Mega

Mega is an open source, Rust based version control and monorepo engine presented as a repository system for AI agents. The project describes itself as an open source implementation of the Piper model, the large single repository approach used internally at some large companies. The site is written in Chinese. The design is distributed, with graph state spread across a connected mesh of agents so there is no single point of failure. It stays compatible with Git. A virtual file system loads files on demand through FUSE, so repositories with millions of files can be opened in milliseconds without cloning them in full. For agent use, Mega generates a native vector representation for each commit, and agents can query a repository semantically through its command line interface. The intended users are teams that maintain very large monorepos or want coding agents to explore repository history by meaning rather than by text search. A quick start is offered through a Docker Compose demo file, and the project lists its source on GitHub. The site does not publish pricing, and the project is described as open source.
