Jean2 is an open-source, locally-hosted AI agent server that users can configure and extend with tools written in any language, connect to any LLM provider, and access from multiple client types. It's interesting because it combines a flexible, modular architecture (supporting MCP servers, hierarchical subagents, and sandboxed tools) with a strong focus on user control and avoidance of vendor lock-in.

Target audience: backend devs, devops
