Test REST APIs directly in your browser

A lightweight in-browser REST client for testing API endpoints. Send GET, POST, PUT, and DELETE requests with custom headers and request bodies. Inspect response headers, status codes, and JSON responses — no software installation required.

Frequently Asked Questions

Is this similar to Postman?
Yes. It is a lightweight browser-based alternative to Postman for quick API testing without installing any software or creating an account.
Can I send authentication headers?
Yes. Custom headers including Authorization (Bearer tokens, API keys, Basic auth) can be added to any request.
Does it support CORS?
Requests are proxied through the ProDevTools backend rather than sent directly from your browser, so CORS restrictions on the target API don't apply — you can test APIs that don't set Access-Control-Allow-Origin headers.
Can I import a curl command?
Yes. Paste a curl command into the "Import from cURL" panel and click Run cURL — it parses the method, URL, headers, and body (supports -X, -H, -d/--data, -u, and more) and sends the request immediately.
Can I send a JSON request body?
Yes. For POST, PUT, and PATCH requests, you can specify a JSON body and set the Content-Type header to application/json.
