* fix(docker): use full bun.lock and copy it into builder
The staging build for app.Dockerfile (commit dc2022995, PR #4322) is
failing in two ways after switching to turbo prune:
1. turbo 2.9.6's pruned bun.lock is malformed for bun 1.3.x:
error: Failed to resolve prod dependency 'wrap-ansi' for package
'log-update' at bun.lock:2688:5
Bun ignores it and falls back to a fresh resolve (~7m install).
2. Next.js 16.1.6's Turbopack production build can't infer the workspace
root because /app/bun.lock doesn't exist in the builder stage:
Error: We couldn't find the Next.js package (next/package.json)
from the project directory: /app/apps/sim
This blocks the build entirely.
Fix:
- deps stage: use the full bun.lock from /app/bun.lock (the original
lockfile after `COPY . .` in pruner) instead of the broken
/app/out/bun.lock that turbo prune emits.
- builder stage: also copy the full bun.lock to /app/bun.lock so
Turbopack and turborepo can detect the workspace root.

* chore(ci): bump deprecated Node.js 20 actions to Node.js 24 versions
GitHub Actions runners emit deprecation warnings for actions still on the
Node.js 20 runtime. Node.js 20 will be force-upgraded by GitHub on
2026-06-02 and removed on 2026-09-16.
Bumps to the latest stable major versions, all of which use Node.js 24:
- actions/cache: v4 -> v5
- actions/setup-node: v4 -> v6
- aws-actions/configure-aws-credentials: v4 -> v6
- docker/login-action: v3 -> v4
All require GHA runner v2.327.1+ which Blacksmith already runs.

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.
