REST Client

Send HTTP requests (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS) directly from the browser; import a curl command to fill in method, URL, headers, auth, and body in one step; configure environment variables, auth presets, headers, query params, and body; includes a built-in WebSocket client.

Requests run from your browser. If the API blocks cross-origin requests (CORS), the request is retried through our server and marked 'via server'. Localhost and private addresses only work from your browser.

Frequently asked questions

Is my data uploaded to a server?

That's this tool's whole purpose — it sends the request you build to whatever endpoint (HTTP or WebSocket) you specify. Nothing else about your usage is sent anywhere.

How do I import a curl command?

Paste a curl command and the tool fills in the method, URL, headers, auth and body in one step.

Why do I get a CORS error?

Requests are sent from your browser first, so the target server must allow cross-origin requests. If the browser call fails, public endpoints are retried automatically through a backend request proxy, and the response is marked as sent via the server.

Can I test a WebSocket?

Yes, the WebSocket tab provides a built-in WebSocket client.

Can I use environment variables and auth presets?

Yes, you can define environment variables such as a base URL and API keys, and use auth presets like Bearer or Basic.

Which HTTP methods are supported?

GET, POST, PUT, PATCH, DELETE, HEAD and OPTIONS.
