7. LobeHub

   6 20 78,186 10.0 TypeScript

   The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you.

   

   Project mention: Show HN: AI Roundtable – Let 200 models debate your question | news.ycombinator.com | 2026-03-24

   You can set this up yourself with API keys to the corresponding providers and creating an Agent Group in https://github.com/lobehub/lobehub. Agent groups allow you to easily create a room of agents and have them discuss any of your topics. Easily make agents with types and skills, it even assists in drafting starting prompts and even team members depending what your query (and selected model) is.

   You can self-host as well, but not via desktop app. Sever setup required.

   Be careful of your token context, you can easily rack up costs if you leave Opus selected as the model and get lost in some rabbit hole of results.

   Enjoy enjoy!

Think of it as a ChatGPT replacement where the server runs on your machine. Licensed under Apache 2.0, with the full source on GitHub, it sits in the same category as LM Studio and Ollama, with a distinctly different philosophy: Jan wants to be the complete local AI platform, not just a runner or a chat UI.
