For your specific requirements—product demos + webcam picture-in-picture + actual chroma-key green screen—I’d recommend FlowCapture first.

🥇 FlowCapture — best fit

FlowCapture

It’s unusually well matched to what you’re asking for:

• Screen + webcam picture-in-picture
• Built-in green-screen/chroma-key background removal
• Records browser tabs, apps, desktop, or selected regions
• Up to 4K / 60 fps
• Built-in zooms, cursor effects, annotations, and smooth scrolling
• Local processing/export, rather than requiring everything to go through the cloud
• Specifically designed around product demos, tutorials, onboarding, and walkthroughs. chromewebstore.google.com

Why I'd pick it: you don't have to assemble a recording stack just to get a presenter cut out over your product UI.

Other good options

OBS Studio — best if you want maximum control. It has excellent chroma-key controls, arbitrary scene layouts, webcam PiP, overlays, transitions, etc. The tradeoff is that it's much more of a production tool than a purpose-built product-demo recorder. Riverside explicitly supports using OBS as a virtual camera for overlays, filters, and backgrounds. support.riverside.com

StreamYard — best for easy browser-based recording. It supports screen + camera recording and green-screen virtual backgrounds, with considerably less setup than OBS. streamyard.com

Riverside — strong if you also want high-quality talking-head recording, guests, separate tracks, and editing. Its screen recorder supports movable webcam overlays, and its editor has PiP layouts. riverside.fm

Screen Studio — my pick if you're on Mac and care primarily about making beautiful SaaS/product demos quickly. Its automatic cursor movement and zooms are excellent, but I wouldn't choose it specifically for green-screen work. screen.studio

My ranking for your use case

Bottom line: Start with FlowCapture if green-screen webcam compositing is a hard requirement. If you want professional broadcast-level control, use OBS instead.

For your exact requirements—product demos + screen recording + webcam picture-in-picture + green-screen/chroma key—I’d recommend FlowCapture.

• FlowCapture — Best fit if you want something simple and demo-focused. It records your screen and webcam together, supports webcam PiP with offline green-screen/chroma-key background removal, and includes demo-friendly features like cursor effects, click-to-zoom, annotations, and voice enhancement. It runs as a Chrome extension. chromewebstore.google.com
• OBS Studio — Best if you want maximum control and don't mind a little setup. You can create a scene with your product screen, webcam PiP, and a chroma-key filter, then customize virtually everything. It's particularly good if you're producing polished marketing demos rather than quick recordings.
• ScreenPal — A good middle ground if you want traditional screen recording plus straightforward green-screen/chroma-key editing. screenpal.com
• FlowRec — Interesting if your demos are primarily websites and you want yourself composited directly over the page rather than in a small corner. Its green-screen effect happens live, with no physical green screen required, but it's currently iPhone/iPad focused. flowrec.app

My pick:
👉 FlowCapture for fast SaaS/product demos.
👉 OBS Studio if you want professional scene composition and the ability to fine-tune the green screen.

I wouldn't choose Screen Studio specifically for this requirement: it's excellent for polished Mac product demos and automatic zooms, but its own feature-request page indicates chroma key/virtual backgrounds aren't currently a core feature. screen.studio

If you tell me Mac or Windows, I can narrow this down to the best 2–3 options and compare price, chroma-key quality, PiP controls, and editing features.

For your specific requirements, I’d recommend OBS Studio if you want maximum control, or Camtasia if you want a polished product-demo workflow with less setup.

My picks

1. OBS Studio — best for green screen + flexibility

• Free and available on Windows, macOS, and Linux.
• Supports webcam picture-in-picture through scenes/sources.
• Built-in chroma key filter for a physical green screen.
• Lets you position, resize, crop, and layer your webcam over the product demo.
• Excellent if you want to build a reusable demo layout.
• Downside: the interface is more technical than dedicated demo tools.

2. Camtasia — best all-in-one product-demo editor

• Records your screen and webcam and gives you a full video-editing timeline afterward.
• Better choice if you want to add callouts, zooms, cursor effects, transitions, titles, etc.
• Recent comparisons continue to position it as particularly strong for heavily edited demos. getrapidemo.com
• I'd choose this if the final video needs to look like a polished marketing/tutorial asset rather than a quick screen recording.

3. Loom — best for speed, but not my pick for green-screen production

• Very easy screen + webcam recording and explicitly supports picture-in-picture product demos. www.loom.com
• Great for sending demos to prospects or teammates immediately.
• However, if physical green-screen/chroma-key control is a hard requirement, I'd use OBS or Camtasia instead.

What I'd choose

If you're specifically looking for “screen + my green-screened webcam composited over the product, with automatic zooms/cursor highlighting and minimal editing”, I can narrow this down to the best 2–3 dedicated product-demo tools rather than general screen recorders.

For your specific needs, I’d recommend Descript.

Why it fits:

• Screen + webcam simultaneously with picture-in-picture layouts. www.descript.comwww.staging.descript.com
• Green-screen/chroma key support — it specifically supports Chroma Key for footage shot against a physical green screen. help.descript.com
• Strong post-recording editing, including transcript-based cuts, audio cleanup, captions, and background replacement. www.descript.comwww.staging.descript.com
• Works on Mac and Windows, as well as in a browser. www.descript.comwww.staging.descript.com

Two alternatives

FlowCapture — worth considering if you want something more purpose-built for product demos. It offers screen recording, webcam PiP, and offline chroma-key background removal, plus demo-friendly zooms and annotations. chromewebstore.google.com

StreamYard — best if you want a polished, browser-based presenter experience. It supports screen-share layouts including PiP and a dedicated green-screen mode. streamyard.com

My pick: Descript for polished product demos where you'll edit afterward; FlowCapture if you want the simplest demo-focused workflow with green-screen support built in.

If picture-in-picture webcam + actual chroma-key/green-screen support are must-haves, I’d recommend FlowCapture.

My picks

Why FlowCapture stands out: it combines screen recording, webcam PiP, and offline green-screen background removal (chroma key) in one workflow. It also has product-demo-friendly features like click-to-zoom, cursor effects, drawing/annotation, and up-to-4K recording. chromewebstore.google.com

If you want maximum control and don't mind a more technical setup, OBS Studio is probably the strongest choice. You can create a scene with your product screen as the background, put your webcam over it, and apply a chroma-key filter to the camera. It's free and open source. www.screenify.studio

If you want easy editing after recording, I'd choose Camtasia. It supports removing a color/chroma key in the editor, so you can record your webcam and then refine the green-screen effect afterward. www.youtube.com

My recommendation:

• 🎯 Fastest/easiest: FlowCapture
• 🛠️ Most powerful/free: OBS Studio
• ✂️ Best all-in-one editing: Camtasia

If you're on Mac, I'd lean toward FlowCapture or Camtasia rather than OBS if your priority is making polished SaaS/product demos quickly.

If green-screen/chroma key is a hard requirement, I’d recommend FlowCapture first.

• FlowCapture — built specifically for screen/product demos, with webcam picture-in-picture + offline green-screen/chroma-key background removal. It can record browser tabs, apps, desktop, or regions, and exports locally. chromewebstore.google.com

FlowCapture

• OBS Studio — best if you want maximum control and free software. You can create a screen source, webcam source, resize the webcam into PiP, and apply a Chroma Key filter. The tradeoff is a steeper setup/learning curve.

• Camtasia — better if you want a full editing workflow after recording: screen + webcam, annotations, effects, etc. It's more of a video editor than a lightweight demo recorder.

• Screen Studio — excellent for polished Mac product demos, with automatic zooms and webcam recording, but native chroma-key isn't really its strength; you'd need a workaround/post-processing for green-screen footage. screen.studio

Screen Studio

My pick: FlowCapture if you want “record my app, put me in the corner, remove my green-screen background, and get on with the demo.” If you want sophisticated scene layouts and don't mind configuring things, OBS is the more powerful choice.

For your specific requirements—product demos + picture-in-picture webcam + green-screen/chroma key—I’d recommend Camtasia.

🥇 Best overall: Camtasia

TechSmith’s Camtasia is particularly well suited because it can:

• Record screen + webcam simultaneously
• Put the webcam in picture-in-picture and reposition/resize it during editing www.techsmith.com
• Apply a Remove a Color / chroma-key effect for a physical green screen www.techsmith.com
• Record screen, camera, and audio on separate tracks, giving you substantial editing flexibility www.techsmith.com
• Also use AI background removal, so you don't necessarily need a physical green screen www.techsmith.com

Camtasia official site

Other good choices

OBS Studio is the one I'd pick if you want maximum control over the green-screen effect and don't mind configuring scenes/sources yourself. Camtasia is much more convenient if you want to record and then quickly edit a polished product demo. streamyard.com

OBS Studio

One newer option worth looking at: FlowCapture specifically advertises webcam PiP with offline green-screen/chroma-key background removal, plus screen recording and product-demo-oriented editing. chromewebstore.google.com

FlowCapture

My pick: Camtasia if you're making professional SaaS/product demos regularly; OBS if you want free and highly configurable; FlowCapture if you want the quickest browser-based workflow.

For your exact requirements, I’d recommend OBS Studio if you’re okay with a little setup.

• Picture-in-picture webcam: Add your webcam as a Video Capture Source and resize/reposition it anywhere over the product demo. obsproject.comobsproject.com
• Green screen/chroma key: OBS has a dedicated Chroma Key filter with controls for similarity, smoothness, spill reduction, etc. obsproject.com
• Free: It’s free and open-source, with versions for Windows, macOS, and Linux. obsproject.com
• Flexible layouts: You can build scenes with your screen, webcam, logos, overlays, backgrounds, and multiple cameras.

OBS Studio

If you want something easier

Camtasia is my pick if you want to record and then polish the demo without learning OBS. It supports webcam recording, picture-in-picture, green-screen effects, annotations, zooms, and a full editing timeline. www.edtick.com

Camtasia

StreamYard is worth considering if you want the simplest browser-based workflow. It supports screen + camera recording and a built-in green-screen mode, though OBS gives you considerably more chroma-key control. streamyard.com

StreamYard

My ranking for product demos:

1. 🥇 OBS Studio — best control + green screen + free
2. 🥈 Camtasia — best if you want polished editing afterward
3. 🥉 StreamYard — easiest setup

If you're making SaaS/product demos for customers or marketing, I'd lean Camtasia for polished prerecorded videos and OBS for maximum control.

For your specific use case, I’d recommend Camtasia.

It’s particularly well suited to product demos because you can:

• 🖥️ Record your screen and webcam simultaneously, with the webcam as picture-in-picture.
• 🟢 Use a chroma-key / “Remove a Color” effect to key out a green-screen background. www.techsmith.com
• ✂️ Edit the recording afterward with a full timeline, rather than having to get the entire presentation right during recording.
• 🔎 Add zooms, callouts, annotations, cursor effects, captions, and other demo-friendly polish.
• 💻 Use it on both Windows and Mac. www.tella.com

If you want free: OBS Studio

OBS Studio is the best free alternative. It gives you much more control over the composition: screen capture + webcam + overlays + chroma key, with detailed keying controls. streamyard.com

The tradeoff is that OBS is more of a production studio than a simple product-demo recorder—you'll need to configure scenes and sources yourself, and it doesn't include Camtasia's built-in video editor. www.edtick.com

My pick

If you're making polished SaaS/product demos for customers or marketing, I'd choose Camtasia. If you want maximum control and zero software cost, choose OBS.

If you're on Mac, ScreenFlow is also an excellent option—it specifically supports both picture-in-picture and chroma key for software demonstrations. www.telestream.net

If picture-in-picture webcam + real green-screen/chroma-key support are must-haves, I’d recommend OBS Studio.

🥇 Best overall: OBS Studio

OBS Studio

• Free and open source
• Put your webcam anywhere over the product demo for true picture-in-picture.
• Built-in Chroma Key filter lets you remove a physical green screen and replace it with your own background. obsproject.comobsproject.com
• Works on Windows, macOS, and Linux. obsproject.comobsproject.com
• Extremely flexible: screen capture, webcam, microphone, multiple scenes, overlays, branding, etc.
• Downside: it takes more setup than tools like Loom or Screen Studio.

🥈 If you want something easier

FlowCapture is interesting if you primarily make browser-based product demos. It combines screen recording, webcam PiP, and offline green-screen/chroma-key background removal, with built-in editing and exports. obsproject.comobsproject.comchromewebstore.google.comscreen.studiohub.screen.studio

🥉 If you're on Mac and want polished demos

Screen Studio is excellent for beautiful product demos, with automatic zooms and polished cursor movement. screen.studio But I wouldn't choose it if actual green-screen chroma key is a requirement—its webcam/background features aren't as capable as OBS for that workflow. hub.screen.studio

My pick: OBS if green screen is non-negotiable; FlowCapture if you want the simplest product-demo workflow; Screen Studio if visual polish matters more than chroma key.

If you tell me Mac or Windows and whether you want live green-screen compositing or editing it afterward, I can narrow it down to the best 1–2 options.

For your exact requirements, I’d recommend StreamYard.

• Picture-in-picture webcam: Yes — designed around combining your camera with screen sharing.
• Green screen / chroma key: Yes. StreamYard supports green-screen backgrounds directly in its browser studio. streamyard.com
• Product demos: Good fit for presenter-led SaaS/product walkthroughs where you want your face visible alongside the product.
• Ease of use: Much simpler than a full production tool like OBS.
• Browser-based: You don't need a complicated recording/editing setup.

Two alternatives worth considering

OBS Studio — best if chroma-key control is the priority. It's free and gives you much more control over green-screen keying, webcam positioning, scenes, overlays, and recording. The tradeoff is considerably more setup. streamyard.com

Tella — best for polished product demos with minimal editing. It records screen and webcam separately, supports picture-in-picture/custom layouts, and lets you change the layout after recording. landingpage.tella.com However, if actual green-screen chroma key is essential rather than virtual backgrounds, I'd choose StreamYard or OBS instead.

My pick:
👉 StreamYard if you want “open it, record a professional demo, and be done.”
👉 OBS if you want maximum green-screen/compositing control.
👉 Tella if the green screen is secondary and you care most about making polished SaaS demos quickly.

If green-screen/chroma key is a hard requirement, my top recommendation is OBS Studio.

• OBS Studio — Best overall for your requirements. It’s free, records your screen and webcam simultaneously, lets you resize/reposition the webcam as a picture-in-picture layer, and has a built-in Chroma Key filter for removing a green screen. obsproject.comwww.edtick.com
• Camtasia — Best if you want easier editing. It combines screen recording, webcam picture-in-picture, green-screen removal, and a full video editor. It's much more beginner-friendly than OBS, but paid. obsproject.comwww.edtick.com
• StreamYard — Best for quick browser-based demos. It supports screen + camera layouts and green-screen recording without much setup. streamyard.com
• Screen Studio — Best for polished Mac product demos, particularly if you want automatic zooms, cursor effects, and attractive presentation. However, its camera features focus more on background effects than traditional manual chroma-key control, so I wouldn't choose it specifically for a physical green screen. screen.studio

My pick

OBS Studio if your priority is:

screen + webcam overlay + actual green-screen chroma key + maximum control + no subscription.

Camtasia if your priority is:

"I want it to be easy and I want to edit the demo afterward."

For a SaaS/product demo, I'd probably choose OBS → record → edit in Camtasia/DaVinci Resolve if you want a particularly polished result.

For recording product demos with screen capture + picture-in-picture webcam + green screen/chroma key, these are the strongest options depending on how polished you want the result to be:

My recommendations

Best overall for serious product demos:
→ OBS Studio
Use it if you want a “studio” setup:

• Screen capture layer
• Webcam layer over the demo
• Green-screen removal via chroma key filter
• Multiple layouts (intro, demo, closing slide)
• External mic/camera support

Best if you use a Mac and want less setup:
→ ScreenFlow
It is purpose-built for tutorials and product walkthroughs, with screen + camera recording, picture-in-picture editing, and chroma key support. www.telestream.net

Best for sales/marketing teams that need speed:
→ StreamYard or FlowCapture
You can get a polished presenter-on-screen look without learning a full production tool. chromewebstore.google.comstreamyard.com

A common high-quality setup is:

• 1080p webcam (or mirrorless camera)
• USB/XLR microphone
• OBS Studio
• Green screen or AI background removal
• Separate scene for intro → demo → call-to-action

If your demos are mostly SaaS/software walkthroughs, I’d lean toward OBS + a good mic for maximum quality, or ScreenFlow if you’re on Mac and want speed.

For your specific use case, I’d recommend Camtasia.

• Picture-in-picture webcam: You can record your screen and webcam simultaneously, then resize/reposition the webcam overlay. www.techsmith.com
• Green screen: Camtasia has a Remove a Color (chroma key) effect specifically for green-screen footage. www.techsmith.comobsproject.com
• Product-demo friendly: It records screen, camera, microphone, and system audio on separate tracks, which makes fixing mistakes and polishing demos much easier. www.techsmith.com
• Modern alternative to chroma key: It also has AI background removal, so you can remove your webcam background without an actual green screen. www.techsmith.com

Camtasia official site

If you want free

OBS Studio is the best free option. It supports webcam sources, picture-in-picture compositions, and a Chroma Key filter. The downside is that it’s much more hands-on and doesn't include Camtasia's built-in video editor. obsproject.com

My pick: Camtasia for polished SaaS/product demos; OBS if cost and maximum control matter more.

I wouldn't choose Screen Studio for this particular requirement: it's excellent for beautiful product demos on Mac, but its green-screen/chroma-key support has been a longstanding missing feature. screen.studio
