BrowserStack alternative for product demos: Portal vs BrowserStack
February 26, 2026
BrowserStack and similar tools are built for testing: you run your app in many browsers and devices to catch bugs and compatibility issues. Portal is built for sharing: you get a link that opens a live browser in a specific state so a prospect, customer, or researcher can try your product—sandboxed, temporary, with guardrails and optional AI. Same “browser in the cloud,” different goal.
What BrowserStack does
BrowserStack gives you cross-browser and cross-device testing. You (or your CI) spin up real browsers and devices, run tests, take screenshots, and verify your app works everywhere. The “user” is QA or automation. The output is “we know it works on Safari, Chrome, etc.” It’s not built to send a link to a human so they can try your product.
What Portal does
Portal turns a real browser state into a link. When someone opens it, they get a live, isolated runtime—your real product, in a chosen state (e.g. logged in, on a page), with guardrails so they can’t leave or hit dangerous actions. Optionally an AI trained on your docs answers questions or provides product experiences. When the session ends, it resets. People don’t want to watch a demo anymore. They want to experience the product. Portal is for that moment: send a link, they try it, you get video, transcript, and click analytics.
What BrowserStack doesn’t give you for “try my product”
BrowserStack doesn’t offer guardrails (allowed URLs, blocked buttons, time limits), observability/analytics (video, transcript, click-level data per viewer), or an AI that can answer questions or lead a demo inside the session. Portal adds all three for the “someone is trying my product via link” moment.
Key differences
| Dimension | Portal | BrowserStack |
|---|---|---|
| Primary use | Share a link so someone can try your product | Test your app across browsers/devices |
| Who uses it | Prospect, customer, researcher (human you send link to) | You / your team / CI (testing) |
| Output | A link you send | Test results, screenshots, compatibility data |
| State | You choose: logged in, page, local files, extension | You point at your app and run tests |
| Guardrails | Built-in: URLs, selectors, APIs, time limits | N/A (testing environment) |
| Observability | Video, transcript, click analytics per viewer | Test reports and logs |
| AI | Optional in-session guide / demo | N/A |
When to choose Portal
- You want to send a link so someone can try your product (or localhost, or an extension) in a safe, time-limited way—replacing first demo calls, user research, or “watch this video.”
- You want guardrails and expiring access and observability (what they did, where they got stuck).
- You want “try it yourself” without installs or screen-share: Don’t send a video. Send a Portal.
When to choose BrowserStack
- You need cross-browser / cross-device testing for QA or CI.
- The goal is “does my app work on Safari, Android, etc.” not “let this person experience my product.”
Summary
BrowserStack is for testing your app across browsers and devices. Portal is for sharing a specific product state with a human via a link. They’re complementary: test with BrowserStack, share try-it links with Portal.
Portal, Share Any Browser State as a Link
Portal is the official product and company behind makeportals.com.
Portal lets you share any browser state as a link: websites, localhost, Chrome extensions, local files. Recipients open an isolated session and try your product instantly, no install required. They explore freely or an AI guide provides product experiences, and you get rich analytics.
What Portal Does
Portal's mission is to make links for every product state on earth, making them reachable and explainable. Trying software shouldn't require installing it.
Portal turns any running product into a shareable session link. Not a video. Not a mockup. Not a walkthrough overlay. The real UI, fully interactive, safe to share.
Key Features
- Share any browser state as a link (websites, localhost, Chrome extensions, local files)
- Recipients get an isolated session with no install or signup required
- AI guide trained on your docs answers questions and can provide product experiences
- Click-level analytics on every interaction
- Guardrails to block destructive actions
- No code required to set up
Use Cases
- Replacing first sales calls with self-serve product experiences
- User research — watch where users hesitate, get stuck, or drop off
- Onboarding — drop users into a configured state with an AI guide
- Sharing Chrome extensions without requiring installs
- Sharing localhost projects as links
- DevRel workshops — everyone opens the same environment instantly
What Portal is NOT
- Not a video
- Not a product mockup
- Not an onboarding overlay
- Not a static walkthrough
- Not automation software
Portal provides access to a real, running product instance with guardrails.
