* feat(account): let users delete their own account Adds a GDPR self-serve account deletion path: a preflight that reports what deletion would remove and every reason it would be refused, and a confirmed delete that erases the account and everything only it can reach. Deletion refuses while the account is still entangled rather than reassigning its content. Most tables reference user.id with ON DELETE CASCADE, and those cascades do not distinguish content in the account's own workspace from content it created inside somebody else's, so each blocker names the existing action that untangles it (leave the workspace, leave the organization, cancel the plan) — all of which already hand work over on their own tested paths. * fix(account): make deletion atomic and re-check privacy at delete time Reorders the teardown so nothing irreversible happens before the deletion is certain: anchors are handed over first (the fallible step, while everything is still recoverable), the workspace and user deletes now share one transaction, and the object-storage purge runs only after that commits. The workspace delete also re-checks inside the transaction that each workspace is still private, so a membership granted between the preview and the delete aborts the whole thing instead of destroying the new member's access. * fix(account): close deletion gaps found in review - Run the whole teardown in one transaction. The billing and ownership handovers now take the caller's transaction, so a refused deletion can no longer leave a workspace reassigned for a deletion that never happened. - Fail closed on a subscription read error. getHighestPriorityPersonalSubscription defaulted to returning null, which read as "no plan" and would have erased an account Stripe was still billing. - Erase the account's profile picture. It is personal data under our own storage prefix; an external provider avatar is left alone. - Enforce the storage purge cap while collecting keys rather than after, so an oversized account cannot exhaust memory before the cap applies.
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 update # pull/rebuild and apply Compose images
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.
