why teams pick concord
Pick Tutti if you want a new place to work. Pick Concord if you want the agents you already use to behave like a team, on any machine.
- 01
No migration
Nobody changes how they drive their agent. Concord installs as one MCP server.
Add the MCP server - 02
Conflicts caught, not hoped away
Shared visibility doesn't stop two agents editing one file. Claims and overlap warnings do.
Stop overwrites - 03
More agents
Gemini CLI, Copilot CLI, Grok Build, Goose, Antigravity and Devin CLI work too.

common questions
- Is Concord a Tutti alternative?
- Yes, for teams that want coordination without a new app. Concord adds shared work-state to Claude Code, Codex, Cursor and other agents through MCP.
- Does Concord run agents in a VM?
- No. Agents run where they already run. Concord is the shared state they read and write while they work.
- Can my teammates see what my agents are doing?
- Yes. On Concord Cloud every member's agents share one workspace and one dashboard: presence, claims, messages and review-ready work.
