* docs(uploads): clarify QUOTA_EXEMPT_STORAGE_CONTEXTS logs entry in JSDoc * fix(date-picker): eliminate infinite re-render on re-open with existing selection The useEffect that syncs picker state on open had initialStart and initialEnd — Date objects computed on every render — in its dependency array. Because Object.is returns false for any two distinct Date instances, the effect fired on every render when open=true, calling setRangeStart/setRangeEnd and triggering another render, producing an infinite loop that crashed the page. Fix: compute start and end as local variables inside the effect and use the stable string props (props.startDate, props.endDate) as deps instead. Also removes the redundant typeof fileSize === 'number' guard in the multipart quota check — fileSize is z.number() (required) in the contract so it can never be undefined at that point. * refactor(date-picker): comprehensive cleanup and reliable crash fix The previous fix still had derived Date objects in useEffect deps. Object.is(new Date(), new Date()) === false, so any Date in deps causes the effect to run every render, reproducing the infinite loop on re-open with existing time selection. Key changes: - useEffect deps now use only stable primitives (startDate, endDate strings) and compute Date values inside the effect — eliminating the loop - Replace `rest as any` with a FlatDatePickerProps merged type for safe, typed destructuring across the discriminated union - Remove initialStart/initialEnd render-scope variables; compute inline or inside effects to keep derivation local to each use site - Callbacks use destructured props (onChange, onRangeChange, etc.) instead of props.x references - Remove verbose TSDoc on internal callbacks — names are self-documenting - Preserve all existing JSX structure and CalendarMonth logic unchanged

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).
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.
