Overview
Sim Studio builds a visual platform to create, deploy, and manage large language model (LLM) workflows. Its core product Sim provides a drag-and-drop, node-based interface to connect 100+ tools and models (including OpenAI, Anthropic, and Gemini) for designing AI agents, with Sim handling the orchestration. It differentiates itself with a Figma-like visual design, an open-source self-hosted option under Apache-2.0, and an approach that combines MLOps, workflow automation, and AI orchestration in one platform, available as cloud or self-hosted deployments. Goal: help software teams prototype, validate, and scale AI-powered systems quickly and visually.
