    About

    Krypton Reno is a network-optimization mod ported from Krypton Fabric, with additional optimizations aimed at improving performance and scalability on supported modded systems. Its optimizations include more efficient packet encoding and entity tracking, reduced particle traffic, lower allocation and lock contention in connections, and options to move login, text-filtering, and download work onto virtual threads. Server-side culling can suppress occluded display and hanging entities, particles, and unnecessary block or lighting data in chunk packets, while packet compression is configurable. On the client, it supports RFC 8305 Happy Eyeballs, which races IPv4 and IPv6 connection attempts; most features can work when the other end does not have the mod installed. Native acceleration uses RecastLib on Windows x64 and arm64, while Velocity Native covers Linux x64 and arm64 and Apple Silicon, complementing one another across those platforms. Many behaviors can be adjusted in the configuration, including packet compression, culling, and Happy Eyeballs, and most runtime options take effect after reloading the configuration.

    What it can do on your computer

    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Found in velocity-native, a library it includes.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. No web address is written in its code. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 19 latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      19 latest files: the newest file for each Minecraft version and loader. The answer above is about the 14 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases

    Privacy

    We found nothing it sends about you

    We read its code without running it: it contacts 2 web addresses while you play.

    Like any connection, each address it contacts sees your IP address.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and code history and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
