LobeHub is the ultimate space for work and life: to find, build, and collaborate with agent teammates that grow with you.
Weโre building the worldโs first and largest humanโagent co-evolving network.
AI used to feel like magic. But for most people, that magic has remained out of reach โ locked behind closed ecosystems, expensive APIs, and tools that prioritize vendors over users. We started LobeHub because we believed it didn't have to be this way.
What began as LobeChat, an open-source chatbot framework, has since evolved into a comprehensive AI platform that gives individuals and teams the freedom to use any model, extend with plugins, and own their data. We don't think of LobeHub as just another AI tool โ we see it as a better way to interact with AI.

I'm 18M Indian. Growing up I've always been a daydreamer, if you may. Since 8th grade - I'm fascinated by programming. And I'm good at it too. But I'm not cocky too. I wouldn't say I'm at an advanced level, but I can most probably solve any problem - in time - with my skills. I also keep my skills brushed by solving problems on Hacker Rank (every day or alternate days) and try my best to contribute on... Source: almost 3 years ago
