GitHub Sponsors Profile

Most of the time, for HTTP Toolkit users, the best way to support HTTP Toolkit is to sign up for a Pro account at https://httptoolkit.tech/get-pro/ (this doesn't mean giving up on open source: all the Pro code is open source too!)
If you just want to fund the project as directly & efficiently as possible though, or if you're interested in funding to support development of the other open-source libraries & components rather than HTTP Toolkit itself, then you're in the right place!
All funds donated here go towards development of:

HTTP Toolkit development and core components
The many standalone libraries released as part of HTTP Toolkit, including:

Mockttp
React-Reverse-Portal
The Frida interception & SSL unpinning scripts for iOS & Android
The reusable encoding packages (http-encoding and brotli-wasm)
The OS proxy detection packages (os-proxy-config, mac-system-proxy and windows-system-proxy)
Browser-Launcher
JVM-HTTP-Proxy-Agent
Docker-Socks-Tunnel
Mobx-Shallow-Undo
(And many more to come in future)

The many open-source contributions made as part of HTTP Toolkit development to 3rd party open-source dependencies. Some representative examples (of hundreds):

Adding support for dynamic ALPN negotiation to Node.js
Fixing HTTP/2 bugs in Node.js
Reducing TLS fingerprintability of OpenSSL TLS handshakes
Improving Rust's TLS certificate configuration in Rustls
Improving WebSocket error & shutdown handling in the ws node package.
Fixing denial-of-service vulnerabilities in the dns2 node package
Many improvements to code generation in HTTPSnippet.

If any of that is valuable to you, sponsoring and supporting this ongoing work is much appreciated ❤️
