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!

Thank you all for the incredible feedback and thoughtful critique. It genuinely helped shape the direction of the project.

I've just published a detailed Road Map (https://github.com/efecan0/binaryrpc-framework/blob/main/Roa...) based on the discussions here. It includes core cleanup (bye bye Folly, hello absl), a modular transport layer, and better ergonomics for real-world apps.

This was my first open-source release and seeing it hit #1 on HN was surreal. I appreciate everyone who took the time to comment. If you're interested in helping shape the project further, feel free to join the discussion or file issues.

Thanks again — Efecan
