AI product readChrome extension bridge/proxy that allows the ReqBin web app (reqbin.com) to send HTTP requests to localhost and local network servers through the user's browser
Web apps running in browsers cannot directly access localhost or local network servers due to browser security restrictions (mixed content, CORS). This extension acts as a proxy bridge, receiving commands from the ReqBin web app and executing fetch() calls to any URL including localhost, returning the responses back to the web app.
User installs the extension, then navigates to reqbin.com. From the ReqBin web interface, they configure an HTTP request targeting localhost or a local network server. The web app sends a message to the extension via chrome.runtime.sendMessage. The service worker validates the sender origin (reqbin.com domains), parses the request payload (method, URL, headers, auth, content), and executes a fetch() call. The response (status, headers, body, timing) is sent back to the web app for display.

- Target users
- Web developers testing APIs running on localhost or local network servers / Backend developers debugging local HTTP services / QA engineers testing local development environments
- Cannot determine whether reqbin.com itself requires login for its web interface — the extension code reveals nothing about the web app's auth requirements
- Cannot determine if reqbin.com has paid tiers that affect available features in the web app that commands this extension
- The extension has <all_urls> host permission but only accepts commands from reqbin.com domains — the actual network request targets are controlled by the web app
MonetizationNo paid features detected
The extension contains no paid feature gating, no subscription checks, no billing APIs, no payment platform integrations, and no upgrade prompts. The 'upgrade' keyword hit on utils.js:128 is the HTTP 'Upgrade' header in the forbidden-headers list — an HTTP protocol concept, not a paid upgrade. The 'pro' keyword hit in _metadata/verified_contents.json is a base64 hash of file contents, not a pro-tier reference. The extension is a pure proxy/bridge with a single fetch function — no feature differentiation.

- No
- Reason
- The extension itself has no login UI, no account system, no authentication tokens, and no login flow. All 'auth' references in the code (utils.js lines 21-87, fetchRequest.js lines 49-57) handle HTTP Authorization headers (Bearer Token, Basic Auth, Custom Auth) for the API requests being tested — not extension login. The service-worker.js only checks sender origin (reqbin.com domains) via 'Unauthorized sender' check, not user authentication. The popup.html simply links to reqbin.com with no login prompt. The destination service (reqbin.com) may require its own account, but the extension itself does not gate any functionality behind login.
Just blocks you after only a couple requests. Useless now.
Well, since they changed to cloudflare or whatever they did now it just blocks me. All I did was a couplre requests then hit help and blocked. This used to be a great site.
Very useless...
Very good!
This site and extension were super helpful for testing out pieces of code I was using to try to create a LaMetric TIME app so the school I work for could use our smart clocks as an emergency alarm system, but I've been blocked for some reason that I'm sure is beyond what I understand about coding. The page that tells me I'm blocked from ReqBin says I should email the site owner and include my Cloudflare Ray ID to try to gain access back, but I can't find the owner's details anywhere. Hoping this review will somehow get back to the site owner so I can keep using this site for work! Cloudflare Ray ID: 7a7f6ae86f067fe7
How can I select ReqBin Chrome Extension as the server node at https://reqbin.com ?
¡Muy util!
I have added extension, set EXT and got this error: ReqBin Chrome Extension Cannot set the header: method With US or DE it works well. What should I do?
Comodissima. Permette di fare tutto da browser anche verso gli indirizzi locali.
when you cba using curl to test your apis just use this
