Versi

Versi is a source control system built for the way software is starting to get made with AI agents. Git works well when a human edits code, stops, commits, and pushes. Agents do not work that way. They run in temporary sandboxes, get killed mid task, work across machines, and often make useful progress before there is a clean commit. Versi separates preserving progress from declaring meaning. Every saved file change can be recorded into a durable line of work, so an agent workspace can disappear without losing the work. Later, a human or agent can create checkpoints, run validation, compare approaches, and promote only the change that is ready. Our hackathon prototype shows the core primitive working end to end. We track saved file changes, sync them across separate local workspaces, create lines of work for parallel attempts, validate a checkpoint, rewind to a good state, promote the result to main, and resume from a fresh workspace through a remote store. The goal is not to replace Git for everyone. The goal is to build source control for parallel human and agent work, where workspaces are disposable but the work is not.
