APIVoid Request Tester — APIVoid

Send and test HTTP API requests directly from your browser, with full control over headers, body, and method.

Five request body formats:

• None - for GET, HEAD, and other body-less requests
• JSON - pretty input with automatic Content-Type
• Form-urlencoded - for classic form submissions
• Raw text - send any payload as-is
• Custom headers - add, edit, and remove headers freely

Save any request as a named profile and re-run it later with a single click. All seven HTTP methods are supported (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS).

Inspect responses with status code, total time, payload size, full response body (JSON is auto-formatted and syntax-highlighted), and a complete response headers table. Copy or save the body and headers to a file in one click.

No uploads, no external servers, no telemetry, everything runs locally in your browser. Saved profiles live only in your local extension storage.

Very simple to use:

• Click the pinned icon on the toolbar
• Enter a URL, pick a method, add headers or a body if needed
• Click "Send Request" to see the response
• Click "Save Profile" to store it for later
• Re-run any saved profile from the "Saved Profiles" tab

Built for developers who frequently test API endpoint.
