What it is
BotSharp is an AI multi-agent framework built on the .NET platform. It enables developers to create complex, intelligent systems by leveraging multiple agents that can interact with each other and external environments.
BotSharp stands out by providing a robust .NET framework specifically designed for multi-agent systems, offering developers the flexibility to build complex interactions and behaviors without being constrained by cloud limitations.
