Hi HN,

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!

Hi everyone, thanks for checking out BinaryRPC!

I built this project because I needed a simple but fast WebSocket-based RPC layer for my own real-time side projects. Existing options felt heavy or JSON-only, so I wrote something binary-focused and plugin-friendly.

I’d really appreciate any feedback on:

• Overall architecture / design smells • Concurrency model (thread-pool vs async IO) • “Must-have” features before this is production-ready

Design notes and a 5-minute chat-server demo are in this short post: https://medium.com/@efecanerdem0907/building-a-chat-server-i...

Any comments, suggestions or PRs are welcome. Thanks again!
