## What it is
anytls-go is the Go reference implementation of the AnyTLS protocol, a proxy protocol designed to mitigate TLS-in-TLS nested handshake fingerprinting. It provides example server and client binaries with flexible padding, connection multiplexing, and a simple configuration, while production users are directed to third-party clients like sing-box and mihomo.

## Use cases
- hide TLS-in-TLS proxy handshake fingerprints from DPI
- run a lightweight proxy server to tunnel traffic
- set up a socks5 client proxy over an AnyTLS server
- reduce proxy latency via connection reuse
- implement the AnyTLS protocol in another proxy client
- test protocol edge cases and padding strategies

## When to choose
- you need the canonical reference implementation of the AnyTLS protocol
- you are building AnyTLS support into a proxy client like sing-box or mihomo
- you want to experiment with anti-fingerprinting proxy protocol design
- you need a simple self-hosted proxy to evade TLS-in-TLS detection

## When to avoid
- you need a polished production-ready proxy client for daily use
- you require guaranteed protection against TLS man-in-the-middle attacks, since default example configs are insecure
- you need a proxy protocol with broad existing ecosystem support outside sing-box/mihomo-compatible clients
- you need a license-clarified deployment in a commercial context, as no license is specified
