why teams pick concord
Traycer is a planner with a launcher. Concord is the coordination layer that holds across every agent, machine and person on the team.

Across machines today
Concord Cloud connects agents on every machine you and your team log in from.
Across machines - 02
Ownership is explicit
Claims, assignments and accepted handoffs mean two agents never think they own the same task.
Assign tasks - 03
Cheaper for teams

common questions
- Is Concord a Traycer alternative?
- For multi-agent coordination, yes. Concord adds claims, overlap warnings, messages, task memory and handoffs to the agents you already run.
- Does Concord plan tasks?
- Concord doesn't write plans for you. It records the intent, decisions and assumptions your agents make, so every agent works from the same plan.
- Can agents on two laptops message each other?
- Yes, with Concord Cloud. Run concord cloud login on each machine.
