What is REST API Tester?
A REST API tester lets you send HTTP requests (GET, POST, PUT, DELETE, PATCH) to any API endpoint directly from your browser. You can set custom headers, compose request bodies, and inspect formatted responses with status codes, response time, and size.
This tool runs entirely in your browser — no data is sent to our servers. It's ideal for quick API testing, debugging webhooks, and verifying endpoint behavior during development.
