Burrow

Burrow is an open source tool for burrowing through firewalls, built by teenagers at Hack Club.

burrow provides a simple command-line tool to open virtual interfaces and direct traffic through them. Routine verification now runs unprivileged with cargo test --workspace --all-features; only tunnel startup needs elevation.

The repository now carries its own design and deployment record:

• Constitution
• Agent Instructions
• Burrow Evolution
• WireGuard Rust Lineage
• Protocol Roadmap
• Forward Email Runbook

Contributing

Burrow is fully open source, you can fork the repo and start contributing easily. For more information and in-depth discussions, visit the #burrow channel on the Hack Club Slack, here you can ask for help and talk with other people interested in burrow. Checkout GETTING_STARTED.md for build instructions and GTK_APP.md for the Linux app. Forge and deployment scaffolding live in flake.nix, nixos/, and .forgejo/workflows/. Hosted mail backup operations live in docs/FORWARDEMAIL.md and Tools/forwardemail-custom-s3.sh.

Agent and governance-sensitive work should start with AGENTS.md, CONSTITUTION.md, and the relevant BEPs under evolution/proposals/. Identity and bootstrap metadata now live in contributors.nix.

The project structure is divided in the following folders:

Apple/ # Xcode project for burrow on macOS and iOS
