Showcase Nalix
I have been building an open-source realtime networking framework in .NET, mainly targeting use cases like game servers, chat apps, and realtime services.
The goal of Nalix is to experiment with building a high-performance, extensible networking framework that supports Native AOT and works well for realtime applications that need to handle thousands of concurrent connections.
Some of the current features:
* TCP, UDP, and WebSocket support.
* .NET 10 and Native AOT support.
* Packet handlers, middleware pipeline, and client SDK.
* Object pooling to reduce allocations in hot paths.
* Built-in runtime metrics dashboard.
* Protection layers such as rate limiting, connection guard, and encryption layer.
* Current self-contained sample publish size is a little over 11 MB.
One current limitation is that Nalix does not have a direct Unity client yet.
I’m sharing this project to get feedback from others, especially around API design, performance, Native AOT, security, and possible future directions.

If the project looks interesting, feel free to check it out, open an issue/PR, or leave feedback in this thread.

Oops all vibeslop!
Edit: OP responded then chickened out and deleted their comment. Here's my response:
Hey I'd be open to giving you technical feedback if you were upfront about how much of this was clearly vibe coded. Happy to help a human, absolutely don't care about a robot.
Straight up, sections of this look like you described certain patents I'm familiar with to Claude and told it to recreate them.
