SwiftlyS2 for CS2 — a lightweight C# plugin framework

[CS2] SwiftlyS2 — a high-performance C# plugin core for CS2

Software type: lightweight, fast server framework.

Plugin language: C# (.NET). Fully migrated from Lua to C#.

Dependency: standalone mode or installation on top of MetaMod:Source.

Main feature: a native C++ core combined with C# scripts.

SwiftlyS2 is a modern, complete and independent alternative to other server engines in Counter-Strike 2. The framework's main advantage is flexible integration: it can run fully on its own (standalone) directly with the game engine, or as a classic MetaMod:Source plugin.

🚀 Key features:

Highly optimized: minimal RAM usage and very low CPU load on the game server.

Developer-friendly: hot reload support and built-in memory leak protection.

Advanced features: an API for entities, low-level memory hooks, protobuf messages and game menus.
