Test REST APIs directly in your browser. Send HTTP requests with custom headers, body, and auth — view status, response body, and headers instantly.
The API Tester is a lightweight Postman alternative that runs entirely in your browser. Send HTTP requests to any public API and inspect the response status, body, headers, response time, and size.
All requests are proxied through a server-side route. Requests to private IP ranges (10.x, 192.168.x, 172.16-31.x), localhost, and non-HTTP(S) protocols are blocked to prevent SSRF attacks.
