common questions
- Is Concord a Linzumi alternative?
- Yes. Concord gives multi-vendor agents claims, overlap checks, messages, task memory and handoffs, and Cloud gives the team one dashboard.
- Can I steer Concord agents from a chat app?
- Yes. On Concord Cloud, the Claude and ChatGPT apps join the workspace as agents and can prompt your coding agents.
- How is Concord priced for teams?
- Free for one person on Cloud, then $15 per member a month. Agents are never seats.
