    About

    ServerWarashi is a server administration mod for diagnosing tick performance problems and managing risky chunk loading. Its on-demand reports break down estimated tick costs across chunks, entities, block entities, natural spawning, server tasks, event handling, and garbage collection, with MSPT, peak time, sample counts, coordinates, and loading-source details. With Xaero's World Map, administrators can view live chunk-performance heatmaps, weak-loading risks, loader coverage and activity, and off-screen danger directions; an in-world overlay can also mark entity, dropped-item, and block-entity hotspots with flame effects and timing labels, and highlight risky chunks with beams. The mod scans tracked chunks for entity-dense areas, estimates their main entity and item types, and lets operators submit confirmed cleanup jobs that remove targets in batches over multiple ticks. Operators can freeze supported block chunk loaders while retaining their tickets, so their chunks stop regular entity and block ticking; saved freeze policies also apply to later tickets from the same loader. An entity-load safeguard can limit extreme batches by retaining a configured number of entities from the most numerous types and deleting the rest, while dedicated-server watchdog reports can include chunk-ticket owners, coverage, and associated entity and block-entity counts.

    Written from CurseForge and the GitHub README . How we write it

    In-game changes

    Changes the game's code in 3 areas: Server and world logicChanges 5 game code files in this area: the world, commands, scoreboards, saved data and game rules., Chunk loading and storageChanges 4 game code files in this area: how the game loads, tracks, saves and unloads chunks. and Mobs and their behaviorChanges 2 game code files in this area: mobs, animals, villagers, projectiles and how they move and act..

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Forge 1.20.1. See Privacy

    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 · Both latest files checked, last on 17 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.
      2 latest files: the newest file for each Minecraft version and loader. Both are 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
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    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.

    How we checked · Both files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of both files, for recent Minecraft versions. See each file in Releases

    AI

    No sign so far that AI was used to make it

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

    We have not read its code history yet.

    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.
