* improvement(files): cache stream binding meta, tighten file cache-control, prune dead persist path - Cache the agent-stream ProseMirror↔Yjs binding metadata per session and reuse it across streamed frames instead of rebuilding it (O(doc)) every frame; matches how y-tiptap's own binding maintains the mapping in place. Safe because the shadow doc only ever sees the agent's own reconciles. - Default createFileResponse to a private, no-cache policy so auth-gated bytes are never stored in a shared cache; genuinely-public serve routes opt into public caching explicitly. - Serve content-addressed (key=) embedded images with an immutable private cache to avoid re-downloading them on every doc re-open; fileId= embeds and public shares keep revalidating (the underlying key can change / a share can be revoked). - Drop the dead conflict.version field from the collab-doc persist result and remove the wasted getWorkspaceFile re-read on the conflict path (the relay treats missing and conflict identically and never read version). - Decorate-sort the files/folders lists (compute each sort key once) and index the move-menu subtree build (O(N) vs O(N^2)); ordering is preserved exactly. * fix(files): serve inline images with no-cache so deletion/authorization is enforced per request Embedded images are authenticated content whose backing file can be deleted or have its access revoked at any time. Both key= and fileId= embeds serve private, no-cache, must-revalidate, so every request re-runs the server-side deletion/authorization check instead of serving a possibly-stale image from cache.
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.
