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

Why building the frontend is hard
If you’ve built any LLM or RAG (Retrieval‑Augmented Generation) application recently, you know the drill: hooking up the backend API (OpenAI, Anthropic, or local models) takes about 10 minutes.
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. The main challenges are:
- Streaming Text – Updating React state chunk by chunk without causing massive performance bottlenecks.
- Markdown Parsing – Rendering code blocks, bold text, and lists correctly on the fly.
- Auto‑scrolling – Keeping the chat pinned to the bottom as the AI generates long responses.
- Complex UI States – Handling loading, error, and typing indicators gracefully.
After doing this from scratch for the third time, I decided to build the exact UI component I wished existed—and open‑source it for the community.
