Bumps next, @next/env and the @next/swc-* optional deps to 16.3.0 across the root overrides, apps/sim, apps/docs and packages/emcn. Two config notes worth keeping: - `experimental.turbopackFileSystemCacheForBuild`'s default flipped false -> true for stable in 16.3.0, so our explicit `false` is now load-bearing rather than defensive. Without it this bump would have silently re-enabled a build cache measured 3.2x slower on this codebase (#6078). Comment updated to say so. - `experimental.useTypeScriptCli: true` is now pinned. TypeScript 7 ships no JavaScript compiler API until 7.1, so Next's default checker cannot run and needs the project-local `tsc` CLI instead. 16.2.12 was silently skipping build-time type checking entirely because it detected @typescript/native-preview and short-circuited the stage ("Finished TypeScript in 138ms"); pinning the flag keeps that from drifting back. TypeScript toolchain cleanup that the upgrade makes possible: - Drop @typescript/native-preview from apps/sim and apps/docs. It was the pre-release channel for TS 7 and is superseded by typescript@7 (nightlies now ship as typescript@next), and its presence is what suppressed build type checks. - Align packages/browser-protocol and packages/terminal-protocol from typescript ^5.7.3 to ^7.0.2 so every workspace is on one compiler version. apps/sim keeps @typescript/typescript6 as a production dependency: the function sandbox at app/api/function/execute dynamically imports the TS 6 compiler API to transpile user code, and TS 7 has no API to replace it yet. Build and dev were benchmarked 3x per version on a byte-identical tree; the upgrade is performance-neutral (build median 100s -> 99s, dev:full warm 10s -> 9s).
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.
