Hi everyone,

I’ve just released JelliNet, an open-source tool I developed for Unreal Engine multiplayer projects.

It consists of two connected applications:

JelliNet Insight (App): Analyze logs generated by the Logger. Visualize function calls per actor, explore details, and even get experimental optimization suggestions.

JelliNet Logger (UE5 Plugin): Capture replicated function calls during multiplayer sessions in real-time. Makes debugging replication issues easier.

With these tools, you can log multiplayer activity and analyze it efficiently.

Check them out on GitHub:

Developed by me. Fully open-source. Feedback, contributions, and stars are welcome!
