Atlas: Source Control for Multiple Coding Agents

TL;DR: Atlas is a Rust-based CLI that gives you one working copy across multiple AI coding agents. Spin up Claude Code, Codex, and other agents against the same project, track which agent changed what, and query their history from a single place.

What it is

pacifio/atlas calls itself “Source control for agents”. The description continues: “Use multiple coding agents, track their changes and query them in one place.” The repository has 4,647 stars and 281 forks at the time of writing, with topics covering ai, ai-coding-assistant, claude-code, codex, and coding-agents. The default branch is main, the language is Rust, and the homepage links to https://www.tryatlas.cc/.

It was created in May 2026, which places it firmly in the post-Claude-Code category of developer tooling that grew up alongside agentic workflows.

What it does well

Atlas addresses a problem that only appears once you have more than one agent running on the same project: how do you keep their changes from stepping on each other?

• Per-agent working copies. Each agent gets an isolated workspace, so you can run Claude Code on a feature branch while Codex works on a refactor without overwriting each other.
• Change tracking. Atlas records which agent produced which diff, so when something breaks you can ask “which agent touched this file?” without reading the whole git log.
• Unified query. A single command surface lets you inspect agent state, switch contexts, and roll back specific changes without juggling multiple terminals.

Because the core is written in Rust, startup is fast and the binary is a single static executable — useful when you want to install Atlas on a remote build host without dragging in a runtime.

How to try it

The project is brand-new enough that the README is the canonical install guide, but the homepage at https://www.tryatlas.cc/ is the most current reference. Once installed, the basic loop is:

atlas init                          # set up an Atlas workspace in the current repo
atlas agent add claude-code         # register an agent
atlas agent add codex
atlas run claude-code "add retries"
atlas run codex "refactor config"
atlas diff claude-code              # see what each agent changed

Configuration lives in .atlas/ at the root of your project, so it co-exists with your existing git workflow rather than replacing it.

When it fits, and when it doesn’t

Atlas fits a workflow where you already orchestrate multiple agents against a single repository and you have started losing track of which agent changed what. It is less useful when you only run one agent at a time or you are happy letting that agent commit directly to a single branch.

There is also a maturity caveat: the repository was created in mid-2026, so the API and configuration format may still shift. If you adopt Atlas today, plan to read release notes when upgrading.
