* improvement(knowledge): align connected-sources rows and move source chip left of filter/sort - Drop the -mx-2 on the connectors list so rows respect the ChipModalBody gutter: the row hover no longer bleeds to the modal edges and row content lines up with the px-4 header. - Add a 'leading' slot to ResourceOptions (left of the filter/sort cluster) and render the knowledge connected-source chip there instead of the far-right 'aside', so it reads as part of the control row. 'aside' stays right-aligned for the table editor's run/stop control. * improvement(resource): render options aside left of filter/sort The options-bar aside has a single other consumer (the table editor's embedded run/stop control), so instead of adding a separate slot, render aside itself to the left of the filter/sort cluster. Drops the extra slot and keeps one canonical control position; the run/stop control moves left too, which is fine for a status widget. * fix(resource): keep options aside grouped with filter/sort without a search bar Group aside + the filter/sort cluster in one ml-auto right-aligned container instead of relying on the search's flex-1 to anchor them. Without this, an options bar with no search (the embedded mothership table editor) split aside to the far left and filter/sort to the far right via justify-between. * docs(resource): clarify aside groups with filter/sort regardless of search
The open-source AI workspace where teams build, deploy, and manage AI agents. Build conversationally, visually, or with code. Connect 1,000+ integrations and every major LLM to automate real work.
Build everything in Chat
Your AI command center. Describe what you want in plain language. Sim knows your entire workspace and takes action: building agents, running them, querying data, and more.
Create files and documents
Generate documents, reports, and presentations from a single prompt, grounded in your workspace data.
Ground agents in your knowledge
Upload documents to a knowledge base and let agents answer questions from your own content.
Structured data with Tables
A database, built in. Store, query, and wire structured data into agent runs.
Build visually with Workflows
Prefer a canvas? Design agents block by block in the visual builder, and let Sim generate blocks, wire variables, and fix errors from natural language.
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
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
bun run prepare # Set up pre-commit hooks
- 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
# 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"
- Run migrations:
cd packages/db && bun run db:migrate
- Start development servers:
bun run dev:full # Starts Next.js app and realtime socket server
Or run separately: bun run dev (Next.js) and cd apps/sim && bun run dev:sockets (realtime).
Chat API Keys
Chat is a Sim-managed service. To use Chat on a self-hosted instance:
- Go to https://sim.ai → Settings → Chat keys and generate a Chat 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.
