Sim is the collaborative workspace to build, deploy, and monitor AI agents and workflows. Used by 100,000+ builders.
Sim is an open-source, self-hostable AI agent workspace built with Next.js and TypeScript that lets teams design, run, and manage multi-step agent workflows through three distinct interfaces: a natural-language chat called Mothership, a visual block-based canvas called Workflows, and a code editor. It connects to over 1,000 integrations and supports every major LLM provider, including Claude via the Anthropic API, alongside OpenAI, Gemini, and DeepSeek. Agents can be grounded in uploaded documents through a built-in knowledge base, and structured data can be stored and queried using a native Tables feature with typed columns. A Copilot assistant can generate workflow blocks, wire variables, and debug errors from plain-language instructions. The platform is available as a cloud service at sim.ai or self-hosted via Docker Compose, with the latter requiring at least 12 GB of RAM. Teams automating multi-agent pipelines who need a single workspace to combine RAG, structured data, and LLM routing will find the most use here.
Open-source platform to build, deploy and orchestrate AI agents with 1000+ integrations and LLMs.

Create or update a Sim integration block with correct subBlocks, conditions, dependsOn, modes, canonicalParamId usage, outputs, and tool wiring. Use when working on `apps/sim/blocks/blocks/{service}.ts` or aligning a block with its tools.
Add or update a Sim knowledge base connector for syncing documents from an external source, including auth mode, config fields, pagination, document mapping, tags, and registry wiring. Use when working in `apps/sim/connectors/{service}/` or adding a new external document source.
Add a code-defined table enrichment (registry entry) under `apps/sim/enrichments/` backed by an ordered provider cascade, ensuring every provider tool it calls has hosted-key support. Use when adding a per-row table enrichment that fills cells via existing Sim tools.
Add hosted API key support to a tool so Sim provides the key (metered and billed to the workspace) when a user has not brought their own. Use when adding a `hosting` config to a tool under `apps/sim/tools/{service}/`.
Add a complete Sim integration from API docs, covering tools, block, icon, optional triggers, registrations, resolved-secret/model-input safety, and integration conventions. Use when introducing a new service under `apps/sim/tools`, `apps/sim/blocks`, and `apps/sim/triggers`.
Add a new LLM model to apps/sim/providers/models.ts with specs verified against the provider's live API docs (no hallucination)
Run all code quality skills — effects, memo, callbacks, state, React Query, emcn design review, url-state, and comments — analyzing in parallel, then applying fixes sequentially
Spawn parallel task agents to explore a given area of the codebase from multiple angles, then use their findings to answer the question or build a plan. Use when a task needs broad fan-out exploration across many files before acting.
Review UI code for alignment with the emcn design system — components, tokens, patterns, and conventions
Review PRs and diffs for unbounded memory loading, concurrency explosions, oversized payload materialization, and missing pagination or byte caps. Use when reviewing cleanup jobs, background jobs, data imports/exports, file parsing, API fan-out, workflow execution payloads, large arrays/files, or any change that reads many rows, files, responses, logs, or external API pages into process memory.
Audit React Query usage for best practices — key factories, staleTime, mutations, and server state ownership
Commit, push, and open a PR to staging in one shot — runs the cleanup pass and, when migrations changed, the db-migrate safety review first
Validate an existing knowledge base connector against its service's API docs
Validate an existing Sim integration (tools, block, registry, and resolved-secret/model-input boundaries) against the service's API docs and Sim execution conventions
Validate a model entry (or every model in a provider) in apps/sim/providers/models.ts against the provider's live API docs (no hallucination — reports what cannot be verified)
Validate an existing Sim webhook trigger against provider API docs and repository conventions
Analyze and fix unnecessary useState, derived state, and server-state-in-local-state anti-patterns
Install, upgrade, and operate the Sim Helm chart on Kubernetes. Covers install path selection (inline / existingSecret / External Secrets Operator), required secret generation, the values.yaml mental model (env vs envDefaults vs Secret), and common failure triage. Invoke when a user asks about deploying Sim to a cluster, authoring a Sim values.yaml, debugging a Sim pod that won't start, upgrading a Sim release, or wiring Sim into a secret manager.
Author or review a Drizzle DB migration for zero-downtime safety — expand/contract phasing, backward-compatibility with the deployed app version, and writing the `-- migration-safe` acknowledgment the check:migrations lint requires. Use when adding/editing files under `packages/db/migrations/` or changing `packages/db/schema.ts`.

## Self-hosting
**Requirements:** [Node.js 20+](https://nodejs.org/) and [Docker](https://www.docker.com/).
`npx sim-setup` is an interactive wizard that creates a small `sim/` deployment directory, provisions the database, generates secrets, writes `.env`, connects a Chat API key, and starts the published Sim images with Docker Compose. It does not clone the repository.
When it finishes, open [http://localhost:3000](http://localhost:3000).
Inside a cloned Sim repository, run `bun run sim-setup` to unlock the source-only local development and Kubernetes modes.
Reconfigure an optional capability without rerunning the full wizard:
```bash
npx sim-setup config
npx sim-setup add email
npx sim-setup add storage
npx sim-setup add sandbox
npx sim-setup add jobs
npx sim-setup add cache
npx sim-setup add knowledge
npx sim-setup add chat
npx sim-setup add llm
npx sim-setup add integration slack
```
`npx sim-setup config` 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 `npx sim-setup status`,
which reports whether installed services are running and healthy.
Manage your install from its directory:
```bash
npx sim-setup start | stop | restart # bring your install up / down / cycle
npx sim-setup update # pull and apply Compose images
npx sim-setup status # what's installed and healthy
npx sim-setup logs # follow logs
npx sim-setup doctor # diagnose configuration problems
npx sim-setup down # remove containers (data kept)
npx sim-setup reset # archive .env and wipe managed data
```
The setup package detects how you're running and acts accordingly. Use `--dir <path>` to create or manage a deployment somewhere other than `./sim`.
Sim also supports local models via [Ollama](https://ollama.ai) and [vLLM](https://docs.vllm.ai/). See the [self-hosting docs](https://docs.sim.ai/self-hosting/docker) for details.
## Chat API Keys
Chat is a Sim-managed service. `npx sim-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](https://sim.ai/selfhost/settings/chat-keys).
## Environment Variables
See the [environment variables reference](https://docs.sim.ai/self-hosting/environment-variables) for the full list, or [`apps/sim/.env.example`](apps/sim/.env.example) for defaults.
