LobeHub
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 | 2026-03-24You 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!

Imagine if operating systems, browsers, or databases had evolved with only closed systems. We wouldn’t have the internet we know today.
AI needs world-class open alternatives to great tech.
In response to this, we’ve been busy building Mindshub. A high quality, open-source AI coworker you can truly make your own. Where we know. Good enough wasn’t an option. You can check it out in
https://github.com/mindsdb/mindshub
Inspect it. Modify it. Extend it. Fork it. Make it uniquely yours. Call it Claudio if you want ;)
Choose any model, open or proprietary. Pick and customize the open-source agent that fits your workflow. Connect your own tools. Keep your data where you want it.
We’d love your feedback.
