Atlas

Atlas is a desktop workspace for developers who use coding agents across projects and want to keep the context behind their code changes. It brings agent conversations, code review and project history into one window.

• Parallel agents: Run Claude Code, Codex, OpenCode, Atlas's own agent or other ACP agents concurrently, and steer individual sessions while the others continue.
• Session history: Review captured prompts, responses and tool calls, ask questions about past sessions, and trace commits back to the agent runs that produced them.
• Project context: Give agents files, branches, commits, notes and earlier threads as context, with local semantic retrieval across project knowledge and agent memory.
• Code review and editing: Edit files, use terminals, inspect branch history and review diffs with staging and conflict resolution inside the workspace.
• Team collaboration: Use channels, direct messages, calls and jointly edited prompt drafts, with an organisation timeline for agent activity and optional sync.

Atlas is free and open source under Apache 2.0. It supports macOS 13+ on Apple Silicon and Intel, plus Windows 10+ on x64. Linux builds are untested. Agents retain their own authentication and model choices, and you can use your existing subscriptions or API keys.

The local workspace doesn't require an Atlas account. Session capture works without a network connection; coding agent connectivity depends on the agent and model provider you choose. Sessions stay in the project locally unless you opt into organisation sync, and Atlas scrubs secrets before storing them. Semantic retrieval uses on-device embeddings. Project knowledge stays in plain Markdown alongside your code.
