Build, deploy, and orchestrate AI agents. Sim is the central intelligence layer for your AI workforce.
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.

git clone https://github.com/simstudioai/sim && cp sim/*.md ~/.claude/agents/23 items in this repository
Create a block configuration for a Sim integration with proper subBlocks, conditions, and tool wiring
Add a knowledge base connector for syncing documents from an external source
Add a code-defined table enrichment (registry entry) backed by a provider cascade, ensuring each provider tool has hosted-key support
Add hosted API key support to a tool so Sim provides the key when users don't bring their own. Use when adding hosted keys, BYOK support, hideWhenHosted, or hosted key pricing to a tool or block.
Add a complete integration to Sim (tools, block, icon, registration)
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 in sequence — effects, memo, callbacks, state, React Query, and emcn design review
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
Validate an existing knowledge base connector against its service's API docs
Validate an existing Sim integration (tools, block, registry) against the service's API docs
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 useCallback anti-patterns in your code
Analyze and fix useMemo/React.memo anti-patterns in your code
Analyze and fix useEffect anti-patterns in your code
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.

### Build everything in Mothership
Your AI command center. Describe what you want in plain language. Mothership knows your entire workspace and takes action: building agents, running them, querying data, and more.
<p align="center">
<img src="apps/sim/public/static/mothership.gif" alt="Mothership building and running an agent from chat" width="800"/>
</p>
### Create files and documents
Generate documents, reports, and presentations from a single prompt, grounded in your workspace data.
<p align="center">
<img src="apps/sim/public/static/files.gif" alt="Mothership generating a document from a prompt" width="800"/>
</p>
### Ground agents in your knowledge
Upload documents to a knowledge base and let agents answer questions from your own content.
<p align="center">
<img src="apps/sim/public/static/knowledge.gif" alt="Creating a knowledge base" width="460"/>
</p>
### Structured data with Tables
A database, built in. Store, query, and wire structured data into agent runs.
<p align="center">
<img src="apps/sim/public/static/tables.png" alt="Tables view with typed columns" width="800"/>
</p>
### Build visually with Workflows
Prefer a canvas? Design agents block by block in the visual builder, and let Copilot generate blocks, wire variables, and fix errors from natural language.

### Self-hosted: NPM Package
```bash
npx simstudio
```
→ http://localhost:3000
#### Note
Docker must be installed and running on your machine.
#### Options
| Flag | Description |
|------|-------------|
| `-p, --port <port>` | Port to run Sim on (default `3000`) |
| `--no-pull` | Skip pulling latest Docker images |
### Self-hosted: Docker Compose
```bash
git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d
```
Open [http://localhost:3000](http://localhost:3000)
Sim also supports local models via [Ollama](https://ollama.ai) and [vLLM](https://docs.vllm.ai/). See the [Docker self-hosting docs](https://docs.sim.ai/self-hosting/docker) for setup details.
### Self-hosted: Manual Setup
**Requirements:** [Bun](https://bun.sh/), [Node.js](https://nodejs.org/) v20+, PostgreSQL 12+ with [pgvector](https://github.com/pgvector/pgvector)
1. Clone and install:
```bash
git clone https://github.com/simstudioai/sim.git
cd sim
bun install
bun run prepare # Set up pre-commit hooks
```
2. Set up PostgreSQL with pgvector:
```bash
docker run --name simstudio-db -e POSTGRES_PASSWORD=your_password -e POSTGRES_DB=simstudio -p 5432:5432 -d pgvector/pgvector:pg17
```
Or install manually via the [pgvector guide](https://github.com/pgvector/pgvector#installation).
3. Configure environment:
```bash
cp apps/sim/.env.example apps/sim/.env
# Create your secrets
perl -i -pe "s/your_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_internal_api_secret/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_api_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
