* Add queueing for hosted keys * feat(rate-limiter): FIFO queue for hosted-key per-workspace fairness Replace the per-call distributed lock with a Redis-backed FIFO queue so callers within a workspace get strict ordering instead of racing the bucket. Adds heartbeat-based crash recovery and dead-head reaping in a single Lua script. Bumps Exa search hosted RPM from 5 to 60. * fix(rate-limiter): bound hosted-key queue wait to execution budget; fix heartbeat + telemetry Tie the per-workspace hosted-key queue wait to the surrounding execution budget instead of a flat 5-minute cap. acquireKey now accepts the execution AbortSignal (threaded from ExecutionContext): when present, the wait is bounded by the run's actual plan timeout / cancellation, with the enterprise async ceiling as a backstop; when absent it falls back to MAX_QUEUE_WAIT_MS. This lets long-running async (Trigger.dev) runs use their full budget while no longer letting a single queued call burn a short sync run's entire budget. Also addresses Greptile review: - P1: share one lastHeartbeatAt across all wait phases and cap every sleep to HEARTBEAT_REFRESH_INTERVAL_MS so a long low-RPM retryAfterMs can no longer let the head's heartbeat lapse mid-wait and break FIFO ordering. - P2: derive hostedKeyQueueWaited telemetry reason from the actual bottleneck (queue_position / dimension / actor_requests) instead of hardcoding it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(rate-limiter): make hosted-key queue waits abort-interruptible Replace the plain capped sleeps in the queue-head and bucket-capacity wait loops with an interruptibleSleep that resolves early when the execution AbortSignal fires (timeout or cancellation), cleaning up its own timer and listener. Previously a cancelled/timed-out run could overshoot by up to the heartbeat cap (~10s) before the loop re-checked its budget; now it wakes within a tick. The cap remains for heartbeat renewal.

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.
