* feat(rootly): expand Rootly integration from 14 to 27 tools Add 13 new tools: delete_incident, get_alert, update_alert, acknowledge_alert, resolve_alert, create_action_item, list_action_items, list_users, list_on_calls, list_schedules, list_escalation_policies, list_causes, list_playbooks. Includes tool files, types, registry, block definition with subBlocks/conditions/params, and docs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(rootly): handle 204 No Content response for delete_incident DELETE /v1/incidents/{id} returns 204 with empty body. Avoid calling response.json() on success — return success/message instead. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(rootly): remove non-TSDoc comments, add empty body to acknowledge_alert Remove all inline section comments from block definition per CLAUDE.md guidelines. Add explicit empty JSON:API body to acknowledge_alert POST to prevent potential 400 from servers expecting a body with Content-Type. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(rootly): send empty body on resolve_alert, guard assignedToUserId parse resolve_alert now sends { data: {} } instead of undefined when no optional params are provided, matching the acknowledge_alert fix. create_action_item now validates assignedToUserId is numeric before parseInt to avoid silent NaN coercion. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(rootly): extract on-call relationships from JSON:API relationships/included On-call user, schedule, and escalation policy are exposed as JSON:API relationships, not flat attributes. Now extracts IDs from item.relationships and looks up names from the included array. Adds ?include=user,schedule,escalation_policy to the request URL.

The open-source platform to build AI agents and run your agentic workforce. Connect 1,000+ integrations and LLMs to orchestrate agentic workflows.
Build Workflows with Ease
Design agent workflows visually on a canvas—connect agents, tools, and blocks, then run them instantly.
Supercharge with Copilot
Leverage Copilot to generate nodes, fix errors, and iterate on flows directly from natural language.
Integrate Vector Databases
Upload documents to a vector store and let agents answer questions grounded in your specific content.
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
Background worker note
The Docker Compose stack starts a dedicated worker container by default. If REDIS_URL is not configured, the worker will start, log that it is idle, and do no queue processing. This is expected. Queue-backed API, webhook, and schedule execution requires Redis; installs without Redis continue to use the inline execution path.
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
- 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
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 && bunx drizzle-kit migrate --config=./drizzle.config.ts
- Start development servers:
bun run dev:full # Starts Next.js app, realtime socket server, and the BullMQ worker
If REDIS_URL is not configured, the worker will remain idle and execution continues inline.
Or run separately: bun run dev (Next.js), cd apps/sim && bun run dev:sockets (realtime), and cd apps/sim && bun run worker (BullMQ worker).
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.
