This utility is a high-performance node optimized for modern browser environments. All data processing is executed client-side, ensuring zero knowledge transfer to external servers.
Enter your API endpoint URL, select the HTTP method (GET, POST, PUT, DELETE), add any required headers and request body, then click Send. The formatted JSON response appears instantly.
Yes. Add Authorization headers (Bearer tokens, API keys, Basic auth) in the Headers section. Common headers like Content-Type and Accept are also supported.
Yes. Since the tool runs directly in your browser, it can make requests to localhost (e.g., http://localhost:3000/api/users) and local network addresses. No CORS proxy needed for local APIs.
Supports all standard HTTP methods: GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS. You can also send custom request bodies in JSON format for POST and PUT requests.
This tool works instantly in your browser with no installation, no account, and no configuration. Postman has more advanced features (collections, environments, tests), but for quick API testing, this is faster and simpler.
