* improvement(scheduled-tasks): move recurrence into modal body as a section Replace the footer RecurrenceControl (a row of chip dropdowns) with a RecurrenceSection rendered between the prompt body and footer: a "Recurring" Switch toggles one-time vs repeat, and — once on — frequency and end (never, on a date, after N runs) are labeled ChipModalField rows aligned to the modal header/footer gutter. Toggling Recurring off now preserves the recurrence shape (cadence, end, and a passed-through custom cron) and only sets frequency: 'once', so toggling back on restores a conversationally-authored custom schedule instead of silently rewriting it to daily. Also restore the prompt editor's native scale (text-[15px], -0.015em tracking) so the editor reads the same in the chat input and the task modal body. * fix(scheduled-tasks): clear custom cron when switching frequency away from custom The Recurring toggle restores `frequency: 'custom'` when `recurrence.cron` is truthy, but switching the frequency dropdown away from custom kept the stale cron on the object — so editing a custom-cron task to Daily, then toggling Recurring off and back on, snapped it back to Custom and persisted the old cron. Clear `cron` in the non-custom frequency branches so it is present only while the cadence is genuinely custom (matching the type's "custom only" invariant), making the toggle's restore signal accurate. Also document the unreachable `once` branch in frequencyOptionFor as a type-exhaustiveness fallback (keeps the return type without a cast). * fix(scheduled-tasks): restore the prior cadence when re-enabling recurrence Toggling Recurring off collapsed frequency to 'once' but toggling back on forced 'daily' and cleared weekdays, so pausing a weekly/weekdays/monthly task and re-enabling it silently reset it to daily. Cache the last recurring cadence in a ref (written during render) and reinstate it on toggle-on, so a paused "Weekly on Mon" returns as weekly. This also subsumes the custom-cron restore — the ref remembers 'custom' across the one-time interval — so the toggle no longer special-cases cron. * improvement(scheduled-tasks): compose canonical modal separator, tidy imports Replace the recurrence section's hand-rolled `h-px bg-[var(--border)]` divider with the canonical ChipModalSeparator (now exported from the chip-modal barrel) so the modal's hairline has a single source of truth. Also unify loading.tsx icon imports onto the @/components/emcn barrel. --------- Co-authored-by: waleed <walif6@gmail.com>
The open-source AI workspace where teams build, deploy, and manage AI agents. Build conversationally, visually, or with code. Connect 1,000+ integrations and every major LLM to automate real work.
Build everything in Chat
Your AI command center. Describe what you want in plain language. Sim knows your entire workspace and takes action: building agents, running them, querying data, and more.
Create files and documents
Generate documents, reports, and presentations from a single prompt, grounded in your workspace data.
Ground agents in your knowledge
Upload documents to a knowledge base and let agents answer questions from your own content.
Structured data with Tables
A database, built in. Store, query, and wire structured data into agent runs.
Build visually with Workflows
Prefer a canvas? Design agents block by block in the visual builder, and let Sim generate blocks, wire variables, and fix errors from natural language.
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
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
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.
