BoltConn
BoltConn

GitHub Actions License: GPLv3 Release

A go-to solution for transparent application proxy & firewall with tunneling and MitM, designed with privacy and security in mind. All efforts made to make you fully control your network. Experimental webui & desktop client is available in XOR-op/BoltBoard.

Features

  • Fine-grained Traffic Control: Allow VPN-style global control, or dedicated http/socks5 per-inbound control.
  • Rule-based Blocking: Block ad/tracking traffic on a per-process/per-website/flexible way.
  • Rule-based Tunneling: Flexible way to tunnel traffic through http/socks5/wireguard/etc outbounds. Able to use compatible rules from similar community.
  • Audit Traffic: Audit traffic history by accessing API or dumping into SQLite.
  • Modify HTTPS Data: Manipulate requests and responses inside HTTPS traffic to redirect, block or modify them. Support injecting Javascript now.

For the full features, see features.md.
