What is Atlas used for?

Atlas is a workspace that works as source control for AI coding agents, linking commits to the sessions that produced them and letting several agents share one codebase and memory. It is a good fit for auditing what coding agents changed and why, comparing Claude Code and Codex on one repository, and keeping context when switching agents.

Is Atlas open source?

Yes. Atlas is open source under the Apache-2.0 licence. Its source code is on GitHub at pacifio/atlas and is written mainly in Rust.

Yes. Atlas is open source, so the software itself is free to use.

What are some alternatives to Atlas?

Similar open-source tools in the Developer Tools category include Munder Difflin, Storybloq and Agent Beacon. SaaS products in the same category include 1DevTool, AgenKit and Claude Code and Codex Assist.

Is Atlas actively maintained?

Yes. The most recent commit to Atlas was on 2 October 2026. The project has 8.7k stars on GitHub.

About Atlas

Atlas is a desktop workspace for coding agents, described as source control for agents. Every agent run produces checkpoints that link commits back to the session that created them, along with the prompts, tool calls and reasoning, so you can see which agent did what and why, even months later.

Claude Code, Codex, OpenCode, the built-in Atlas agent or any agent from the ACP registry can run side by side on the same codebase. Shared memory carries decisions from one agent to the next, so switching mid-task does not mean starting again. Notes in a knowledge folder and existing CLAUDE.md and AGENTS.md files feed every agent, and prompts can reference files, folders, symbols, branches, commits, notes and past sessions. Code, notes and sessions stay local by default, with optional sync for a team.

Atlas is written in Rust with Tauri, licensed under Apache-2.0, and was created in May 2026, so it is in alpha. Builds are provided for macOS 13 or newer, with Apple Silicon or Intel, and for Windows 10 on x64.
