Overview

HTTP Toolkit is an open-source tool for debugging and testing HTTP(S) on Windows, Linux and Mac. It intercepts traffic from targeted clients — individual Android or iOS apps, Docker containers, browser windows, terminal sessions and backend processes — or accepts any client configured to use it as an HTTP proxy. Captured messages can be filtered, inspected, paused with breakpoints and edited, and you can send your own requests.

Best for: Developers and testers who need to intercept, inspect and edit HTTP(S) traffic from specific clients.
Pricing: Free Hobbyist tier, then Professional at £7 per month and Team at £11 per user per month, both plus local tax; a yearly option is advertised as 25% cheaper but no annual figures are shown.
Runs on: AndroidmacOSWindowsLinux
