Lithos is a compatibility-first, high-performance server-side fork of Vintage Story.
The project starts from the current vanilla server and applies focused, measured optimizations while preserving the behavior expected by stock clients and ordinary mods. Correctness, save safety, and compatibility take priority over performance.
Lithos currently targets Vintage Story 1.22.7 and is in active development.
- Reduce CPU time, allocations, and server operating cost in proven hot paths.
- Preserve vanilla member shape, initialization order, save data, packets, and observable behavior.
- Keep changes small enough to review, measure, and rebase as Vintage Story evolves.
- Maintain one reproducible source layout across Windows, Linux, and macOS.
Network statistics are reported by participating Stratum and Lithos servers.
Lithos uses Stratum as a source of performance ideas, not as a code baseline. Each change starts from vanilla and must justify its compatibility surface.
