Reason Machines · Agent Git Server

Aspen

Aspen is an open-source, self-hostable Git server written as a single Rust binary, built for repositories that many AI agents push to at once. It scales writes per branch rather than per repository, stores branch history in PostgreSQL or SQLite and packs in S3-compatible object storage, and works with stock Git over HTTPS and SSH. Self-reported results on one 8-core server show 567 pushes per second sustained for five minutes, with 314 ms p99 push latency, but the project is pre-alpha and the 24-hour durability gate is not yet met. It is licensed under Apache 2.0 and described as an independent implementation of the design OpenAI described for Pando.
