* improvement(tables): improve table filtering UX - Replace popover filter with persistent inline panel below toolbar - Add AND/OR toggle between filter rules (shown in Where label slot) - Sync filter panel state from applied filter on open - Show filter button active state when filter is applied or panel is open - Use readable operator labels matching dropdown options - Add Clear filters button (shown only when filter is active) - Close filter panel when last rule is removed via X - Fix empty gap rows appearing in filtered results by skipping position gap rendering when filter is active - Add toggle mode to ResourceOptionsBar for inline panel pattern - Memoize FilterRuleRow for perf, fix filterTags key collision, remove dead filterActiveCount prop * fix(table-filter): use ref to stabilize handleRemove/handleApply callbacks Reading rules via ref instead of closure eliminates rules from useCallback dependency arrays, keeping callbacks stable across rule edits and preserving the memo() benefit on FilterRuleRow. * improvement(tables,kb): remove hacky patterns, fix KB filter popover width - Remove non-TSDoc comment from table-filter (rulesRef pattern is self-evident) - Simplify SearchSection: remove setState-during-render anti-pattern; controlled input binds directly to search.value/onChange (simpler and correct) - Reduce KB filter popover from w-[320px] to w-[200px]; tag filter uses vertical layout so narrow width works; Status-only case is now appropriately compact * feat(knowledge): add sort and filter to KB list page Sort dropdown: name, documents, tokens, created, last updated — pre-sorted externally before passing rows to Resource. Active sort highlights the Sort button; clear resets to default (created desc). Filter popover: filter by connector status (All / With connectors / Without connectors). Active filter shown as a removable tag in the toolbar. * feat(files): add sort and filter to files list page * feat(scheduled-tasks): add sort and filter to scheduled tasks page * fix(table-filter): use explicit close handler instead of toggle * improvement(files,knowledge): replace manual debounce with useDebounce hook and use type guards for file filtering * fix(resource): prevent popover from inheriting anchor min-width * feat(tables): add sort to tables list page * feat(knowledge): add content and owner filters to KB list * feat(scheduled-tasks): add status and health filters * feat(files): add size and uploaded-by filters to files list * feat(tables): add row count, owner, and column type filters * improvement(scheduled-tasks): use combobox filter panel matching logs UI style * improvement(knowledge): use combobox filter panel matching logs UI style * improvement(files): use combobox filter panel matching logs UI style Replaces button-list filters with Combobox-based multi-select sections for file type, size, and uploaded-by filters, aligning the panel with the logs page filter UI. * improvement(tables): use combobox filter panel matching logs UI style * feat(settings): add sort to recently deleted page Add a sort dropdown next to the search bar allowing users to sort by deletion date (default, newest first), name (A–Z), or type (A–Z). * feat(logs): add sort to logs page * improvement(knowledge): upgrade document list filter to combobox style * fix(resources): fix missing imports, memoization, and stale refs across resource pages * improvement(tables): remove column type filter * fix(resources): fix filter/sort correctness issues from audit * fix(chunks): add server-side sort to document chunks API Chunk sort was previously done client-side on a single page of server-paginated data, which only reordered the current page. Now sort params (sortBy, sortOrder) flow through the full stack: types → service → API route → query hook → useDocumentChunks → document.tsx. * perf(resources): memoize filterContent JSX across all resource pages Resource is wrapped in React.memo, so an unstable filterContent reference on every parent re-render defeats the memo. Wrap filterContent in useMemo with correct deps in all 6 pages (files, tables, scheduled-tasks, knowledge, base, document). * fix(resources): add missing sort options for all visible columns Every column visible in a resource table should be sortable. Three pages had visible columns with no sort support: - files.tsx: add 'owner' sort (member name lookup) - scheduled-tasks.tsx: add 'schedule' sort (localeCompare on description) - knowledge.tsx: add 'connectors' (count) and 'owner' (member name) sorts Also add 'members' to processedKBs deps in knowledge.tsx since owner sort now reads member names inside the memo. * whitelabeling updates, sidebar fixes, files bug * increased type safety * pr fixes

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.
