* perf(search): cap Cmd-K result groups so typing isn't blocked by reshuffle Every result group re-rendered its full match set on each keystroke — the catalog alone is 1,000+ tool operations, plus all workflows/files in large workspaces — so the deferred re-render that reshuffles results stalls the input and drops the next character. Add a per-group cap (filterAndCap, MAX_RESULTS_PER_GROUP=50) applied to every variable-size group. Results are already score-sorted, so the cap only trims the low-relevance tail while keeping the DOM and per-keystroke reconciliation bounded. No UX changes. * perf(search): scope the result cap to active queries, never the browse list Keep the empty state byte-for-byte identical to before — capping applies only to the top-ranked matches of an active query (the reshuffling per-keystroke render that stalls input), never to the full browsable list. No browsable result a user could otherwise see is hidden. * fix(search): rank blocks/tools by name so exact name matches win Blocks and tools were ranked against their full searchValue (name + type + every command-searchable option label), so an exact name match couldn't earn the exact-match bonus and paid a length penalty inflated by option text — e.g. "Agent" lost to "Pi Coding Agent" for the query "agent". Rank by name first via a new optional secondary accessor on filterAndSort/filterAndCap, falling back to searchValue only when the name doesn't match, so an exact name match always wins while a block stays findable by an option label. * fix(search): treat whitespace-only queries as browse A whitespace-only query (e.g. a single space) was truthy, so it both filtered (a space matches the spaces in multi-word labels) and capped large groups to 50 while the palette looked empty. Trim the query at the source in filterAndSort so every caller treats whitespace-only as browse, and decide the cap on the trimmed query — whitespace-only input now returns the full, unfiltered browse state. * fix(search): keep integrations catalog hidden on whitespace-only input The filteredIntegrations guard used the raw deferredSearch, so a whitespace-only value passed it while filterAndCap trimmed the same value to browse and returned the full catalog. Guard on deferredSearch.trim() to match the trimmed-emptiness semantics — the catalog stays hidden until the user types something meaningful.
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.
