* improvement(forking): make webhook url mapping clear * fix(forking): honour drops before the unmapped gate, match provider on URL adoption Review round 1 on #6272. - Drop was inert for required references: `postCopyUnmappedRequired` gates before the cleared-ref gate that honours acknowledgments, so a source-deleted reference on a required field still failed with "map all required ... first". Verified drops are now resolved once (`verifyForkDropAcknowledgments`) and subtracted from both gates. Verification is not optional: an unmapped reference of a non-blocking kind (credential, env-var) never re-blocks downstream, so subtracting raw acknowledgments would let a crafted payload skip the required gate. - URL adoption now requires provider equality. A count-only 1:1 pairing could hand a GitHub URL to an arriving Slack trigger, keeping the endpoint alive while every request failed signature verification - and reporting the URL as preserved. - `resolveTriggerId` moved from `lib/webhooks/deploy.ts` to `@/triggers/webhook-url` so the deploy path and the fork's provider check share one resolution. - Trigger URL warnings render the full public URL in the heads-up section and name the URL in the overwrite confirm, where identical workflow names were ambiguous. - The Drop control renders once per resource and states how many fields it covers; the remapper clears by reference, so a per-row control implied a choice the write path cannot honour. - Export clears `workflow-selector`: nothing on the import path remaps workflow ids (`import-export.ts` re-creates each workflow under a fresh id), so a preserved reference dangled - bundle or not.

A workspace to build, deploy and manage AI agents and workflows.
Quickstart
Cloud-hosted: sim.ai
Self-hosted
git clone https://github.com/simstudioai/sim.git && cd sim
bun install
bun run setup
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, and knowledge all live in the same workspace.
Tables — a database, built in |
Files — one store for your team and every agent |
Knowledge — your agents' memory |
Self-hosting
bun run setup is an interactive wizard: it provisions the database, generates secrets, writes your .env files, connects a Chat API key, and starts Sim the way you choose:
- Local dev — run from source to contribute or hack on Sim
- Docker Compose — a self-contained instance for testing self-hosting
- Kubernetes (Helm) — deploy to a local cluster
When it finishes, open http://localhost:3000.
Reconfigure an optional capability without rerunning the full wizard:
bun run setup status
bun run setup email
bun run setup storage
bun run setup sandbox
bun run setup jobs
bun run setup cache
bun run setup knowledge
bun run setup llm
bun run setup integration slack
bun run setup status detects the effective local-dev, Docker Compose, or current-context
Helm configuration and reports configured, missing, or invalid capabilities and OAuth
integrations without printing credential values. This is separate from bun run sim status,
which reports whether installed services are running and healthy.
Manage your install with bun run sim:
bun run sim start | stop | restart # bring your install up / down / cycle
bun run sim status # what's installed and healthy
bun run sim logs # follow logs
bun run sim doctor # diagnose configuration problems
bun run sim down # remove containers (data kept)
bun run sim reset # archive .env and wipe managed data
sim detects how you're running (Docker Compose, local dev, or Kubernetes) and acts accordingly.
Prefer a bare sim? Run bun link once — but note sim lands in ~/.bun/bin, which Homebrew's bun doesn't add to your PATH, so you may need export PATH="$HOME/.bun/bin:$PATH" in your shell profile.
Sim also supports local models via Ollama and vLLM. See the self-hosting docs for details.
Chat API Keys
Chat is a Sim-managed service. bun run setup connects a Chat API key for you — sign in when it opens your browser and the key is stored automatically. To view, create, or revoke keys later, go to sim.ai/selfhost/settings/chat-keys.
Environment Variables
See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
