ninenines/ranch

Ranch is an Erlang library for building TCP, UDP, and SSL/TLS network servers. It provides a robust framework for managing network connections, including listener lifecycle, connection handshakes, and transport-level protocols. The system supports both gen_server and gen_statem-based protocol handlers, offering examples for common patterns like echo and reverse services. It includes comprehensive documentation and an expanded test suite covering connection management, SSL/TLS upgrades, and concurrency safety.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 70ae2ff5d5 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
