Sim

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

→ http://localhost:3000

#### Note Docker must be installed and running on your machine.

#### Options

Self-hosted: Docker Compose

git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d

Open http://localhost:3000

#### 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

1. 1.Clone and install:

git clone https://github.com/simstudioai/sim.git
cd sim
bun install
bun run prepare  # Set up pre-commit hooks

1. 1.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.

1. 1.Configure environment:

cp apps/sim/.env.example apps/sim/.env
# Create your secrets
perl -i -pe "s/your_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_internal_api_secret/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_api_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
# DB configs for migration
cp packages/db/.env.example packages/db/.env
# Edit both .env files to set DATABASE_URL="postgresql://postgres:your_password@localhost:5432/simstudio"

1. 1.Run migrations:

cd packages/db && bun run db:migrate

1. 1.Start development servers:
