Send a request above to see the response here.
This HTTP Client lets you construct and fire HTTP/HTTPS requests using the browser's native fetch API — no extensions, no installs, no backend. It is ideal for quickly testing public APIs, inspecting response structures, experimenting with auth headers, and generating cURL commands you can paste directly into any terminal or container shell.
Browsers enforce the Cross-Origin Resource Sharing (CORS) policy: if a server doesn't explicitly allow your origin, the browser will block the response even though the request was sent. This is not a limitation of this tool — it's a security feature of every browser. The generated cURL command bypasses CORS entirely because it runs outside the browser, making it the perfect companion for container shells or CI pipelines where you can't install Postman.
Your request history is stored exclusively in localStorage in your own browser. Nothing is transmitted to any server. URLs, headers, auth tokens, and body payloads never leave your machine.
