A workspace to build, deploy and manage AI agents and workflows.
## Quickstart
### Cloud-hosted: [sim.ai](https://sim.ai)
### Self-hosted
```bash
git clone https://github.com/simstudioai/sim.git && cd sim
bun run setup
```
Open [http://localhost:3000](http://localhost:3000)
## 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, knowledge, and scheduled tasks all live in the same workspace.
Tables — a database, built in
|
Files — one store for your team and every agent
|
Knowledge — your agents' memory
|
Scheduled tasks — runs on your schedule
|
## Self-hosting
**Requirements:** [Bun](https://bun.sh/) and [Docker](https://www.docker.com/).
`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](http://localhost:3000).
Manage your install with `bun run sim`:
```bash
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](https://ollama.ai) and [vLLM](https://docs.vllm.ai/). See the [self-hosting docs](https://docs.sim.ai/self-hosting/docker) 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](https://sim.ai/selfhost/settings/chat-keys).
## Environment Variables
See the [environment variables reference](https://docs.sim.ai/self-hosting/environment-variables) for the full list, or [`apps/sim/.env.example`](apps/sim/.env.example) for defaults.
