Celeris Realtime - Realtime Infrastructure for Builders

Hey Product Hunt I'm David, a backend engineer who's spent years building realtime systems. Every live feature I shipped followed the same pattern. The feature took a week. Keeping WebSockets alive, handling reconnects, routing across nodes and surviving traffic spikes took months. Celeris handles that part. It's built in Rust, pushes 100K+ messages/sec per node, scales out horizontally, and keeps users connected through deploys. You publish, your users get the update. I'd love honest feedback, especially from anyone who's fought with realtime infra before. I'll be here all day.
