How it got here

2015–2020 · v1 architecture and observability overhaul

This period focused on a comprehensive architectural overhaul, introducing a new v1 configuration schema, a v2 wire protocol, and a centralized control manager for robust proxy lifecycle management. The team significantly enhanced observability by implementing Prometheus metrics, in-memory tracking, and structured logging, while also adding health checks and port management. Additionally, the project established a modern CI/CD infrastructure and a robust end-to-end testing framework to support these complex changes.

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 2291e8835f — 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.
