* feat(fathom): add list meeting types tool and missing list-meetings filters - Add fathom_list_meeting_types tool (GET /meeting_types) - Add missing list-meetings params: includeHighlights, meetingType, calendarInviteesDomains, calendarInviteesDomainsType - Add missing meeting response fields: meeting_type, meeting_url, shared_with, highlights - Wire new operation and filters into the Fathom block * fix(fathom): expose meeting_url/highlights in outputs, stop force-sending domain type default - Add meeting_url and highlights to list_meetings outputs schema so they're addressable from downstream blocks (Greptile P1) - Drop the forced 'all' default on calendarInviteesDomainsType so the filter is only sent when a user explicitly picks a value (Greptile P2) * fix(fathom): never send calendar_invitees_domains_type=all to the API Match the existing Fathom connector's guard (meetingType !== 'all') so the request omits the param entirely when the value is the API's own default, regardless of what the dropdown shows selected in the UI. * fix(fathom): fully expose list_meetings meeting fields in outputs schema transformResponse already returned meeting_title, scheduled/recording times, recorded_by, calendar_invitees, default_summary, transcript, action_items, and crm_matches, but outputs.meetings.items.properties only documented a curated subset, leaving these fields unaddressable from downstream workflow blocks. Complete the schema to match the full Meeting object Fathom's API returns. * fix(fathom): mark recording_id optional in list_meetings outputs transformResponse maps recording_id as meeting.recording_id ?? null and the response type already types it number | null; the outputs schema now reflects that nullability. * fix(fathom): mark calendar_invitees email optional in list_meetings outputs Fathom's docs mark Invitee.email as nullable; the outputs schema now reflects that instead of declaring it as always-present.
A workspace to build, deploy and manage AI agents and workflows.
Quickstart
Cloud-hosted: sim.ai
Self-hosted
npx simstudio
Docker must be installed and running. Use -p, --port <port> to run Sim on a different port, or --no-pull to skip pulling the latest Docker images.
Capabilities
- Connect 1,000+ integrations and every major LLM
- Add Slack, Notion, HubSpot, Salesforce, databases, and more
- Build agents visually, conversationally, or with code
- Ingest files, knowledge bases, and structured table data
- Monitor runs, logs, schedules, and workflow activity
One workspace, every surface
Chat and workflows are just the start — tables, files, knowledge, and scheduled tasks all live in the same workspace.
Tables — a database, built in |
Files — one store for your team and every agent |
Knowledge — your agents' memory |
Scheduled tasks — runs on your schedule |
Self-hosting
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.
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).
Chat API Keys
Chat is a Sim-managed service. To use Chat on a self-hosted instance:
- Go to https://sim.ai → Settings → Chat keys and generate a Chat 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.
