Show HN: Persona.js – a vanilla-JS agent UI library with native WebMCP (MIT)

Appreciate the feedback and support so far!

Wanted to add, in terms of extensibility, we've really tried to make the key parts of the UX hookable. Most of what you see on this page like tool / reasoning calls, voice, loaders, approvals, etc are completely replaceable in a few lines of plain JS: https://www.persona-chat.dev/advanced.html

It means you can do interesting things like go straight to OpenAI or Elevenlabs voice for read-aloud while streaming the main chat from your framework.

I'd like to improve the shareability of what's created in the ecosystem, but we're not quite there yet.

If you have ideas for more hooks or extensions you'd like to see, we're very much in listening mode.

I really appreciate your work since I was looking for something similar, couldn't find any and eventually thought of making something of my own to integrate into my ongoing project!

Your solution is well advanced and provides lot of thing out of the box. Loved it!
