* fix(selectors): fetch all pages for paginated dropdown list routes Dropdown selectors fetched only the first page of paginated provider APIs, silently hiding results past page one. Add bounded server-side draining to the list routes across Microsoft Graph, Google, Notion, Atlassian, Linear, AWS CloudWatch, and offset/token REST APIs, plus a shared client-side drain cap in the selector hook. Response shapes, stored values, and tool execution are unchanged; CloudWatch list tools still honor a caller-supplied limit. Also fixes the Word file picker that was searching for .xlsx files. * fix(selectors): harden JSM and Monday pagination draining - JSM service-desk/request-type drains advance `start` by the actual row count returned (not the fixed page size) and stop on an empty page, so a short non-final page can't skip items. - Monday boards drain now checks `response.ok` per page, surfacing a mid-drain HTTP failure instead of treating it as an empty final page and returning a partial 200. * docs(selectors): clarify JSM drain advances start by actual row count The offset-advancement fix (advance `start` by the rows returned, not the fixed page size) landed in 7b19788a8; update the TSDoc to match so it no longer reads as advancing by `limit`. * fix(selectors): drain fetchPage in direct fetchList callers Making `fetchList` optional left three direct callers (outside the useSelectorOptions hook) calling it unguarded, which broke the build's type check. Route them through a shared `loadAllSelectorOptions` helper that uses `fetchList` when present and otherwise drains `fetchPage`. This also prevents a regression: `confluence.spaces` / `knowledge.documents` now paginate via `fetchPage` only, and these callers (search/replace, value resolution) would otherwise have silently returned no options. * chore(selectors): rename MAX_PAGE_PAGES to MAX_NOTION_PAGES for readability

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.
