Why use
Full MITM proxy via mitmproxy with TLS 1.3 support. Inspect every request and response — headers, body, timing, and client IP — in real time.
Pause flows mid-flight and modify the method, URL, headers, or body before they reach the server. Resume or drop — you're in full control.
One-click ADB setup: system CA install, proxy config, and Frida server push. Universal SSL unpinning so you can inspect any app's traffic.
No subscription, no account, no usage limits. A full alternative to Proxyman and Charles Proxy — completely free, forever.
The story behind
Dolly Proxy was built out of frustration with the cost of professional HTTP debugging tools. Proxyman and Charles Proxy are excellent — but they're paid, and not everyone should need a subscription just to inspect network traffic.
The goal is simple: a free, open-source alternative that doesn't compromise on features. HTTPS interception, request editing, Android device support, SSL unpinning — all of it, at no cost.
Built with Flutter for the UI and Python + mitmproxy for the proxy engine. The two communicate over WebSocket in real time. All traffic stays entirely on your machine — nothing is ever sent anywhere.
macOS, Windows, and Linux from a single Flutter + Python codebase
All traffic is intercepted and processed on your machine — never sent to any server
One-click device setup via ADB, with Frida-based SSL unpinning for any app
Built with
Google's cross-platform framework with Dart and Riverpod. One codebase for macOS, Windows, and Linux.
The proxy engine runs as a Python child process using mitmproxy and asyncio — handling all HTTPS interception and TLS termination.
Flutter and the Python proxy communicate over a local WebSocket connection, streaming flows to the UI in real time with minimal latency.
Android device management via ADB and universal SSL unpinning via Frida — automatically downloaded and configured on first use.
