Oak builds a version control system for AI agents with virtual mounts

A version control system built for AI agents, not human patch reviewers, just shipped its first public build. Oak by Zach Geier replaces Git's full-repo-copy model with virtual mounts that let agents work on multiple tasks without downloading everything.

Four years of false starts, then 4 months with AI

Geier spent years building a VCS called Jam in his free time, sold it to a company that shut down, and kept thinking about what version control could be. He claims AI let him compress four years of effort into four months. Oak's open-source core and CLI are already bootstrapping themselves - the team uses Oak to build Oak, with no Git backup.

Virtual mounts for agent parallelism

Oak's headline feature: agents locally or in the cloud no longer need a full copy of a repo to start working. Virtual mounts present only the files needed for a given task. That means you can run many agentic workflows in parallel without fighting worktrees or blowing out disk space. oak serve handles self-hosting; oak export dumps your repo into a standard Git repository at any time.

Still early, already shipping

No Windows build yet. No CI, issues, or comments. But Geier and product designer Adam Morse are eating their own dog food. The first 100 paid subscribers get a personalized e-ink display with a unique Oak species (the shape unclear, even to them). Oak joins a growing list of tools rethinking developer infrastructure for AI-native workflows - but it's the first to take a swing at version control itself.
