VERSY v0.3.0 preview

VERSY · Native version control · Open source

AI-first version control
for an agentic world.

VERSY is a brand new version control system built from the ground up in Rust for autonomous software development. It is not a Git wrapper.

Give people and agents durable memory of their work: exact code, parallel attempts, recorded checks, and the reasons behind decisions.

An AI agent swarm working with VERSY: a planner organizes Changes; three builders work in separate Runs and Workspaces; a reviewer inspects Checkpoints and Evidence; an integrator combines Candidates through Integration into main.

Let agents explore.
Keep what they learn.

Explore in parallel

Give each attempt its own workspace. Let agents try different approaches while keeping failed and rejected work available to learn from.

Carry context forward

Help the next person or agent pick up the thread with exact code snapshots, recorded intent, and an inspectable history.

Choose with evidence

Attach test results to the code they checked. Compare candidates and record why a result was chosen.

A different model for software work

How VERSY compares with Git.

Both record source history. VERSY also makes development attempts, checks, and selection decisions explicit parts of that history.

AreaVERSY 0.3.0Git
Source historyIts own object store: Blobs, Trees and Checkpoints, with append-only workflow Events.Content-addressed blobs, trees and commits, referenced by branches and tags.
Parallel workA Change describes the objective; Runs use isolated Workspaces and produce Candidates.Branches name lines of work; linked worktrees provide separate working directories.
Checks & reasonsEvidence records checks against exact Checkpoints. Rationale and selection records retain the reasons and criteria.Commit messages and notes retain context. Testing and review workflows can be added through other tools.
RemotesExperimental local preview. VersyHub remotes and shared collaboration are under construction.Distributed workflows with remotes, clone, fetch and push.

Evidence records what a tool or actor reports; it is not proof of correctness. See the VERSY workflow and current release scope.

VersyHub

A home for VERSY remotes and shared collaboration. Under construction; remote hosting is not available in this release.
