* feat(self-host): align Docker Compose with Helm and overhaul self-hosting docs Docker Compose shipped no scheduler, so scheduled workflows, every polling trigger, connector syncs, the outbox, and data drains silently never ran. Adds a cron service running the same 18 jobs the Helm chart schedules as CronJobs, and closes the remaining behavioral gaps between the two paths: bundled Redis in the chart, no hosted plan caps in chart defaults, pinned image tags, and fail-fast secrets. A CI check keeps the schedulers in sync. Also rewrites the self-hosting docs: 14 new pages, 8 updated, reorganized into Install / Configure / Operate. * fix(self-host): drop bun install from chart CI, remove air-gapped and backup docs The scheduler-parity check pulled a full dependency install into the chart-validation job, which fails building isolated-vm on that runner. Rewritten to use only node builtins so the job installs nothing. Also removes the air-gapped and backup/restore pages, and stops pinning a concrete release in the docs so the examples do not go stale each release. * fix(helm): bundle Redis in secret-manager modes unless the URL is supplied Suppressing Redis whenever a secret mode was active left those deployments with no Redis at all — REDIS_URL is optional there and both shipped examples omit it. The chart now steps aside only on a detectable signal: an explicit app.env.REDIS_URL, an ESO remoteRefs.app.REDIS_URL mapping, or the new redis.provideUrl=false opt-out for a pre-created Secret it cannot read. * fix(compose): derive realtime BETTER_AUTH_URL from NEXT_PUBLIC_APP_URL realtime read BETTER_AUTH_URL directly and fell back to localhost while simstudio derived it from NEXT_PUBLIC_APP_URL, so setting only the public origin left realtime authenticating against http://localhost:3000. * fix(helm): deliver bundled REDIS_URL via ConfigMap so an operator value always wins Injecting REDIS_URL as an inline container env made it beat every envFrom source, so a REDIS_URL held in a pre-created Secret or synced by External Secrets was silently shadowed and traffic moved to a fresh in-cluster Redis. Kubernetes resolves duplicate envFrom keys by letting the last source win, so the bundled URL now ships as a ConfigMap listed before the app Secret. Any operator-supplied value overrides it without the chart needing to read it, which also removes the redis.provideUrl flag the previous attempt required. * docs(helm): spell out the egress rule external datastores need The default NetworkPolicy allows 443 plus the bundled Postgres and Redis by pod selector. Anything you run outside the chart on another port needs its own rule, which is easiest to miss when REDIS_URL arrives via a Secret the chart cannot inspect. Adds a copyable example to the production checklist and the security guide. * feat(helm): add networkPolicy.allowExternalEgress for managed datastores The default policy allows 443 plus the bundled Postgres and Redis by pod selector, so a managed datastore on another port needs a hand-written CIDR rule — awkward when REDIS_URL arrives via a Secret the chart cannot inspect. Adds an opt-in switch that drops the port restriction while still blocking the cloud metadata endpoints. Defaults to false, keeping this chart stricter than the common chart default of unrestricted egress.
8.6 KiB
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 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, 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
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.
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.
