HTTP Request Tester
Send real HTTP requests with custom methods, headers, and bodies. Inspect status code, response time, headers, and pretty-printed JSON. Subject to browser CORS rules. Runs in your browser.
About HTTP Requests
Sends real HTTP requests from your browser. Requests are subject to CORS: servers without permissive Access-Control-Allow-Origin headers will be blocked. For status code reference see HTTP Status Codes.
Secure & Private Client-Side
This tool runs entirely in your browser. No data is sent to any server, ensuring your information remains private and secure.

Frequently Asked Questions
Why do some requests fail with CORS? expand_more
Browsers enforce Cross-Origin Resource Sharing. If the server does not return an Access-Control-Allow-Origin header that permits your origin, the browser blocks the response.
Which HTTP methods are supported? expand_more
GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS. The body field is disabled for GET and HEAD which must not include a body.
Can I send authenticated requests? expand_more
Yes. Add an Authorization header (for example "Bearer token") in the request headers area. The token stays in your browser.
What does the status color mean? expand_more
2xx green for success, 3xx blue for redirection, 4xx amber for client errors, 5xx red for server errors. Cross-reference codes in the [HTTP Status Codes](/tools/http-status-codes/) reference.
Are my requests private? expand_more
Yes from this tool; no from the destination server. The tool sends your request directly to the URL you enter, so only use endpoints you trust.
Common Use Cases
- API Testing: Hit REST endpoints and inspect raw responses.
- Webhook Debugging: Replay a payload to a webhook receiver.
- CORS Checks: See whether a server exposes CORS headers.
- Performance: Measure response time for slow endpoints.
