Multica
Multica is a workspace where issues are assigned to AI coding agents, which run through locally installed agent CLIs such as Claude Code, Codex, Cursor and Copilot (26 listed). A daemon on your own machine executes the work next to your code and reports progress back to the issue, which ends in review rather than main. The backend is Go with PostgreSQL 17, and clients cover web, Electron desktop and an Expo mobile app.
Who it is for: Teams coordinating several coding agents on their own machines and Git host
Strengths
- Drives 26 existing agent CLIs, so no model or API lock-in
- Execution log replays every tool call, command and error per run
- Daemon runs on your own machine, so code stays there
- Self-host via Docker Compose or Helm; works with GitHub, GitLab, Gitea, Forgejo
Weaknesses
- Does not ship agents; each runtime needs a CLI installed and signed in
- Custom Multica License (Apache 2.0 plus conditions on hosting, embedding, branding)
- Requires Docker, a Go backend and PostgreSQL 17 to self-host
- iOS app builds from source only; DingTalk, WeCom, Telegram are community-maintained
- no GPU
- Docker + Compose
- Needs PostgreSQL 17, Docker, agent CLI (Claude Code, Codex, etc.)
- Models: Claude Code, OpenAI Codex, Cursor Agent, GitHub Copilot CLI, OpenCode
Sim
Sim is a Next.js and Bun app on PostgreSQL that builds agents visually, by chat or in code, with monitoring, schedules and logs. The npx sim-setup wizard (Node.js 20+ and Docker) provisions the database, secrets and images and serves port 3000. Tables, files and knowledge bases share the workspace, 1,000+ integrations such as Slack, Notion and HubSpot are available, and local models run via Ollama or vLLM.
Who it is for: Teams wanting a hosted-style agent builder on their own servers
Strengths
- Built-in tables, file store and knowledge bases alongside workflows and chat
- 1,000+ integrations including Slack, Notion, HubSpot, Salesforce and databases
- Local models via Ollama and vLLM; Apache-2.0 license
- sim-setup wizard adds email, storage, sandbox, jobs, cache or knowledge later
Weaknesses
- Chat is a Sim-managed service; self-hosted installs need a Chat API key from sim.ai
- Setup prompt in the README notes the Compose stack needs 12 GB+ RAM
- Background jobs use Trigger.dev and remote code execution uses E2B
- Self-hosting goes through an npx wizard rather than a documented compose file
- RAM ≥ 12 GB
- no GPU
- Docker + Compose
- Needs PostgreSQL, Docker, Sim Chat API key
- Models: Ollama, vLLM
- port 3000
