REST Request Tester

Send simple REST API requests from your browser, inspect status, headers, timing, body previews, and copy a matching cURL command.

REST request workspace

Send browser requests directly and copy the matching cURL command.

Requests are sent directly from this browser to the URL you enter. Utilumo does not proxy, log, or store request details. Browser CORS rules still apply. QUERY is a newer safe HTTP method, so many servers will not support it yet.
Files are processed in your browser. No data is uploaded.

Questions

Does REST Request Tester send requests through Utilumo?

No. Requests are sent directly from your browser to the target URL. Utilumo does not proxy or store them.

Why do some API requests fail in the browser?

Browsers enforce CORS and mixed-content rules. If an API blocks browser requests, copy the generated cURL command and run it in your terminal.

Can it show response headers and JSON?

Yes. The tester shows status, timing, size, response headers, and prettifies JSON responses when possible.

Does Utilumo upload my input?

No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.

Do I need an account?

No. Utilumo tools are built to work without accounts or sign-in.
