v2ray/v2ray-core
This system is a modular proxy and tunneling platform that manages inbound and outbound connections through a pluggable architecture of protocol handlers. It provides comprehensive network routing, traffic statistics, and configurable policy enforcement, while supporting a wide variety of transport and proxy protocols. The system also includes a robust configuration management layer that supports multiple formats and remote loading, alongside extensive tooling for diagnostics and service control.

How it got here
2015–2016 · Core architecture and protocol expansion
This period focused on a comprehensive architectural overhaul, introducing structured configuration loading, a new logging and error handling infrastructure, and a modular proxy interface. It also expanded the project's capabilities by adding support for multiple transport protocols (XTLS, WebSocket, QUIC) and proxy types (Socks, MTProto, BlackHole, Dokodemo), while simultaneously removing obsolete components like the old JSON config unmarshaller and VMess handler.

2017–2018 · API expansion and transport diversification
This period focused on exposing the core's internal capabilities through a new gRPC-based management API, enabling external tools to control proxies and monitor statistics. Simultaneously, the codebase expanded its transport layer to support HTTP/2, QUIC, Domain Sockets, and various header obfuscation techniques, while introducing modular configuration loading and structured logging.

2019–2020 · Protocol and configuration expansion
This period focused on expanding the proxy ecosystem by introducing support for VLESS and Trojan protocols, alongside a new DNS outbound proxy. The team also overhauled the configuration system with JSON support and improved error reporting, while adding diagnostic tools and systemd service units to enhance usability and management.

v2ray/v2ray-core was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
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 29 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit d80440f3d5 — 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.
