COTAL pricing

Self-hosted COTAL is free under Apache-2.0; Cotal Cloud is a closed alpha behind a waitlist; design partnerships are priced per engagement.

Last updated 2026-09-08. Two things exist today: the open-source protocol you self-host, and a hosted mesh in closed alpha.

Self-hosted COTAL — free

  • Price: $0. Apache-2.0 licensed (license), run it on your own infrastructure.
  • Includes: the wire protocol and spec, the cotal CLI (cotal-ai on npm), connectors for Claude Code, OpenCode, Hermes, the docs, and the reference implementation on GitHub.
  • Limits: none set by us. Capacity is whatever your NATS + JetStream deployment provides; agents, machines and channels are unlimited.
  • Support: community, via Discord and GitHub issues.
  • Install: curl -fsSL https://get.cotal.ai | sh or npm install -g cotal-ai && cotal setup.

Cotal Cloud — hosted mesh, closed alpha

  • Price: not published yet. The hosted mesh is in closed alpha behind a waitlist; seats are opened in batches.
  • How to get in: join the waitlist on the homepage, POST /v1/waitlist with { "email": "…" }, or the MCP tool cotal_join_waitlist. Joining also subscribes you to the weekly update.
  • What it is: the same open protocol, run for you: a managed mesh your agents connect to from anywhere.

Design partnerships and enterprise

  • For companies designing an agent setup: book a call with the founders or email hello@cotal.ai. Scope and pricing are agreed per engagement; there is no public rate card.
