ByteDance's enterprise-oriented generic proxy solution suite, fast and feature-rich.
Core Features
- Async Rust implementation for high speed and reliability
- Multiple proxy protocols: HTTP, SOCKS5, SNI, transparent proxy
- TLS man-in-the-middle interception and ICAP adaptation for security auditing
- Flexible egress route selection, load balancing, and failover strategies
- Granular ACL, rate limits, user authentication, and per-user site config
What It Can't Do
- •Reverse proxy (g3tiles) and NAT traversal are still WIP; not recommended for production use
- •Building requires Rust 1.90+ and TLS libraries (OpenSSL/BoringSSL/AWS-LC); ensure dependencies are installed
- •TLS interception features require proper CA certificate setup; ensure legal and ethical use
Use Cases
- Enterprise forward proxy with traffic inspection and access control
- Reverse proxy / load balancing for internal services (features under development)
