But.. SSE is limited to like 6 or so connections per browser, no?

Not with HTTP/2

With HTTP/1 the limit is 6 per domain per browser. With HTTP/2 the limit is negotiated between the server and client, 100 by default.

It's not a problem in practice, just ensure to use HTTP/2.

I'd also add even if for whatever reason you are on http1.1 (you should really use http2 for server driven apps there's a lot of other advantages). Datastar prunes connection based on the browser visibility API so on http1.1 a user would need 5-6 visible tabs/windows visible at the same time for you to hit any issues.

Assuming you are using Datastar the way I do with a single persistent SSE connection.

This feature is also much better for the battery life of devices and the server as you are only sending stuff if the user is there.
