* feat(profound): add Profound AI visibility and analytics integration * fix(profound): fix import ordering and JSON formatting for CI lint * fix(profound): gate metrics mapping on current operation to prevent stale overrides * fix(profound): guard JSON.parse on filters, fix offset=0 falsy check, remove duplicate prompt_answers in FILTER_OPS * lint * fix(docs): fix import ordering and trailing newline for docs lint * fix(scripts): sort generated imports to match Biome's organizeImports order * fix(profound): use != null checks for limit param across all tools * fix(profound): flatten block output type to 'json' to pass block validation test * fix(profound): remove invalid 'required' field from block inputs (not part of ParamConfig) * fix(profound): rename tool files from kebab-case to snake_case for docs generator compatibility * lint * fix(docs): let biome auto-fix import order, revert custom sort in generator * fix(landing): fix import order in sim icon-mapping via biome * fix(scripts): match Biome's exact import sort order in docs generator * fix(generate-docs): produce Biome-compatible JSON output The generator wrote multi-line arrays for short string arrays (like tags) and omitted trailing newlines, causing Biome format check failures in CI. Post-process integrations.json to collapse short arrays onto single lines and add trailing newlines to both integrations.json and meta.json.

The open-source platform to build AI agents and run your agentic workforce. Connect 1,000+ integrations and LLMs to orchestrate agentic workflows.
Build Workflows with Ease
Design agent workflows visually on a canvas—connect agents, tools, and blocks, then run them instantly.
Supercharge with Copilot
Leverage Copilot to generate nodes, fix errors, and iterate on flows directly from natural language.
Integrate Vector Databases
Upload documents to a vector store and let agents answer questions grounded in your specific content.
Quickstart
Cloud-hosted: sim.ai
Self-hosted: NPM Package
npx simstudio
Note
Docker must be installed and running on your machine.
Options
| Flag | Description |
|---|---|
-p, --port <port> |
Port to run Sim on (default 3000) |
--no-pull |
Skip pulling latest Docker images |
Self-hosted: Docker Compose
git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d
Background worker note
The Docker Compose stack starts a dedicated worker container by default. If REDIS_URL is not configured, the worker will start, log that it is idle, and do no queue processing. This is expected. Queue-backed API, webhook, and schedule execution requires Redis; installs without Redis continue to use the inline execution path.
Sim also supports local models via Ollama and vLLM — see the Docker self-hosting docs for setup details.
Self-hosted: Manual Setup
Requirements: Bun, Node.js v20+, PostgreSQL 12+ with pgvector
- Clone and install:
git clone https://github.com/simstudioai/sim.git
cd sim
bun install
- Set up PostgreSQL with pgvector:
docker run --name simstudio-db -e POSTGRES_PASSWORD=your_password -e POSTGRES_DB=simstudio -p 5432:5432 -d pgvector/pgvector:pg17
Or install manually via the pgvector guide.
- Configure environment:
cp apps/sim/.env.example apps/sim/.env
cp packages/db/.env.example packages/db/.env
# Edit both .env files to set DATABASE_URL="postgresql://postgres:your_password@localhost:5432/simstudio"
- Run migrations:
cd packages/db && bunx drizzle-kit migrate --config=./drizzle.config.ts
- Start development servers:
bun run dev:full # Starts Next.js app, realtime socket server, and the BullMQ worker
If REDIS_URL is not configured, the worker will remain idle and execution continues inline.
Or run separately: bun run dev (Next.js), cd apps/sim && bun run dev:sockets (realtime), and cd apps/sim && bun run worker (BullMQ worker).
Copilot API Keys
Copilot is a Sim-managed service. To use Copilot on a self-hosted instance:
- Go to https://sim.ai → Settings → Copilot and generate a Copilot API key
- Set
COPILOT_API_KEYenvironment variable in your self-hosted apps/sim/.env file to that value
Environment Variables
See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
