Congrats on your project. Did you get to replace the old Java prototype you were using at work? It'd be interesting to see how the performance compares.

I’m a recent CS graduate. During the past few months I wrote BinaryRPC, an open-source RPC framework in modern C++20 focused on low-latency, binary WebSocket messaging.
Why I built it * Wanted first-class session support, pluggable QoS levels and a simple middleware chain (global, specific, multi handler) without extra JSON/XML parsing. * Easy developer experience
A quick feature list * Binary WebSocket frames – minimal overhead * Built-in session layer (login / reconnect / heartbeat) * QoS1 / QoS2 with automatic ACK & retry * Plugin system – rooms, msgpack, etc. can be added in one line * Thread-safe core: RAII + folly
Still early (solo project), so any feedback on design, concurrency model or missing must-have features would help a lot.
Thanks for reading!

Informally, on the same hardware and traffic pattern we see:
• noticeable CPU head-room • lower p95 latency • higher peak throughput
Once I have a full week of numbers cleaned up, I’ll add a short performance section to the README and post the graphs. Thanks for the interest stay tuned.
