About

BotSharp is an open source C# framework on .NET for building AI bot platforms. Its plugin and pipeline design keeps components decoupled, and it provides built-in multi-agent conversations with state management, several LLM planning approaches, and vector-based memory search. The README also lists MCP integration, channel connectors for Facebook Messenger, Slack and Telegram, RESTful and WebSocket APIs, and a SvelteKit-based UI.

Use cases: agent-orchestration, team-chat
