LibreFang

LibreFang is an open-source Agent Operating System written in Rust. It provides full lifecycle management for AI agents — from creation and scheduling to communication and deployment — with 49 LLM drivers, 44 channel adapters connecting platforms like Telegram, Discord, Slack, and WeChat, plus MCP and A2A protocols for inter-agent collaboration.

Manage agents via CLI or the web dashboard, configure workflows and cron jobs, and let agents autonomously browse the web, call APIs, and run commands through Hands. All operations are protected by 16 layers of security with RBAC and audit logging.
