    About

    CrashDetector analyzes Minecraft crashes to help players identify their causes and, where possible, fix them without waiting for outside support. After a crash, it opens a customizable interface with results from more than 220 checks, including diagnoses for missing dependencies or classes, Java and memory problems, broken mod configurations, driver and OpenGL errors, incompatible mods, and corrupted files or worlds. Many detected problems have one-click QuickFixes, and an integrated relauncher can restart the game with additional diagnostic tools to collect information about harder-to-trace failures. The mod also includes mod-list history and comparisons, snapshots for tracking changes, and tools to view logs, share reports, or load logs from files and links. VTuber, anime, and idol contributors appear in the mod, and its interface and guidance are designed to make complex crash reports more approachable for both new and experienced players.

    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

    Accepts connections from other computers
    It can accept connections from other computers.
    Can download and run new code
    The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware.Not a Warning: we read its code and found no code downloaded over http or run without a check.
    Can update itself
    It can add or replace files in your mods folder, for example to update itself.
    Starts other programs
    It can start another program on your computer. It can open a web link or a file, run a command line, read system or hardware information, start a Java program, read graphics card information, stop a program and run a script interpreter.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Found: launcher files, your user folder, application data, your Documents and Downloads and the temporary files folder.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in the mod's own code and in code libraries built into it. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 16 files in your config folder.
    Shows AI features in its code
    The code calls an AI service over the internet, for example to write text or make images. It uses an AI service.

    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 · The latest file 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.
      1 latest file, for a recent version. 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
    • Accepts connections from other computers
      Runs a small web server.
    • Uses folders outside the game

    Sends crash reports and unknown data

    Sent to api.bitbucket.org, api.mclo.gs, api.modrinth.com, api.pastes.dev, asbestosstar.egoism.jp, waifu.neoforged.net and an address built while the game runs.

    We found this in its code, read without running it.

    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.

    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.

    Can use AI in the game

    Shows AI features in its code.

    We found this in its code, read without running it.

    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.
