Atlas is a desktop application for source control and shared context across coding-agent sessions, developed by Pacifio. It runs Claude Code, Codex, its native agent, and agents from the ACP registry against a codebase, recording prompts, tool calls, file changes, and patches in local session storage. When a commit is created, Atlas links it to the session that produced it, preserving those checkpoint relationships through rebases and amends and allowing the session to be queried later.
Before sending a prompt, Atlas resolves local @ mentions, combines project notes and agent memory, performs on-device semantic retrieval, and can add a handoff from a previous session. Markdown knowledge files, CLAUDE.md, AGENTS.md, plans, decisions, failures, file changes, skills, papers, and past sessions can therefore be shared between agents. The application also provides a code editor, Git operations and diffs, a terminal, a project knowledge base, research tools, a browser, spatial boards, and agent activity history.
Atlas is local by default: code, notes, and sessions remain on the machine, secrets are scrubbed before persistence, and local mode works without an account or network. Optional organisations can sync across devices and teammates. The repository states that macOS is the supported platform; Linux and Windows builds are untested. It is distributed under the MIT license.
