* fix(mothership): reconcile stuck conversation_id against Redis lock to clear stuck-yellow task tiles

copilot_chats.conversation_id has no TTL/heartbeat, so when a stream
process dies before the clear path runs (pod OOM, SIGKILL, uncaught
throw, deploy mid-stream) the column is orphaned and the task tile
renders yellow forever. The Redis lock at copilot:chat-stream-lock:<chatId>
is the canonical liveness signal and self-heals via 60s TTL + 20s
heartbeat, but the mothership APIs weren't consulting it.

Adds read-time reconciliation: a batched MGET helper checks whether
each persisted conversation_id still has a live Redis lock, and both
GET /api/mothership/chats and GET /api/mothership/chats/[chatId]
rewrite the marker to null when the lock has expired. No DB writes;
stuck rows self-heal on next fetch.

* test(mothership): clarify test name to reflect that getActiveChatStreamIds is called with empty candidateIds

* address comments

* fix state machine issue

* cleanup code and fix types

Quickstart

Cloud-hosted: sim.ai

Sim.ai

Self-hosted: NPM Package

npx simstudio

→ http://localhost:3000

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

Open http://localhost:3000

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

  1. Clone and install:
git clone https://github.com/simstudioai/sim.git
cd sim
bun install
bun run prepare  # Set up pre-commit hooks
  1. 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.

  1. 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"
  1. Run migrations:
cd packages/db && bun run db:migrate
  1. 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_KEY environment 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.
