Multica

vlatest

Open-source orchestration for AI agent teams -- assign issues, track progress kanban-style, compound skills

Install

What's included

  • Multica server -- backend, web UI, and PostgreSQL from official GHCR images
  • Works with Claude Code, Codex, OpenCode, OpenClaw, Hermes, and more
  • Caddy -- reverse proxy with auto-HTTPS
  • Measured footprint -- the whole stack idles around 100 MB of RAM

After install

  • Create your account in the web UI (verification codes print to backend logs until an email provider is configured)
  • Install the multica CLI on the machines where your agents run
  • Connect them to your server: multica setup self-host

Changelog

v1.0.22026-07-13
  • /ws and /api/* now route to the backend through Caddy per the upstream self-host guide -- remote agent daemons could never connect before
  • .env (JWT signing key, database password) no longer world-readable
  • Connect instructions now pass --server-url/--app-url (the bare command pointed at localhost on the agent machine)
  • Webhook rate limiting sees real client IPs (MULTICA_TRUSTED_PROXIES)
v1.0.12026-07-13
  • Default host now uses the public IP / verified rDNS -- the public URL and FRONTEND_ORIGIN now match how users actually reach the server
  • Local smoke-test support via the VIRTUA_BASE_URL override
v1.0.02026-07-12
  • Initial release -- self-host stack via official images with public origin configured
