Datastar is a lightweight hypermedia framework that enables building reactive, real-time web apps by shifting frontend state management to the backend using HTML attributes and server-sent events.

Why it matters: Datastar simplifies frontend complexity by driving UI reactivity from backend logic, reducing JavaScript overhead.

The big picture: It supports any backend language, embraces server-side rendering, and offers realtime collaboration without typical frontend framework bloat.

The stakes: Some users worry about potential performance issues over slow networks and the trade-offs of returning HTML-heavy responses versus JSON.

Commenters say: Opinions are mixed—some praise its elegance and engineering, while others criticize its approach, complexity for advanced tasks, paid features, and resemblance to existing tools like Hotwire or htmx.
