Is chatkit.js open source?

Hello,

The chatkit-js GitHub repo says ChatKit is Apache licensed, but all I can find there are the TypeScript types and a React wrapper. Is the underlying chatkit.js Web component from the CDN also open source and available somewhere, or is it closed source?

(sorry I tried to links but it wouldn’t allow me to, hopefully you can figure out what I’m talking about).

Thanks!

–Scott.

Short answer: only partially.

The ChatKit GitHub repo being Apache-licensed covers:

  • TypeScript types

  • The React wrapper / bindings

The Web Component served from the CDN is not published as source code in that repository, so it should be treated as closed-source / distributed-only, even though it’s publicly consumable.

This is a fairly common split:

  • OSS types + framework adapters

  • Proprietary compiled runtime delivered via CDN

If OpenAI decides to open-source the underlying Web Component, it would likely appear as a separate repo or be explicitly documented — but today there’s no public source for that part.

ok thanks, that’s what it looked like to me too, but wanted to make sure I wasn’t missing something. Have a happy new year!
