Building AI Chat Interfaces is Exhausting. So I Open-Sourced a Solution.

But building the frontend? That’s a completely different story. 😅 As a full-stack developer working heavily with AI architectures, I found myself constantly rewriting the same chat interfaces. You have to handle: Streaming Text: Updating React state chunk by chunk without causing massive performance bottlenecks.
