I dont think it s really open source, the MIT part is just the client. The service that actually makes it run is closed and license-gated.

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.
