Sim (formerly Sim Studio) is an open-source AI agent platform where you build, deploy, and orchestrate agents on a lightweight visual canvas by connecting blocks, or conversationally and via code. It supports 15+ LLM providers and explicitly documents Bring Your Own Key: "you can use your own API keys at base provider pricing with no markup." Users plug in their own keys for OpenAI, Anthropic, Google Gemini, Mistral, xAI Grok, Groq, DeepSeek, OpenRouter, Cohere, Fireworks, and others, and can point at self-hosted OpenAI-compatible endpoints via Ollama (OLLAMA_URL), vLLM (VLLM_BASE_URL), and LiteLLM (LITELLM_BASE_URL), plus Azure OpenAI/Anthropic endpoints. It runs as a hosted cloud product (free Community tier with paid Pro/Max/Enterprise) or fully self-hosted via `npx simstudio` or Docker Compose, requiring PostgreSQL with pgvector. Apache-2.0 licensed, ~28k GitHub stars, very actively maintained (v0.7.10 released June 2026, 5,000+ commits).

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
