Scn

Scn is a scalable source control system written in Rust with Git-style commands and an HTTP API for agents.

Scn is a scalable source control system built in Rust and inspired by Scion. It features stateless controllers, SQLite shards, and Valkey and S3 storage to handle large datasets and monorepos. The system offers Git-style CLI commands and an HTTP API designed for agents to make server-side commits without a local checkout. Large files automatically use deduplicated Zstandard chunks. It supports Linux and macOS platforms.
