Detail headers disagreed on where Delete sits. The skills page reads
`Share → Delete → Discard → Save`, but every SettingsPanel page spread
saveDiscardActions() first and appended Delete, rendering it to the RIGHT of
the primary chip: sandboxes, custom tools, custom blocks, permission groups and
data retention all did this.
Fixed in the shell rather than at nine callsites. orderHeaderActions() ranks
actions — secondary, then `id:'discard'`, then `variant:'primary'` — stably
within each band, so writing the array the natural way now produces the right
header and a new detail page cannot get it wrong. This generalizes past Save:
workflow MCP servers' `Add workflows` primary is now right-most with Delete
before it, instead of the reverse.
The ranking has to survive one trap. The shell routes onSelect through
configRef.current.actions[index] to avoid stale closures, so reordering the
render without preserving the source index would bind every chip to the wrong
handler — clicking Delete would Save. orderHeaderActions carries {action,index}
pairs; settings-header-shell.test.tsx pins that at the render level, including
the conditional-Discard case where a missing action shifts every index.
Delete is also now a plain chip on the nine resource-detail headers, matching
skills, each with a stable `id:'delete'` (three lacked one, so the chip
remounted when its label flipped to Deleting...). `variant:'destructive'` is
kept for actions destructive at scale — Delete all passwords, Clear all
browsing data, Sign out all members — which the confirm modal does not cover
the way it covers removing the single resource you are looking at.
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.
