Decision brief

Sim, a platform for orchestrating AI agents with TypeScript support and local model capabilities via frameworks like Next.js and React.

Good fit when

When you need to build low-code/no-code applications using TypeScript and want integration with popular web frameworks such as Next.js and React.
If your project requires the use of local models with Ollama or vLLM, allowing for more control over model deployment and execution.

Avoid when

For projects that do not require low-code/no-code capabilities or when TypeScript is not preferred as a development language.
Projects may avoid Sim if they have strict requirements for cloud-based models only, and the use of local models via Ollama or vLLM is unnecessary.

Self-hosting

Requirements: Bun and Docker.

bun run setup is an interactive wizard: it provisions the database, generates secrets, writes your .env files, connects a Chat API key, and starts Sim the way you choose:

Local dev — run from source to contribute or hack on Sim
Docker Compose — a self-contained instance for testing self-hosting
Kubernetes (Helm) — deploy to a local cluster

When it finishes, open http://localhost:3000.

Reconfigure an optional capability without rerunning the full wizard:

bun run setup status
bun run setup email
bun run setup storage
bun run setup sandbox
bun run setup jobs
bun run setup cache
bun run setup knowledge
bun run setup llm
bun run setup integration slack

bun run setup status detects the effective local-dev, Docker Compose, or current-context Helm configuration and reports configured, missing, or invalid capabilities and OAuth integrations without printing credential values. This is separate from bun run sim status, which reports whether installed services are running and healthy.

Manage your install with bun run sim:

bun run sim start | stop | restart   # bring your install up / down / cycle
bun run sim update                   # pull/rebuild and apply Compose images
bun run sim status                    # what's installed and healthy
bun run sim logs                      # follow logs
bun run sim doctor                    # diagnose configuration problems
bun run sim down                      # remove containers (data kept)
bun run sim reset                     # archive .env and wipe managed data

sim detects how you're running (Docker Compose, local dev, or Kubernetes) and acts accordingly.

Prefer a bare sim? Run bun link once — but note sim lands in ~/.bun/bin, which Homebrew's bun doesn't add to your PATH, so you may need export PATH="$HOME/.bun/bin:$PATH" in your shell profile.

Sim also supports local models via Ollama and vLLM. See the self-hosting docs for details.
