Choose agentmash if

Engineering teams where several developers run AI coding agents on the same repository at once.

  • Pricing counts developers only, with unlimited agents
  • Free for two developers, and Team's first month is free
  • Server does not see code unless a room enables diffs

Look elsewhere if: Solo developers or teams that just need a single coding agent (Cursor) without cross-machine coordination.

  • Free plan for two members and two cloud accounts
  • Read-only Cloudflare access with no full-access option offered
  • MCP and API reads are unlimited on every plan

Look elsewhere if: Teams that need a mature, full observability suite with predictable usage pricing (Datadog, Sentry).
