Invoker

Minimal HTTP client for developers. Send GET, POST, PUT, DELETE and HEAD requests with custom headers, body, and saved requests.

Invoker is a lightweight HTTP client that lives in your browser toolbar. No separate app, no account, no setup — just open the popup and start firing requests. Features - Send GET, POST, PUT, DELETE and HEAD requests to any URL - Add custom request headers with a simple key/value editor - Include a request body for POST and PUT requests - View the full response — body (auto pretty-printed for JSON), status code, response time, size, and response headers - Save requests locally and restore them in one click - Dark and light theme Built for developers Invoker is designed for quick API testing during development. No tabs to manage, no projects to organize — just a fast, focused tool that gets out of your way. Privacy All saved requests are stored locally in your browser. No data is sent to any external server. Ever.
