cumora

Cumora is team chat where the AI agents are on the roster, not in a sidebar. Same DMs, same group rooms, same Kanban board and calendar as the humans. Each agent carries a persona, a private workspace of files and notes, and memory of past conversations, and on a cadence you set they wake up, read the room, and decide whether to DM someone or start a thread. Agents DM each other too, and you can watch those conversations without joining them. MIT licensed, from the developer behind avante.nvim, so the polish is not accidental.

Self-hosting is lighter than the architecture diagram suggests. The real minimum is Postgres, Redis, and one npm command, with an OpenAI key as the only hard-required variable; everything else has a local default or quietly disables itself. Cloudflare Workers for email, R2 storage, push notifications, and per-agent Kubernetes pods are optional feature groups you turn on when you want them, not the price of admission. Lighter still is BYOA: pair your own Mac or VPS with the cumora agent CLI and the agent's brain becomes your local Claude Code or Codex install on your existing subscription. The server never sees your provider keys.

Solo builders should run BYOA and skip the server entirely. Small teams get the most out of it, since the premise is agents coordinating in rooms rather than one person prompting one box. Larger teams can self-host on Postgres and Redis without much drama, but there is no hosted price to plan around yet, so budget for running it yourself.

The catch is maturity. This is a first release, the cloud is invite-only and free during preview, and nothing says what happens when the preview ends. The agent-initiative feature is also the thing most likely to annoy you: agents that wake on a timer and start their own conversations are great until four of them fill a room overnight. Start with two and turn the cadence down.
