Sim is a platform for building, deploying, and managing AI agents with support for multiple LLM providers including OpenAI, Anthropic, Gemini, and DeepSeek. It provides both low-code and no-code interfaces built with Next.js and React, allowing developers to create agent workflows, orchestrate multi-agent systems, and integrate RAG capabilities without extensive backend work. Developers would use Sim to reduce boilerplate when building agentic applications, manage complex agent interactions at scale, and quickly prototype or deploy AI-powered automation and chatbot systems.
