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:  
Insight → [https://github.com/mortemeyn/JelliNet-Insight](https://github.com/mortemeyn/JelliNet-Insight)  
Logger → [https://github.com/mortemeyn/JelliNet-Logger](https://github.com/mortemeyn/JelliNet-Logger)

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