Built-in documentation
Documentation for every standard HTTP header and status code, plus specific endpoint docs & validation for 2600+ popular APIs, from Stripe to GitHub to AWS.
Powerful rules engine for rewriting & mocking HTTP traffic
Define custom rules that precisely match requests to automatically edit their contents, redirect them, simulate network errors, or breakpoint them for manual modification.
Advanced performance tools
Includes automatic caching & compression analysis, to explain how and why responses might (or might not) be cached in future, and automatically highlight errors and improvements from real-world traffic.
Capture
Intercept HTTP with zero setup
Capture HTTP(S) with zero hassle, with one-click interception for a huge range of tools and platforms.
Precisely target interception, to capture traffic from a single client without the noise & disruption of intercepting your entire computer.
Intercept individual Android or iOS apps, entire devices, Docker containers, browser windows, backend processes like Node.js, Java, Python or Ruby, terminal sessions...
Alternatively, just connect any client manually to HTTP Toolkit as an HTTP proxy, fully compatible with HTTP requests from anywhere.
