Test-Lab.ai Tunnel

Run Test-Lab.ai tests against localhost, staging, or VPN-only URLs by relaying traffic through your own browser.

Test-Lab.ai runs AI-powered browser tests in the cloud. Normally those tests reach public URLs. The Tunnel extension lets the same tests also reach URLs that only YOUR browser can see: your development server on localhost, a staging host behind SSO, or a corporate intranet inside a VPN, without opening any firewall. HOW IT WORKS 1. Install the extension and click "Connect". You sign in once with your Test-Lab.ai account and the extension stores a narrowly-scoped API key (tunnel-only: it cannot trigger test runs or read your project data). 2. When you kick off a test with tunnel mode enabled, Test-Lab.ai sends HTTP requests to this extension over an authenticated WebSocket. The extension performs each request from your browser and streams the response back. 3. Because the fetch happens in your browser, it hits whatever your browser can hit: localhost, VPN-only hosts, or SSO-guarded staging. WHAT WE WILL AND WILL NOT DO WITH YOUR BROWSER - We never attach your cookies. Every relayed fetch uses credentials: "omit", so Test-Lab.ai tests cannot read the session you are logged into. - We do not touch page DOMs, inject scripts, or read tabs. - We do not read clipboard, history, bookmarks, or any other browser data. - We only open a single WebSocket to www.test-lab.ai. That is the only outbound network activity the extension initiates on its own. PRIVACY No browsing data leaves your machine. The only data the extension sends to Test-Lab.ai is: - The API key you authorize (for authentication) - The responses to the specific URLs your test requests reach See: https://www.test-lab.ai/privacy FAQ Q: Does it work for HTTPS? A: Yes. For HTTPS targets we terminate TLS inside the sandboxed test runner using a synthetic self-signed cert; end-to-end TLS to the real origin is re-established inside your browser, so upstream certificates are never held or inspected by Test-Lab.ai. Q: Will my cookies leak into my test runs? A: No. Every relayed fetch is credentials:"omit". Q: Can I revoke access? A: Click "Sign out" in the extension popup. You can also revoke the API key from your Test-Lab.ai account settings.
