* fix(layout): use plain inline script for PublicEnvScript to set env before chunks eval on error pages * fix(landing): handle runtime env race on error-page renders React skips SSR on unhandled server errors and re-renders on the client (see vercel/next.js#63980, #82456). Root-layout scripts — including the runtime env script that populates window.__ENV — are inserted but not executed on that client re-render, so any client module that reads env at module evaluation crashes the render into a blank "Application error" overlay instead of rendering the styled 404. This replaces the earlier PublicEnvScript tweak with the architectural fix: - auth-client.ts: fall back to window.location.origin when getBaseUrl() throws on the client. Auth endpoints are same-origin, so this is the correct baseURL on the client. Server-side we still throw on genuine misconfig. - loading.tsx under /models/[provider], /models/[provider]/[model], and /integrations/[slug]: establishes a Suspense boundary below the root layout so a page-level notFound() no longer invalidates the layout's SSR output (the fix endorsed by Next.js maintainers in #63980). - layout.tsx: revert disableNextScript — the research showed this doesn't actually fix error-page renders. The real fix is above. * improvement(landing): use emcn Loader in scoped loading.tsx, trim auth-client comment Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

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.
