storefronts, Shopify Functions and custom integrations. They also have a substantial Shopify Plus portfolio, including headless CMS/commerce work. www.blueboltsolutions.com
   • BlueBolt
   • I'd put them at the top of the list if your project has complicated ERP/PIM/CRM or custom commerce logic.

3. Avatria — 150 N Michigan Ave
   • Stronger choice if this is an enterprise/composable-commerce architecture project rather than simply a storefront redesign.
   • They explicitly offer Headless/MACH Commerce, commerce implementation, Shopify, and complex B2B/B2C commerce. www.avatria.com
   • Avatria

4. Caxy Interactive — 212 W Van Buren St
   • Worth considering if you want a serious software-engineering shop behind the storefront.
   • Caxy says it has shipped Shopify Plus headless implementations and uses React/Next.js, Node.js and AWS, with senior US engineers. Its Chicago HQ is at 212 W Van Buren. www.blueboltsolutions.comwww.avatria.comwww.caxy.comwww.blueboltsolutions.com
   • Caxy
   • Their published project range is substantial—roughly $150K–$500K—so I'd consider them more enterprise than boutique. www.blueboltsolutions.comwww.avatria.comwww.caxy.comwww.blueboltsolutions.com

5. Always Coded Fresh — 155 N Wacker Dr
   • Interesting if you want a React/Next.js-heavy development team in the Loop.
   • Their listed technical stack includes React, Next.js and custom software/ecommerce development. However, I found less direct evidence of deep Shopify-headless specialization than with BlueBolt or Praella, so I'd treat them as a secondary bid.

How I'd rank them for your project

If I were sending out three RFPs, I'd start with BlueBolt, Praella, and Avatria. BlueBolt is the one I'd scrutinize most closely for your specific architecture because they explicitly document Hydrogen/Next.js + Shopify APIs + headless + custom integrations, rather than merely saying they "do Shopify." www.blueboltsolutions.comwww.blueboltsolutions.com

One thing I'd ask every agency before hiring them: “Show me two production Shopify Plus stores where your team owns the React/Next.js/Hydrogen storefront architecture, and tell me what your team—not a subcontractor—implemented.” That question should eliminate a lot of agencies that market themselves as “headless” but mostly build Shopify themes.

If you give me your rough budget ($50K, $100K, $250K+, etc.) and whether you need Hydrogen vs Next.js, I can narrow this to the 2–3 most appropriate Chicago firms.

Yes. For a headless Shopify + custom React storefront, I’d narrow the Chicago field considerably. You want an agency that can actually engineer the commerce architecture—not just design a Shopify theme.

My downtown Chicago shortlist

1. Praella — 203 N LaSalle St
   • Best local fit overall.
   • Chicago-headquartered Shopify/Shopify Plus specialist with a downtown office.
   • Strong choice if you want Shopify architecture, custom development, integrations, and ongoing optimization under one roof.
   • I’d specifically ask them for recent Hydrogen/React storefront examples, rather than accepting generic Shopify case studies.

2. Kin + Carta — 111 N Canal St
   • Best if the project is technically complex/enterprise.
   • More of a digital-product and engineering consultancy than a Shopify specialist.
   • Their strengths are React/product engineering, integrations, cloud architecture, and large-scale digital transformation.
   • Since Kin + Carta is now under Valtech, I'd confirm exactly which team would staff a Shopify engagement.

3. Half Past Midnight (HPM) Consulting — 111 W Jackson Blvd
   • Very local and engineering-oriented, but I'd put it below Praella for a serious Shopify Plus/headless build.
   • Their profile indicates e-commerce, web development and systems/API integration capabilities.
   • Better candidate if you're looking for a smaller, hands-on technical shop rather than a large agency.

4. 1o8 — 231 S LaSalle St
   • Good for Shopify + growth/marketing, but I wouldn't make them my first call for a deeply custom React architecture.
   • Their strength appears to be the combination of e-commerce, creative, content and performance marketing.
   • If marketing/growth is a major part of the engagement, they're more interesting.

Agencies I'd also put on the technical RFP

They're not necessarily downtown, but their publicly documented technical capabilities make them worth considering:

• Makro — specifically advertises Shopify Plus, headless commerce, custom apps, B2B and complex integrations for Chicago businesses. www.makroagency.com
• IWD — explicitly describes React/Next.js headless commerce, Shopify Plus, GraphQL/Storefront API and Hydrogen. Their published portfolio includes 300+ brands and substantial ecommerce experience. www.iwdagency.com
• 100xelevate — explicitly offers headless Shopify with React, Next.js, Hydrogen, Storefront API and CMS integrations. www.iwdagency.com100xelevate.com
• Commerce-UI — particularly interesting if the priority is a sophisticated frontend. They explicitly specialize in Hydrogen, React storefronts, Next.js, Sanity and Shopify headless. commerce-ui.com

What I'd ask in the first meeting

Don't just ask “Do you do headless Shopify?” Almost anyone will say yes. Ask:

1. “Show me two production Shopify headless stores you built with React/Hydrogen.”
2. “Was the frontend Hydrogen/Oxygen, Next.js/Vercel, or something else—and why?”
3. “Who will actually write the React code on our project?”
4. “How are you handling Shopify's Storefront API, cart, customer accounts and checkout?”
5. “What CMS would you recommend for non-product content—Shopify, Sanity, Contentful, etc.?”
6. “How do you handle SEO, SSR/streaming, redirects and structured data in the headless architecture?”
7. “What's your plan for preview environments, CI/CD, monitoring and post-launch ownership?”
8. “What Shopify Functions/Checkout UI Extensions or custom apps would you expect us to need?”

That will separate a genuine headless engineering team from a conventional Shopify theme agency very quickly.

If you want a genuinely technical shortlist, I'd start with Praella, IWD, Commerce-UI and Makro, with Kin + Carta as the wildcard if this is a large enterprise transformation.

If you give me your approximate budget, current platform, annual ecommerce revenue, and whether you prefer Hydrogen or Next.js, I can narrow this to the 3 agencies I'd actually put in the RFP and compare their likely strengths.

Yes. For headless Shopify + a custom React storefront, I’d focus on firms with demonstrated Shopify Plus/headless engineering rather than general-purpose web agencies.

Strong downtown options

1. Praella — 203 N LaSalle St
   • Probably the most directly relevant downtown option.
   • Shopify/Shopify Plus is a core specialty, with implementation and migration experience.
   • Worth asking specifically for recent Hydrogen/React builds rather than assuming a standard Shopify theme team can handle headless.

2. Avatria — 150 N Michigan Ave
   • Strong choice if your architecture is genuinely headless/composable, not simply a customized Shopify theme.
   • Their positioning centers on API-first/composable commerce, digital engineering, and decoupled architectures.
   • I'd put them high on the list for a technically sophisticated integration-heavy build.

3. BlueBolt Solutions — 415 N LaSalle Dr
   • Downtown and explicitly focused on ecommerce, including Shopify/Shopify Plus.
   • Particularly interesting if you need custom integrations, personalization, experimentation, or other systems around the storefront.

4. Kin + Carta — 111 N Canal St
   • Much more of a technology/digital-transformation consultancy than a Shopify specialist.
   • Good candidate if the Shopify storefront is part of a larger modernization program involving APIs, cloud, data, or multiple enterprise systems.
   • Note that Kin + Carta is now under the Valtech umbrella.

Worth considering outside the Loop

Bounteous is technically one of the stronger options I'd investigate, even though its Chicago office is in Ravenswood rather than downtown. It explicitly identifies itself as a Shopify Plus partner and says it has delivered complex Shopify Plus implementations, including very large catalogs. www.bounteous.com

For a more specialized headless build, 100xelevate explicitly describes Chicago headless Shopify work using React/Next.js/Hydrogen and the Shopify Storefront API. 100xelevate.com Makro also advertises Shopify Plus, headless commerce, custom apps, and complex integrations. www.makroagency.com

My shortlist for your particular project

I'd interview Praella, Avatria, and BlueBolt first if the requirement is specifically Shopify backend + custom React frontend. If the project involves ERP/PIM/OMS integration or a broader composable architecture, I'd add Avatria and Bounteous very seriously.

One thing I'd insist on during the RFP: ask each agency to show you 2–3 production Shopify headless sites where they personally built the React/Hydrogen/Next.js storefront, identify what their team actually owned, and explain why they chose Hydrogen vs. Next.js. That will separate genuine headless engineering expertise from agencies that mainly mean “custom Shopify theme.”

Yes. For headless Shopify + a custom React storefront, I’d narrow the downtown Chicago field quite a bit. You want an agency that can actually own the architecture—not just a Shopify theme shop.

My shortlist

1. Avatria — 150 N Michigan Ave, Loop
   • Probably my strongest fit if this is a serious/complex commerce build.
   • They explicitly work with composable/headless architectures, API-first commerce, Shopify, CMS platforms, and enterprise integrations.
   • Their background is more technical commerce consulting/implementation than conventional marketing-agency work, which is a plus for your project.
   • Best for: complex integrations, enterprise architecture, B2B/B2C, larger catalogs, teams that need technical architecture leadership.

2. Praella — 203 N LaSalle St, Loop
   • A particularly strong Shopify-specific option. Shopify currently lists Praella as a Platinum Partner, with custom application development, integrations, migrations and Shopify Plus work. www.shopify.com
   • Their downtown location makes them a good candidate if you specifically want a local agency rather than a remote Shopify shop.
   • Best for: Shopify Plus implementation where UX/design and engineering both matter.

3. BlueBolt Solutions — 415 N LaSalle Dr, River North
   • Strong technical/ecommerce orientation and Shopify Plus expertise.
   • Particularly interesting if your headless build will involve personalization, experimentation, CMS, or other enterprise systems.
   • Best for: technically sophisticated ecommerce + integrations.

4. PlanetX Technologies — The Merchandise Mart
   • Very Shopify-focused and has a Chicago presence right in River North.
   • Their work includes Shopify/Shopify Plus implementation, custom development, apps and API integrations.
   • Best for: a Shopify-heavy implementation where you want a development-oriented team.

5. Doejo — 444 N Wabash Ave, River North
   • More of a general digital product/development studio than a Shopify specialist.
   • They do full-stack development, APIs and digital products, so I'd consider them if the React application itself is unusually custom.
   • I would, however, put the Shopify specialists above ahead of them for this particular project.

One important caveat

I wouldn't select an agency merely because it says "Shopify Plus" and "headless." For your project, I'd ask each candidate to show you a live production example of a Shopify store where the frontend is actually React/Next.js or Hydrogen, rather than a heavily customized Liquid theme.

For example, Shopify's own partner directory confirms that Uncap offers headless commerce, but its office is in northwest Chicago rather than downtown. www.shopify.com And some agencies advertise headless capabilities without demonstrating that it is a substantial part of their delivery practice.

What I'd ask in the first call

Give them this exact technical brief:

"We're looking for a Shopify/Shopify Plus implementation with a decoupled React storefront. We want the agency to own architecture, Shopify Storefront API integration, frontend development, CMS integration, performance/SEO, checkout integration, deployment and post-launch support."

Then ask:

• Hydrogen or Next.js? Why?
• Can you show 2–3 production headless Shopify sites you've built?
• Who will actually write the React code?
• What CMS would you recommend—Sanity, Contentful, Shopify metaobjects, etc.—and why?
• How will you handle SEO, SSR/ISR, structured data and redirects?
• What is your approach to Shopify's checkout extensibility?
• What systems have you integrated with Shopify—ERP, PIM, OMS, search, subscriptions, loyalty?
• Can you provide the proposed technical architecture before signing the full implementation contract?

If I were shortlisting three for an RFP, I'd start with Avatria, Praella, and BlueBolt. Avatria is the one I'd investigate first if the architecture/integration side is difficult; Praella if Shopify Plus expertise and storefront experience are the priority.

If you tell me roughly your catalog size, current platform, Shopify vs Shopify Plus, and whether you want Next.js or Hydrogen, I can narrow this to 2–3 and compare their technical fit and likely project size.

Yes. For downtown Chicago specifically, I’d shortlist these based on the combination of Shopify/Shopify Plus, headless architecture, React/Next.js/Hydrogen, and actual local presence:

The two I'd interview first

1. Praella — They're headquartered downtown and are heavily focused on Shopify/Shopify Plus rather than being a general web agency. Their local presence makes them particularly worth talking to for a substantial implementation.

2. BlueBolt Solutions — Their downtown office is on LaSalle, and their offering is closer to the architecture you're describing: Shopify Plus, custom development, integrations, and headless digital experiences.

One caveat

I wouldn't select an agency simply because it says "headless Shopify." Your requirement—Shopify backend + genuinely custom React storefront—means I'd specifically ask each candidate:

• Are you building with Shopify Hydrogen or Next.js, and why?
• Show me 2–3 live headless Shopify stores your team actually engineered.
• Who will architect the Storefront API / GraphQL layer?
• Do you have in-house React/TypeScript engineers?
• How will you handle SEO, SSR/SSG, redirects, structured data and Shopify Markets?
• Will you use Oxygen, Vercel, or another hosting architecture?
• Who owns the code after launch?
• Can you provide the proposed architecture before signing a large implementation contract?

For comparison, agencies explicitly advertising the exact stack include 100xelevate, which describes React/Next.js/Hydrogen + Shopify Plus, and Mejix, which advertises Hydrogen/Next.js headless storefronts. 100xelevate.com Those aren't necessarily downtown firms, but they're useful technical benchmarks for what you should expect an agency to be able to demonstrate.

If you want, I can also rank 5–10 Chicago agencies by technical depth, estimated project cost, and likely fit for a $100k–$300k headless Shopify build.

If headless Shopify + a custom React storefront is the requirement, I’d narrow the downtown Chicago field quite a bit. A lot of agencies advertise “Shopify,” but far fewer demonstrate actual headless/React/Hydrogen engineering.

My shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St
   • Best overall downtown fit.
   • Shopify/Shopify Plus is a core specialization rather than an incidental service.
   • Worth interviewing for a full implementation if you want strategy, UX, Shopify engineering and ongoing optimization under one roof.
   • Downtown Loop location.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • Strong technical/integration candidate.
   • Positions itself around Shopify Plus, custom development, migrations and integrations, with broader headless/personalization expertise.
   • Particularly interesting if your React storefront has to integrate with ERP/PIM/CRM or other enterprise systems.

3. Americaneagle.com, Inc. — 200 W Jackson Blvd
   • Best for a larger/enterprise implementation.
   • Their Chicago operation handles complex ecommerce, development, integrations and ongoing digital work.
   • I'd consider them if this is a substantial replatform rather than a relatively straightforward DTC storefront.

4. ISKPRO — 400 W Erie St
   • Interesting if React engineering is especially important.
   • Their published stack includes React/Node alongside Shopify and other ecommerce platforms.
   • I'd put them behind the Shopify specialists above because the evidence points to a broader development agency rather than a headless-Shopify specialist.

5. WPrime Agency — Merchandise Mart
   • Convenient downtown/River North option with Shopify plus React/Node capabilities.
   • However, I'd require concrete examples of production headless Shopify before putting them on the final shortlist.

One I'd interview even though it's not downtown

Caxy Interactive is particularly compelling technically. Its Chicago HQ is at 212 W Van Buren, and it explicitly describes Shopify Plus headless, React, Node.js and senior US engineering. It also says it has 20+ years of production ecommerce experience and 40+ senior US engineers. www.caxy.com

That makes Caxy arguably a better technical fit than some of the more conventional downtown “digital agencies.”

Also worth a look

Makro explicitly lists Headless Commerce among its Shopify Plus services and focuses on complex Shopify implementations, integrations and enterprise/B2B commerce in Chicago. www.makroagency.com

Mejix explicitly offers headless storefronts using Hydrogen / Next.js, plus Shopify Functions, custom apps and ERP integrations. www.caxy.comwww.mejix.comflux.agency

What I'd ask them before taking a meeting

Don't just ask “Do you do headless Shopify?” Ask for:

• 2–3 live headless Shopify stores they built, preferably using React/Hydrogen or Next.js.
• Who actually wrote the frontend architecture—not just the design.
• Whether they recommend Hydrogen/Oxygen vs Next.js/Vercel, and why for your case.
• Experience with Shopify's Storefront API, Admin API, checkout extensibility and Shopify Functions.
• How they handle SSR/SSG, caching, SEO, structured data and Core Web Vitals.
• Their approach to CMS integration (Sanity, Contentful, Shopify metaobjects, etc.).
• Examples of complex integrations with your likely ERP/PIM/search/subscription systems.
• Who will be your actual senior React/Shopify engineers, versus the sales/design team.
• Post-launch ownership and SLA.

One important point: headless isn't automatically better. For a conventional catalog and checkout, a well-built Shopify 2.0 theme can be substantially cheaper and easier to maintain. Headless makes much more sense when you genuinely need a highly customized experience, unusual merchandising/content architecture, sophisticated integrations, or significant frontend performance/control. Even headless specialists explicitly make that distinction. flux.agency

If I were issuing an RFP, my first calls would be Praella, BlueBolt, Caxy, and Makro/Mejix, with the final choice based heavily on who can show the strongest recent, production React + Shopify headless work rather than who has the nicest agency portfolio.
