* fix(wand): stop markdown code fences landing in generated code Strip fences from wand output for raw-value generation types, reset the conversation history when a Function block switches language, and give the Python prompt the worked example the JavaScript one already had. * fix(wand): preserve nested fences and retire stale history on reset Slice only the outermost fence delimiters so a fenced body containing line-leading backticks keeps every interior line, and skip the history append when a language reset retired the request mid-flight. * refactor(wand): drop unreachable guard in fence stripper The trimStart check made the -1 branch dead and stated "opens with a fence" twice. Derive it once from the first fence line's position. * chore(wand): remove unused onGenerationComplete callback No call site ever passed it, so the branch never ran. The props interface makes the removal compile-time verified. * fix(wand): never treat an interior fence line as the closer A truncated response whose body embeds line-leading backticks lost every line after the first embedded delimiter. Only the opening line and a final fence line are removed now. Sync the history epoch in a layout effect so a request settling before the passive flush cannot append to already-reset history. * test(wand): record the trailing-fence ambiguity as a decision A bare fence on the last line closes the wrapper in every well-formed response and is content only when generation stopped exactly on an embedded delimiter. Nothing separates the two, so assert the chosen behavior instead of leaving it implicit.
A workspace to build, deploy and manage AI agents and workflows.
Quickstart
Cloud-hosted: sim.ai
Self-hosted
git clone https://github.com/simstudioai/sim.git && cd sim
bun install
bun run setup
Capabilities
- Connect 1,000+ integrations and every major LLM
- Add Slack, Notion, HubSpot, Salesforce, databases, and more
- Build agents visually, conversationally, or with code
- Ingest files, knowledge bases, and structured table data
- Monitor runs, logs, schedules, and workflow activity
One workspace, every surface
Chat and workflows are just the start — tables, files, and knowledge all live in the same workspace.
Tables — a database, built in |
Files — one store for your team and every agent |
Knowledge — your agents' memory |
Self-hosting
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 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.
Chat API Keys
Chat is a Sim-managed service. bun run setup connects a Chat API key for you — sign in when it opens your browser and the key is stored automatically. To view, create, or revoke keys later, go to sim.ai/selfhost/settings/chat-keys.
Environment Variables
See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
