Why this tool stays in the browser

A small HTTP client for hitting local or public APIs from the page. Method, headers, and body are assembled in the browser. This is not a hosted request proxy: you are not parking secrets on rejisterjack.com. Use it to sanity-check status codes and payloads, then look up codes or build query strings in the neighboring tools.

FAQ

Does rejisterjack.com proxy my request?

No. The browser sends the request. CORS still applies. This is not a secret-storing hosted proxy.

Can I call localhost?

Yes, from this origin’s page to a local server that allows the browser. Headers and body stay in the tab.

Where do I look up status codes?

HTTP Status Codes in this sandbox — a reference, not a network call.
