Cool stuff!

Btw if you build a wingman AG-UI adapter the Channels SDK would just work with it. Nowadays, you can honestly get this done in probably less than a day of work --we've got a pretty good factory set up with validators and tests, etc.

Happy to help if interested!

Not necessarily wrong, but that's just a maturity problem on our end right now. We're aiming to take the same approach as our web SDKs: it works great for open-source deployments and works even better with Enterprise Intelligence. We had some back-and-forth over webhook vs. WebSocket in the last two weeks that caused some churn on our side.

If you point your agent at our SDKs, they should help you use the Slack or Teams adapters directly without leveraging the hosted service: https://github.com/CopilotKit/CopilotKit/tree/main/packages/...

Delivering AG-UI with generative UI to Slack and Teams should work great with the open-source packages. We'll make these interfaces better and more intuitive.

I like the idea of having a much easier way to integrate with all of the chat clients, especially with UI. I've been surprised there wasn't a way to do that more easily before (even pre AI agent revolution).

Two points of confusion that I wanted to bring up just so you know what it was like for me as a new reader: "Copilot" is unfortunately an extremely overloaded term right now. Not your fault, but I don't know about CopilotKit, so I was trying to figure out who really was behind this. (Is it Microsoft? etc) I also (like another poster) wondered if I needed your server in order to use this. I love the MIT license, but it wasn't clear to me if this was just a veneer over a closed-source thing or not. I saw in your response that there is a legit open source ability to use it, but that wasn't clear.

I saw WhatsApp listed but I can't find how the integration works?

From quick glance I don’t think so that’s the case. copliotkit promises ag-ui compatiblity., which means it can work with codex cli, mastra, pi, claude agents sdk and other harnesses as well (there are ag ui adapters as well). I’m actually integrating this with claude agent sdk with ag ui adapter., which i don’t think is possible with vercel chat sdk.

Not proprietary and not a wrapper. Chat SDK served as inspiration, of course, but I think it misses a few hard parts of bringing agents to chat interfaces:

- Generative UI in these surfaces needs to be durable. If your agent composes a Block Kit or Adaptive Cards interface with interactivity, you have to be ready to handle that interactivity weeks later. We handle this with our JSX renderer.

- Chat interfaces are inherently multiplayer. The worst thing you can do is have your agent act like a bot: posting all of the time, creating noise, and offering no customization. I think Claude Tag nailed the user experience here, and now we want to empower developers to create agents with a similar UX via open source.

- Truly agent-and-surface agnostic. We're fully powered by AG-UI (ag-ui.com), so you can bring any agent into Slack and then take that same agent to web or mobile all over the same protocol.
