    About

    Crash Assistant is a client-side troubleshooting mod that opens a GUI after Minecraft crashes, including early startup failures, and gathers available game and launcher logs, crash reports, and JVM error files in one place. It analyzes logs for known problems and presents explanations and repair guidance, covering issues such as missing or conflicting mod dependencies, duplicated mods, Mixin errors, memory exhaustion, GPU and driver problems, and corrupted installations. For some diagnoses it offers one-click fixes, such as locating incompatible Create or Epic Fight addons, finding mods that rely on a missing class, or addressing certain launcher and mapping problems. The GUI also includes tools to identify MCreator-made mods, search mods for a Java class or package, and inspect which mods depend on a class or package; it can warn when Minecraft is using integrated graphics despite a dedicated GPU being available. Users can drag and drop log files, or explicitly upload available logs to mclo.gs and copy a shareable link with a message formatted for reporting; uploads occur only after the user chooses to upload. For modpack support, it can direct players to a configured help community and track mod-list changes, including which mods a player added, removed, or updated relative to the pack.

    No harmful code found

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

    What it can do on your computer

    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. Found in the mod's own code and in app, a packed file the mod does not list.
    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 app, a packed file the mod does not list. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 7 files 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 45 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.
      45 latest files: the newest file for each Minecraft version and loader. The answer above is about the 15 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
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.

    Privacy

    Sends unknown data

    Sent to api.curseforge.com and api.modrinth.com.

    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.

    How we checked · All 15 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.

    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
      Nothing about you
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      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, code history and pull requests 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.
