HTTP Toolkit 1.25.2 for Linux

HTTP Toolkit is a tool for testing, debugging & developing with HTTP and HTTPS.

If you're looking to develop, test, or debug HTTP traffic, you're in the right place.

Features

With HTTP Toolkit, you can:

• Instantly intercept browsers, most backend & scripting languages (from Node.js to PHP), Android devices, Electron apps and more with one-click setup.
• Collect interesting traffic without intercepting everything on your whole machine, so there's no extra noise and no side-effects - just the traffic you care about.
• Inspect the full headers & body for every request & response from every client, to immediately see what's really being sent & received on the wire.
• Easily understand collected HTTP traffic, with inline documentation for all standard headers & response statuses, plus body decoding, highlighting, folding, and other niceties, powered by the same internals as Visual Studio Code.
• Send HTTP requests, with a fully featured HTTP client to send your own custom requests, or resend (and tweak) requests intercepted from other clients
• Quickly find the data you care about, with exchanges highlighted by the type of client and tagged by category (images, JSON responses, errors), and free-text & structured filtering across all request & response data.
• Breakpoint live requests or responses, to rewrite HTTP traffic on the fly.
• Mock endpoints or servers, with flexible rule configurations to match and handle requests automatically, to send responses, inject failures & timeouts, or transparently redirect requests elsewhere.
• Intercept any HTTP traffic: HTTP Toolkit is a transparent HTTP proxy, and can intercept plain HTTP, encrypted HTTPS, WebSockets, HTTP/2, proxy requests, direct requests, manually redirected packets, you name it, all on one port.
