Does this send real HTTP requests?
Yes. Requests are fired directly from your browser using the Fetch API. The response you see is the actual response from the server.
Why does my request fail with a CORS error?
Browsers block cross-origin requests unless the server includes the appropriate CORS headers. APIs that are not designed for browser access will be blocked. Use a server-side proxy or a CORS-enabled endpoint to work around this.
Is my request data sent to devtoolsforyou servers?
No. Requests are sent directly from your browser to the target URL. No data passes through our servers.
What HTTP methods are supported?
GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS are all supported.
