Common questions about REST Client
Yes, everything runs in your browser. Requests go directly from your browser to the API endpoint. Nothing passes through our servers. Your API keys, tokens, and request data stay entirely on your machine.
Browsers block cross-origin requests by default. The API server must include CORS headers (Access-Control-Allow-Origin) to allow browser requests. Try using a CORS proxy for testing, or test APIs that already support CORS.
Yes! Since everything runs client-side, you can test APIs running on localhost or any local network address. This makes it ideal for local development and debugging.
Currently the tool supports JSON and text body types. File upload support is coming soon. For now, you can send base64-encoded file content in the request body.
