Code Snippet

A REST client that is just a web page

Set a method and URL, add query parameters, headers, a JSON or form body and an auth scheme, then send. You get the status code, the response time, pretty-printed JSON, the raw body and the response headers — plus a ready-to-paste cURL, JavaScript fetch or Python requests snippet for the exact request you just built.

Two things to know

Requests go directly from your browser to the target, so they are subject to that server’s CORS policy. An API that does not send Access-Control-Allow-Origin will fail here even though the same request works from a terminal — in that case, copy the cURL snippet and run it locally.
Nothing is proxied through a server here, so any token or password you type goes only to the URL you entered, and is never stored.

Handy as a lightweight stand-in for Postman or Insomnia when you just need to poke an endpoint and get working code out of it.
