I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer serving clients on different CMSs, I’d optimize for “works independently of the client’s CMS” rather than picking a builder that is excellent at one CMS.

My pick: Unbounce

unbounce.com is probably the best fit for your situation.

Why:

  • CMS-agnostic: You build the landing page in Unbounce and can publish it independently, rather than learning each client's CMS.
  • WordPress support: It has an official WordPress plugin, including publishing without requiring you to log into WordPress every time. Unbounce Unbounce
  • Multiple clients: Unbounce has dedicated client environments, permissions, separate domains, and client access within an account. Unbounce Documentation Unbounce Documentation
  • Works with marketing stacks: Salesforce, HubSpot, Zapier, webhooks, Mailchimp, etc. Unbounce Unbounce
  • Actually built for landing pages: A/B testing, Smart Traffic, dynamic text, popups/sticky bars, conversion reporting, etc.
  • Easy to hand off: The client doesn't necessarily need to give you administrator access to their main website.

For a freelancer, that last point is particularly valuable: you can treat the landing page as a separate deliverable even when the client is using WordPress, Shopify, Webflow, a custom site, HubSpot, or something else.

How I'd rank them for your use case
PlatformFlexibility across client CMSsDesign freedomCRO/testingFreelancer/client management
Unbounce⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Instapage⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Webflow⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Leadpages⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Framer⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Instapage is the strongest alternative if you're doing lots of paid-ad campaigns for larger clients. It has 120+ integrations, extensive personalization/testing features, and WordPress publishing. Instapage Instapage Help Center

Webflow is better if what you're really selling is complete website/marketing-site design, rather than standalone conversion landing pages. It gives you substantially more design/CMS control, but you're then dealing with the client's Webflow setup rather than having a CMS-independent landing-page layer.

The setup I'd use as a freelancer

I'd actually structure your service like this:

Client CMS → landing page platform → CRM/email/analytics

So, for example:

WordPress / Shopify / Webflow / custom site

Unbounce

HubSpot / Salesforce / Mailchimp / Zapier / webhook

That lets you keep essentially the same production workflow regardless of what CMS the client happens to use.

If you tell me the 3–5 CMSs you encounter most often (e.g. WordPress, Webflow, Shopify, HubSpot, Squarespace), I can tell you which platform gives you the least friction across that exact mix.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer working across different client CMSs, I’d prioritize portability, custom-code access, integrations, and how easily you can hand a page back to the client.

My pick: Webflow

webflow.com is probably the most flexible general-purpose choice.

  • CMS flexibility: Its CMS has APIs, custom fields/reference fields, and integrations, so you can build more than just a static landing page. Webflow Webflow
  • Custom code: You can inject HTML/CSS/JS and dynamically use CMS fields in embeds. Webflow Help Center Webflow Help Center
  • Client handoff: You can export HTML/CSS/JS/assets and host them elsewhere on eligible Workspace plans. However, CMS functionality, forms, ecommerce, etc. don't survive a normal code export, so this isn't completely platform-independent. Webflow Help Center
  • Developer-friendly: Webflow also supports exporting components into React codebases via DevLink, which is useful when clients have more custom stacks. Webflow Help Center
But there's an important distinction

If by "landing page platform" you mean a tool you can use alongside whatever CMS the client already has, rather than replacing their CMS:

Unbounce may actually be better. unbounce.com

It's designed specifically for this freelancer/agency workflow: separate client accounts, permissions, domains, reusable pages, A/B testing, and integrations with CRMs/marketing tools. It also supports webhooks and 60+ integrations through Zapier, making it relatively CMS-agnostic. Unbounce Documentation Unbounce Unbounce

I'd think about it this way:

Your situationBest fit
Build complete marketing sites + landing pagesWebflow
Landing pages that need to coexist with WordPress/HubSpot/etc.Unbounce
Heavy paid-ads / CRO / A-B testingUnbounce
Maximum visual/design freedomWebflow
Client may eventually want the site moved elsewhereWebflow, with export limitations
Lots of separate clients to manageUnbounce
Highly custom/developer-oriented buildsWebflow

For a freelancer, I'd probably use both: Webflow as the "build almost anything" tool, and Unbounce when the client's primary requirement is campaign landing pages + conversion optimization rather than owning the whole website.

If you tell me which CMSs you commonly encounter (e.g. WordPress, Shopify, HubSpot, Webflow, Wix, Squarespace, custom React), I can narrow this down to the best 1–2 tools for your exact workflow.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you're a freelancer working across different client CMS setups, I'd prioritize portability + custom code + integrations over a platform that's merely good at making landing pages.

My pick: Webflow

Webflow is probably the most flexible all-around freelancer choice.

Why:

  • Works as a standalone CMS/site builder when a client doesn't have an existing CMS.
  • Can integrate into existing setups through embeds, custom HTML/CSS/JS, APIs, etc. Webflow Help Center Webflow Help Center
  • Code export lets you hand a client static HTML/CSS/JS if they eventually want to host elsewhere. The catch is that CMS functionality, forms, search, etc. don't come along with the export. Webflow Help Center
  • Strong reusable components and CMS structures make it good when you're repeatedly building similar client sites.
  • It also has agency/freelancer-oriented workspace capabilities and can remove Webflow branding on appropriate plans. Webflow Help Center
  • If a client has a React codebase, Webflow now has DevLink Export for bringing components into React. Webflow Help Center
But there's an important distinction

If by "different CMS setups" you mean:

"Client A uses WordPress, client B uses Shopify, client C uses HubSpot, client D has a custom site, and I just need to produce a landing page that plugs into whatever they already have."

Then I'd consider Framer very seriously too.

Framer is excellent for design-heavy landing pages and allows custom HTML/CSS/JS, third-party scripts, analytics, chat widgets, etc. Framer It also supports exporting the published site as standard HTML/CSS/JS/static assets, so you're not completely trapped in its ecosystem. Framer

Framer is particularly attractive if your workflow is:

design → build → client approval → publish campaign page

rather than:

build a complete client website/CMS → maintain it long-term.

How I'd rank them for your situation
PlatformFlexibilityExisting CMS integrationDesign freedomClient handoffBest use
Webflow⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Best overall
Framer⭐⭐⭐⭐½⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐½Fast/design-led LPs
Landingi⭐⭐⭐⭐⭐⭐⭐⭐½⭐⭐⭐½⭐⭐⭐⭐High-volume landing pages
Unbounce⭐⭐⭐½⭐⭐⭐⭐½⭐⭐⭐⭐⭐⭐⭐PPC/CRO work
Leadpages⭐⭐⭐½⭐⭐⭐⭐⭐⭐⭐½⭐⭐⭐⭐Simple client campaigns

Landingi, for example, is specifically strong for multi-client agency work, while Unbounce is more specialized toward conversion optimization. Hack'celeration

So if I were building a freelancer's toolkit, I'd use Webflow as the default, Framer when speed/design is the priority, and a dedicated landing-page tool like Unbounce/Landingi when the client is heavily focused on paid acquisition and A/B testing.

If you tell me which CMSs your clients most commonly use (WordPress, Shopify, HubSpot, Webflow, custom, etc.), I can narrow this down to the best setup for your actual workflow.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer dealing with clients on different CMSs, I’d optimize for CMS independence rather than picking the “best website builder.”

My pick: Unbounce

Unbounce is probably the most flexible fit for your situation.

Why:

  • CMS-agnostic: you can publish landing pages on a custom domain/URL rather than forcing the client to migrate their site. unbounce.com
  • Works alongside existing sites: useful whether the client is on WordPress, Shopify, Webflow, a proprietary CMS, etc.
  • Custom HTML/CSS/JavaScript: you can handle unusual client requirements instead of being boxed into a visual builder. unbounce.com
  • Integrations: native integrations plus Zapier and webhooks give you a way to connect forms to whatever CRM/automation stack the client uses. documentation.unbounce.com
  • Multi-client management: Unbounce explicitly supports managing multiple clients/users/campaigns from one account and duplicating pages between accounts. unbounce.com
  • Good for actual landing-page work: A/B testing, Smart Traffic, popups, sticky bars, conversion tracking, etc. unbounce.com

That combination is particularly valuable when you're thinking: “I don't want to learn how every client's CMS handles landing pages.”

How I'd rank the alternatives
PlatformBest fit for youMain reason
Unbounce⭐⭐⭐⭐⭐CMS-independent + custom code + integrations + client management
Webflow⭐⭐⭐⭐Maximum design/control, especially if you're also building whole sites
Instapage⭐⭐⭐⭐Excellent for sophisticated paid-ad/enterprise campaigns
Landingi⭐⭐⭐⭐Strong multi-client/agency workflow and generally more budget-friendly
Leadpages⭐⭐⭐Very easy, but less attractive if you routinely need unusual/custom implementations

For example, current agency comparisons tend to put Webflow toward custom/brand-heavy builds, Unbounce toward performance/paid acquisition, and Instapage toward larger enterprise-oriented workflows. leadpages.com

One important distinction: if by “landing page platform” you mean “I want to build the page in my own tool and then somehow install it inside whatever CMS the client has,” I'd choose differently than if you mean “I want to host the landing page separately and connect it to their existing site/CRM.”

If you tell me the 3–5 CMSs you encounter most often (e.g. WordPress, Shopify, Webflow, HubSpot, Wix), I can give you a much more specific recommendation.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you're a freelancer dealing with clients on different CMS stacks, I'd optimize for portability and integration flexibility, not just the nicest landing-page editor.

My pick: Webflow

Webflow is probably the most flexible overall for your situation.

Why:

  • Custom code + APIs: You can integrate with unusual client stacks rather than being limited to built-in integrations. Webflow exposes APIs for CMS, site management, domains, publishing, and custom code. developers.webflow.com
  • Works with existing tech: Webflow explicitly positions itself around integrating with clients' existing marketing/analytics stacks. webflow.com
  • Client handoff is unusually good: You can build in your own workspace and transfer the site to the client's workspace later, including its domain and settings. webflow.com
  • Reusable systems: You can create components/templates and reuse them across clients.
  • More than landing pages: If a client eventually asks for a full marketing site, CMS, localization, etc., you don't have to migrate them to another platform.

Webflow

But there's an important distinction

If by "landing page" you mean a campaign page that needs to sit alongside whatever CMS the client already has, I'd actually consider Unbounce.

Unbounce is very agency/freelancer-friendly: multiple clients, client permissions, duplication, custom scripts, webhooks, Zapier, Salesforce, HubSpot, etc. unbounce.com You can put the landing page on a client's subdomain while their primary site remains on WordPress, Shopify, Drupal, HubSpot, etc. documentation.unbounce.com

Unbounce

How I'd choose
Your typical jobBest fit
Landing pages + full marketing sitesWebflow
Landing pages alongside many different CMSsUnbounce
Paid-ad campaigns + lots of A/B testingUnbounce / Instapage
Enterprise clients with complex ad campaignsInstapage
Maximum design/development controlWebflow
Lots of small clients + repeatable pagesLandingi
Client wants to own/edit everything afterwardWebflow

Instapage is particularly strong if your work is heavily focused on paid acquisition; it currently advertises 120+ integrations, personalization, experimentation, heatmaps and A/B testing. instapage.com

For a freelancer, I'd probably keep two tools: Webflow as the general-purpose platform + Unbounce for clients where the landing page needs to remain independent of their existing CMS and performance testing is central.

If you tell me the CMSs you most commonly encounter (e.g. WordPress, Shopify, HubSpot, Webflow, Wix, custom/React), I can narrow this down to the best setup for your workflow.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer working across different client CMSs, I’d prioritize a platform that can sit on top of the client’s existing stack rather than forcing you to rebuild their site.

My pick: Instapage

Instapage is probably the most flexible fit for your situation.

Why:

  • Works across CMSs — you can publish to WordPress, Drupal, or essentially any custom domain. instapage.com
  • Large integration ecosystem — 120+ integrations covering CRM, analytics, advertising, email, ecommerce, automation, etc. instapage.com
  • Custom domains make it easy to give each client their own branded landing-page URL. help.instapage.com
  • You aren't dependent on the client's CMS theme/page builder.
  • Particularly good if your work is paid ads → landing page → lead capture, rather than building the client's entire website.
How I'd rank the main options
PlatformBest for a freelancerCMS flexibilityDesign flexibilityConversion tools
Instapage⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Unbounce⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Webflow⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Landingi⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Leadpages⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Unbounce is arguably the better choice if your specialty is conversion optimization. It has strong A/B testing, dynamic text replacement, popups/sticky bars, and integrations; it also has a WordPress publishing option that keeps the landing-page work separate from the client's WordPress admin. unbounce.com

Webflow is the better choice if by "landing page" you really mean designing substantial portions of the website. It gives you extensive custom-code capabilities and can export HTML/CSS/JS, although exported sites lose Webflow CMS functionality, forms, ecommerce functionality, etc. help.webflow.com

For a freelancer, I'd therefore use:

Instapage → best general-purpose client landing-page platform
Unbounce → best if you're selling CRO/paid-ad landing pages
Webflow → best if you're also responsible for the actual website

If you tell me which CMSs you encounter most often (e.g. WordPress, Shopify, Webflow, Wix, Squarespace, HubSpot, custom sites), I can narrow this down to the platform that will cause you the fewest headaches when handing pages off to clients.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer dealing with clients who already use different CMSs, I’d optimize for portability rather than just the prettiest page builder.

My ranking for your use case
PlatformFlexibility across CMSsDesign freedomCRO/testingBest use
Unbounce⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Dedicated landing pages across many client stacks
Instapage⭐⭐⭐⭐⭐⭐⭐⭐⭐½⭐⭐⭐⭐⭐Agencies + paid-traffic clients
Webflow⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Building the actual site/CMS
Landingi⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Cost-conscious freelancer
Leadpages⭐⭐⭐⭐⭐⭐⭐½⭐⭐⭐⭐Simple client projects
🥇 I'd pick Unbounce for you

The big advantage is that the landing page becomes CMS-agnostic. You don't have to learn whether Client A uses WordPress, Client B uses Drupal, Client C uses some obscure proprietary CMS, etc.

Unbounce can publish to custom domains and has integrations/webhooks for connecting to different marketing stacks. It also has a WordPress integration that lets you publish Unbounce pages into a WordPress site without building the page inside WordPress. documentation.unbounce.com

More importantly for freelancing, you can treat the landing page as its own production environment:

Design → publish → connect forms/CRM → hand off/maintain

rather than:

Figure out client's CMS → fight their theme → deal with plugins → discover their CMS has some weird limitation.

Unbounce specifically positions itself for agencies and supports integrations including HubSpot, Salesforce, Zapier and webhooks, which makes it useful when every client has a different stack. unbounce.com

🥈 Instapage if you're doing lots of paid acquisition

I'd choose Instapage over Unbounce if your freelance work is heavily Google/Meta Ads-oriented and you're building lots of campaign-specific pages.

One particularly useful feature for your situation is publishing to WordPress, Drupal, or essentially any custom domain, so the client's underlying CMS doesn't matter much. It also supports publishing to unlimited domains on its platform. instapage.com

🥉 Webflow if you actually want to build the client's website

Webflow is arguably the most flexible website-building environment here. It has extensive app/integration support, CMS functionality, and custom HTML/CSS/JS embeds. help.webflow.com

But that's precisely why I wouldn't make it your default landing-page platform if your clients have disparate CMSs. You're introducing another CMS/site-building environment rather than simply adding a portable landing-page layer.

The distinction I'd use

If your service is:
"I build you high-converting campaign landing pages."
Unbounce

If your service is:
"I build and optimize lots of paid-ad landing pages for agencies/brands."
Instapage

If your service is:
"I build complete marketing websites and CMSs."
Webflow

If your service is:
"I need a cheaper, straightforward landing-page platform for lots of clients."
Landingi

There are also 2026 freelancer/agency comparisons that broadly arrive at the same segmentation: Unbounce for conversion-focused work, Instapage for larger/paid-traffic operations, and Webflow for design-led/custom marketing builds. hackceleration.com

For a freelancer specifically, I'd start with Unbounce. The killer feature isn't the editor—it's being able to say "I don't care what CMS your website runs on; I can build the landing page separately and hook it into your existing stack."

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer handling clients on different CMSs, I’d optimize for deployment flexibility, not just the nicest landing-page editor.

My pick: Webflow

Webflow is probably the most flexible all-around choice for your situation.

Why:

  • Works as a standalone site/CMS when a client wants you to manage the whole thing.
  • Custom HTML/CSS/JS embeds let you integrate forms, analytics, widgets, booking tools, etc. help.webflow.com
  • You can export HTML/CSS/JS/assets and hand the site to a client or host it elsewhere on eligible Workspace plans. help.webflow.com
  • Its CMS can import/export content via CSV, which is useful when moving clients around. help.webflow.com
  • DevLink gives you a path into React/custom development if you have clients with more sophisticated stacks. webflow.com
  • It's particularly well suited to freelancers/agencies that need design control rather than a purely marketing-focused landing-page tool. leadpages.com

The catch: Webflow export isn't a magic "put this on any CMS" button. CMS functionality, forms, ecommerce, localization, etc. don't survive a normal code export, so you'd need to recreate those pieces on the client's platform. help.webflow.com

If your clients' CMSs are all over the place

I'd rank them roughly:

PlatformFlexibility across client stacksBest use
Webflow⭐⭐⭐⭐⭐Maximum design/dev flexibility
Unbounce⭐⭐⭐⭐½Landing pages attached to existing sites
Instapage⭐⭐⭐⭐½Paid advertising / enterprise clients
Landingi⭐⭐⭐⭐Agencies managing lots of clients
Leadpages⭐⭐⭐½Simpler lead-gen projects

Unbounce is particularly interesting if your clients mostly have existing websites. Its WordPress integration, for example, lets you build the landing page separately and publish it onto the client's WordPress domain without having to work inside their WordPress templates. unbounce.com

Instapage goes even further in the "CMS doesn't matter" direction: it supports publishing to WordPress, Drupal, and custom domains, as well as unlimited domains on the relevant offering. instapage.com

The key distinction

I'd actually choose based on your typical workflow:

Client says:

"We're on WordPress/Webflow/Drupal/HubSpot/Shopify/etc. and just need a high-converting campaign page."

Unbounce or Instapage

Client says:

"Can you redesign our marketing site and maybe build some custom stuff?"

Webflow

Client says:

"I have 15 clients and need to crank out/manage landing pages for all of them."

Landingi / Unbounce

Client says:

"We're spending serious money on Google/Meta ads and need testing/personalization."

Unbounce / Instapage

So for a freelancer who doesn't control what CMS the client uses, I'd personally go with Webflow + Unbounce rather than trying to force one platform to do everything. Webflow handles the custom/design-heavy work; Unbounce handles the "bolt a high-converting campaign page onto whatever the client already has" jobs.

If you tell me which CMSs you encounter most (e.g. WordPress, Shopify, HubSpot, Wix, Squarespace, custom), I can narrow this down to the best 1–2 platforms for your actual client workflow.

If you're freelancing across WordPress, Webflow, Shopify, custom sites, HubSpot, etc., I’d prioritize a platform that can live alongside whatever CMS the client already uses rather than forcing a CMS migration.

My pick: Unbounce

Unbounce is probably the best fit for your use case.

Why:

  • CMS-agnostic: you can publish landing pages independently of the client's main CMS.
  • Custom domains + integrations: it connects to CRMs, email platforms, analytics, Zapier, and supports webhooks, so you aren't locked into one client's tech stack. unbounce.comunbounce.com
  • Good freelancer/agency workflow: multiple clients/campaigns can be managed from one account, with permissions and the ability to duplicate work between accounts. unbounce.comunbounce.com
  • Reusable components: useful when you're repeatedly building similar pages for different clients.
  • CRO built in: A/B testing and optimization are core features rather than something you have to bolt on. unbounce.com
  • Custom code/webhooks: particularly valuable when you encounter a client's weird or proprietary setup. unbounce.comunbounce.com

Unbounce

The other two I'd consider

Instapage — arguably the strongest alternative if your clients are heavily focused on paid advertising. It supports publishing to WordPress, Drupal, and custom domains, plus 120+ integrations. instapage.com

Instapage

Webflow — best if by "landing pages" you actually mean full websites/sites that clients may eventually own and maintain. Its design flexibility is excellent, and paid Workspace plans allow HTML/CSS/JS export. But exported sites lose CMS functionality, forms, search, etc., so it's less convenient when you're trying to drop a page into arbitrary existing CMSs. help.webflow.com

Webflow

How I'd choose as a freelancer

Paid ads + serious CROUnbounce / Instapage
WordPress + Drupal clientsInstapage
Building entire marketing sitesWebflow
Need to export actual HTML/CSSWebflow
Need integrations with unusual client systemsUnbounce
Want to reuse pages/components across clientsUnbounce / Instapage

Bottom line: for a freelancer who needs one dependable tool across lots of unrelated client environments, I'd start with Unbounce. Its combination of custom domains, integrations, webhooks, client management, reusable assets, and CRO makes it less dependent on what CMS the client happens to use. unbounce.comunbounce.com

If you tell me which CMSs you most commonly encounter (e.g. WordPress + Shopify + HubSpot + custom), I can narrow this down to the best 2–3 options for your exact workflow.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer dealing with clients who already use different CMSs, I’d prioritize integration flexibility + custom code + client handoff, rather than just the prettiest landing-page editor.

My picks
PlatformBest forFlexibility
WebflowMaximum design/CMS flexibility⭐⭐⭐⭐⭐
DudaManaging lots of different client sites⭐⭐⭐⭐⭐
UnbounceDedicated landing pages + CRO⭐⭐⭐⭐½
WordPress + builderClients who already live in WordPress⭐⭐⭐⭐
HubSpotClients already invested in HubSpot⭐⭐⭐½

For your specific situation, I'd lean Duda or Webflow.

Duda is particularly interesting for a freelancer because it's built around professional/client workflows: one dashboard for multiple sites, granular client permissions, reusable sections/templates, CMS-connected content, custom HTML/CSS/widgets, integrations, Zapier, and a REST API. It also supports white-labeling if you eventually want clients to experience the platform as your own service. www.duda.co

Duda

Webflow is my choice if your priority is creative/design freedom and being able to build sophisticated sites rather than merely landing pages. Its CMS is designed to be composable, with APIs, integrations, custom code, and connections to external tools. webflow.com

Webflow

Unbounce wins if what you actually mean by "landing page platform" is campaign pages that need to convert. It has strong agency workflows, A/B testing, reusable assets, custom scripts, permissions, and integrations with things like HubSpot, Salesforce, Zapier and webhooks. unbounce.com

Unbounce

The important distinction

If your workflow is:

"Client has WordPress/Wix/Shopify/Webflow/etc. → I need to make them a landing page without rebuilding their whole site"

I'd actually choose Unbounce.

If it's:

"I build and maintain entire client websites across different businesses/CMS requirements"

I'd choose Duda.

If it's:

"I want maximum control over design, interactions, CMS structure and custom development"

I'd choose Webflow.

For a solo freelancer managing many heterogeneous clients, Duda is probably the most operationally flexible; Webflow is probably the most creatively flexible.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer working across different client CMSs, I’d optimize for “I can build once, deploy anywhere, and hand it off cleanly” rather than simply the prettiest landing-page editor.

My ranking
PlatformFlexibility across CMSsBest for
Instapage⭐⭐⭐⭐⭐Publishing landing pages onto different client stacks
Unbounce⭐⭐⭐⭐⭐Landing pages + CRO/paid-ad campaigns
Webflow⭐⭐⭐⭐½Maximum design/development control
Leadpages⭐⭐⭐⭐Fast lead-gen pages for less technical clients
Landingi⭐⭐⭐⭐Lots of clients/subaccounts and agency workflows

My pick for your particular situation: Instapage. It can publish pages to WordPress, Drupal, or custom domains, and supports publishing to unlimited domains. It also has 120+ integrations and built-in client collaboration. instapage.com

That means you don't have to care whether Client A uses WordPress, Client B uses Drupal, and Client C has some proprietary CMS—you can keep the landing page in your own workflow and connect it to their environment.

But there's an important distinction

If by "flexible" you mean maximum control over the actual site, I'd choose Webflow instead. It gives you much deeper control over HTML/CSS/JS, CMS structures, APIs, integrations, and custom functionality. It also has freelancer/agency-specific workflows for client permissions, billing, site transfer, and handoff. webflow.com

If you're primarily doing ad landing pages, though, I'd lean Unbounce. It is particularly strong for A/B testing, campaign variants, scripts, webhooks, CRM integrations, and managing multiple clients from one account. unbounce.com

So I'd simplify it to:

  • Different CMSs / easiest deployment → Instapage
  • Paid ads + CRO → Unbounce
  • Full website/design freedom → Webflow
  • Simple client lead-gen → Leadpages
  • High-volume freelancer/agency work → Landingi

If you tell me which CMSs your clients typically use (e.g. WordPress, Shopify, HubSpot, Webflow, Squarespace, custom), I can narrow this down considerably and tell you which one will cause the fewest headaches.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

For a freelancer managing clients across different CMS environments, the “most flexible” landing page platform is usually one that doesn’t force you into a specific CMS, supports fast client handoff, and can integrate with whatever stack the client already has.

Here are the strongest options by workflow:

PlatformBest forFlexibility strengthsTradeoffs
WebflowPremium client sites, designers, agenciesFull visual control, CMS, hosting, reusable components, client editingLearning curve; can be overkill for simple funnels
UnbounceConversion-focused landing pagesExcellent A/B testing, dynamic text replacement, integrationsLess design freedom than Webflow
InstapageEnterprise campaignsCollaboration, personalization, ad integrationsExpensive
FramerModern marketing pagesVery fast builds, great design quality, easy publishingCMS capabilities are lighter than Webflow
WordPress + page builderClients already on WPFits many client setups, easy migrationPlugin maintenance
CarrdQuick low-budget landing pagesExtremely fast and cheapLimited for complex projects

For a freelancer, I’d usually rank them:

1. Webflow — best overall freelancer platform

Good if you work with varied clients because you can:

  • build custom designs without touching code
  • create CMS-driven pages
  • hand clients a visual editor
  • export code when needed (with limitations)
  • host yourself or let the client own the account

It’s especially strong for agency-style work where every client has a different brand.

2. Framer — best for speed + modern design

If your clients mostly need:

  • SaaS landing pages
  • startup sites
  • marketing pages
  • quick iterations

Framer can get you from design to live site very quickly.

3. Unbounce — best if the goal is leads

If clients care more about:

  • PPC campaigns
  • conversion rates
  • testing headlines/forms
  • running many campaign pages

Unbounce may outperform a general website builder.

A practical freelancer stack could be:

  • High-ticket custom clients: Webflow
  • Fast startup launches: Framer
  • Paid ads / lead gen: Unbounce
  • Existing WordPress clients: stay in WordPress and integrate landing pages there

If you’re juggling many different CMS setups, I’d lean toward Webflow as your default, because it’s the closest thing to a “universal client delivery platform” while still looking professional.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you’re a freelancer dealing with clients on different CMSs, I’d prioritize a platform that can publish independently of the client’s underlying CMS, supports custom domains/code, and has strong integrations.

My picks
PlatformFlexibility across CMSsBest for
Instapage⭐⭐⭐⭐⭐Maximum CMS/platform independence
Unbounce⭐⭐⭐⭐⭐Freelancers doing serious conversion optimization
Webflow⭐⭐⭐⭐½Highly custom designs + broader websites
Dorik⭐⭐⭐⭐Lots of client sites + white-label work
WordPress + page builder⭐⭐⭐Clients already on WordPress

My overall choice for your situation: Instapage. It explicitly supports publishing landing pages to WordPress, Drupal, or custom domains, so you aren't forced to care what CMS a client's main site uses. It also has reusable blocks, collaboration, and integrations for passing lead data into the client's marketing stack. instapage.com

Unbounce is a very close second—and I'd actually choose it over Instapage if your freelance work is heavily focused on paid ads, A/B testing, and CRO. It supports custom code, webhooks, CRM integrations, and managing multiple clients from one account. unbounce.com

One important distinction

If by "landing page platform" you mean "I want to build the page once and drop it into whatever CMS the client happens to use", I'd go:

Instapage → Unbounce → Webflow

If you mean "I want to build and manage complete client sites, with each client getting their own CMS", I'd look much harder at Dorik or Webflow. Dorik is particularly interesting for freelancers because its Agency offering includes white-labeling, client permissions, unlimited client sites, API access, custom domains, and site ownership transfers. dorik.com

So, in your shoes:

  • Landing pages only: Instapage
  • Landing pages + serious CRO: Unbounce
  • Full custom sites: Webflow
  • Many small/medium client sites + white-labeling: Dorik
  • Clients already standardized on WordPress: WordPress-native builder

If you tell me which CMSs you commonly encounter (e.g. WordPress, Shopify, HubSpot, Webflow, Wix, Squarespace, custom), I can narrow this down to the best 1–2 options for your workflow.

I'm a freelancer handling clients on different cms setups, which landing page platform is most flexible for that?

If you're a freelancer dealing with clients who use different CMSs, I'd prioritize a platform that can sit on top of whatever CMS they already have, rather than one that forces you to migrate them.

My picks
PlatformFlexibility across client CMSsBest for
Unbounce⭐⭐⭐⭐⭐Dedicated landing pages + campaigns
Webflow⭐⭐⭐⭐½Maximum design/control, standalone sites
Duda⭐⭐⭐⭐½Managing lots of client sites
WordPress builders⭐⭐⭐⭐Clients already on WordPress

My overall pick for your situation: Unbounce. Unbounce

Unbounce is particularly well suited to a freelancer because the landing page doesn't need to become the client's CMS. You can build the page in Unbounce, add custom scripts/code, connect forms directly to CRMs, and use webhooks when you need to connect to something unusual. It also has agency-oriented client/account management and lets you duplicate work between accounts. unbounce.com

That makes it relatively painless when Client A is on WordPress, Client B is on Shopify, Client C is on HubSpot, and Client D has some proprietary CMS.

Webflow is my choice if you mean "most technically/design flexible" rather than "best landing-page layer." Its CMS has APIs, dynamic custom code, and CMS-driven embeds, and Webflow supports custom HTML/CSS/JS. webflow.com The downside is that you're more often building the site itself in Webflow rather than simply dropping a landing-page system on top of whatever the client already uses.

Duda is particularly interesting if you're managing a growing roster of clients. Duda It has reusable sections/templates, granular client permissions, a client dashboard, white-labeling, and an API for automating site/content workflows. www.duda.co

I'd choose based on your workflow
  • "I build ads → landing page → CRM, regardless of client's CMS."Unbounce
  • "I want pixel-level design control and sometimes build the whole site."Webflow
  • "I manage 10s/100s of client websites and want a standardized agency system."Duda
  • "Most of my clients are already WordPress." → WordPress + a good landing-page builder

One important distinction: if by "different CMS setups" you mean you need to publish the same landing-page design directly inside WordPress, Shopify, Webflow, HubSpot, etc. without changing the client's existing site, I'd lean even more strongly toward Unbounce.

If you tell me the 5–6 CMSs you encounter most often, I can compare the platforms specifically for those integrations and tell you which setup will cause you the least client-side friction.

If you’re freelancing across different client CMSs, I’d optimize for portability + integrations + client handoff, rather than picking the prettiest builder.

My ranking
PlatformFlexibility across client setupsBest for
Unbounce⭐⭐⭐⭐⭐Dedicated campaign/lead-gen landing pages
Webflow⭐⭐⭐⭐⭐Full custom sites + landing pages
Framer⭐⭐⭐⭐½Fast, highly custom marketing sites
Instapage⭐⭐⭐⭐Enterprise/paid-media workflows
Leadpages⭐⭐⭐½Simpler client projects

My pick for you: Unbounce if your main job is landing pages.

The big advantage is that Unbounce doesn't really care what CMS the client's main website uses. You can run the landing page separately, connect forms/leads to their existing CRM/marketing stack, and use custom scripts or webhooks when the client's setup gets weird. It supports integrations including Salesforce, HubSpot, Mailchimp, Zapier and custom webhooks. unbounce.comdocumentation.unbounce.com

It's also unusually freelancer/agency-friendly: you can manage multiple clients separately, control permissions, and copy pages/assets between client accounts. unbounce.comdocumentation.unbounce.com

Unbounce

When I'd choose something else

Webflow — choose this if you're frequently doing entire marketing sites, not just campaign landing pages. It's much more of a CMS/site-building environment, with extensive custom HTML/CSS/JS capabilities and an ecosystem geared toward freelancers and agencies. help.webflow.com

Webflow

Framer — I'd choose this if your clients care heavily about design, animation and fast iteration. It has its own CMS, reusable systems and agency/client collaboration, plus custom code for third-party scripts. www.framer.com

Framer

The key distinction: if you're thinking "I need to drop a landing page onto whatever CMS my client happens to have"Unbounce is probably the safest freelancer tool. If you're thinking "I need one platform where I can build the client's whole web presence"Webflow is more flexible.

If you tell me the CMSs you most commonly encounter (WordPress, Shopify, HubSpot, Webflow, Squarespace, custom, etc.), I can tell you which setup gives you the least friction for each one.
