CrashDetector

THIS HAS BEEN IN EARLY ACCESS(BETA) SINCE APRIL. WE HOPE TO LEAVE EARLY ACCESS FOR GENERAL RELEASE IN  ̶A̶P̶R̶I̶L̶ JUNE 2026,BUT HAVE NO PROBLEM DELAYING THIS IF WE DECIDE WE WANT MORE FEATURES. WE WELCOME YOUR FEEDBACK THE PREFERRED WAY WE HAVE FOR SETTLING DISPUTES IS CURSEFORGE DMS, IF YOU HAVE A DISPUTE AND PROOF WE WILL HAPPILY LOOK AT IT AND MAKE CHANGES IF NEEDED.

This mod tells you why the game crashed! We can realistically help with over 75% of the most common crashes for custom modlists and over 95% of crashes for premade modpacks with over 200 common checks which are a mix of static and dynamic checks covering the most common and curated issues in Minecraft Modding as well as many lesser known ones and has QuickFixes to fix many in a click of a button making us the most powerful Crash Analyser for Minecraft as well as one of the easiest to use. It opens up after a crash to tell you the results on our highly customisable and changeable GUI. All this was made possible by the VTubers, Animes, and Idols who worked with us to help fight crashes and gave us expert advice in their stream and videos on the most common Minecraft Crashes and who also show up in the mod to help you! Most of our features work no matter which launcher you use, and if you launcher has some defect, we often have ways around them allowing you to solve errors which would otherwise not be solvable without special tools! We also have a relauncher built right in so you can relaunch the game with custom tools to get even more important info that even Dev launchers do not have. We have tools for both beginners and advanced users. Our main GUI puts the action right in front of you in a user friendly manner making It Easy for you to see the cause unlike other crash analysers which tend to make seeing the reasons secondary.It takes more advanced issues and makes them accessible to everyone. Crash Analysers have proven to be more powerful than the crash analysers without vtubers. No More needing to rely on human support (Which can take a long time and may never answer),but if our Mod cannot solve your issue automatically or you do not understand how to fix It or have other issues we invite you to use the Discord and QQ support links where we Will HAPPILY help you solve the issue and improve the Mod for future players.Our support channel Is nonjudgemental and einstellung-accommodating whenever possible, we will try our Best to help you solve your problem in the way YOU want rather than demanding you do things our way like some support channels demand. If you are making a publicly distributed modpack we can Also write patches to make It so Mods which would otherwise not Work together can Work.

It looks for

Features

• Works on ModLauncher (MCForge , NeoForge , PillowMC and derivatives) 1.7.10+, FabricMC, FeatureCreep (1.20.6+),Rift,LiteLoader (1.7.10),Bukkit/Spigot/Paper/Foliage,Meddle,ØLoader (NilLoader), often loading very early so we can see very early errors not seen by other analysers. We start a PID Monitor (MonitorDePID) to make sure we can analyse hard and sudden crashes.
• Free and Open Source, not protected by intellectual property. We help with forks! If Pagure.io(Fedora/RedHat) is Down I can send you a zip.
• Supports Español, English, Arabic, Portuguese, Russian, Chinese, Persian, Korean, Japanese, Esperanto,Vietnamese,Khmer,Thai,Swahili,Lao,Bahasa Indonesia,Bahasa Melayu,French (Burkina Faso),Ukrainian (Makhnovshchina), and more. You can add new languages easily in the developer extention API. You can also Override existing languages if you want to change some of the messages.
• Edit CrashDetector Config in GUI
• Customisable Main GUI based on HTML that modpack editors can customise (just go to crash_detector/pantilla.htm and edit it keeping the contents inside {})
• Edit other GUIs with our GUI editor in the Config called CDSkinCape
• Shows where your logs are
• Ability to share your report with links to logs using various logging APIs and sites such as securelogger.net (The Default, trusted by Dev Focused Launchers),securelogger.top (SecureLogger in Duetchland, EU hosted by Hetzner for GDPR),ruzone.securelogger.net(SecureLogger hosted in Russia), mclo.gs, paste.mikumikudance.jp,pastes.dev,CDPaste, mclo.gs with gnomebot.dev wrapper (not recommended) and other logging sites which are supported by the APIs for MCLogs API and stikked by editing the config file in the crash_detector folder. Many (SecureLogger,pastes.dev,CDPaste) use GZip tech to make it so large logs are still possible to send even if they would otherwise not be.
• Client side log anonymising is in beta but on by default, it will remove sensitive info such as access tokens, UUIDs, usernames, and IPs before they are even uploaded to the log site. This is still in beta though so issues may exist.
• Instance/Modpack sharing option to share your mods, configs, and other files with a support person easily
• Rememberance for V-Tubers
• When it is June there is a rainbow message for Pride Month at the top
• Ability to sideload logs from your own computer or other sources
• Ability to read logs from links in Markdown (such as Discord or QQ or Slack or AI or Crash Assistant) messages
• MCreator Mod Scanner
• Ability to look for mods with missing classes using NeoForge Waifu's API (1 search a minute)
• Ablity to search for field and method references in all your mods with Mods Tree or GrepR
• Ability to view the structure of all your mods including Jar in Jar and Classes and Methods and Fields witj Mods Tree.
• Log Viewer UI with colours and a background that is based on holotalk
• Ability to add custom crash reasons via JSON
• GUI for creating the JSONS with custom crash reasons
• Mods History functionality which keeps track of the mods the user has had since installing CrashDetector as well as a compare function to allow you to compare modlists to eachother, they have indications to show wheather they were a pass or fail or snapshot. It has a snapshot functionality to mark certain runs as snapshots to be compared to, this is good if you are a modpack and want to compare changes the user has made compared to your original modpack, can also be good for modpacks
• An extension system to make your own extensions to add more functionality to CrashDetector, look at this interface for details.
• Profiler
• Sampler
• Relauncher
• Multilingual Mods Search with CDMods
• grepr/fgrepr functionality which can search in jars correctly and works on Windows allowing you to find which mod contains a string.
• ProxySysOutSysErr is a tool we got from VShojo allowing us to get System.out and System.err even when many launchers do not provide it easily
• Alternate GUI system where if there is more than 1 variation of a Dialogue you can switch to it. You can also write your own with our developer extension API
• Console to see CrashDetector and Extenions possible Errors
• Patch System to patch some common mod errors (Does not work on Bukkit/Spigot/Paper/Foliage or older versions of MCForge)
• Warrent Canary Searcher
• Warning if we detect you write text in corperate settings not in compliance with The Pyongyang Cultural Language Protection Act (Korean Only)
• Open Source Report Endpoint and Pastebin Endpoint which you can host which is optimised for Large Minecraft Logs
• CFR Integration for Code Viewer
• Works with other crash Analysers such as NotEnoughCrashes and CrashUtilities
• Integration with MixerLogger
• SpongeMixin Explorer GUI
• Dependency Map
• Malware Scanner and Phishing / P2W Server scanner called CD Guard with a few common types of malware such as Fracturiser, BrightSDK, and Common Discord InfoStealers. We use deep analysis using our Buscardor (Finder). It also lets you download definitions for problematic servers, mostly from the CIS , which is a region Mojang does not pay as much attention to. We get the data from a launcher popular in the CIS.
• JGit Integration which will allow for users to  back up their instances and worlds and revert and share changes and play across devices and even add remotes or create them with Pagure,GitHub,Gitea/Forgejo,BitBucket,Beanstalk,and GitLab API integration planned , including self hosted forges. Right now only a limited subset of Pagure is supported for remote. For local you still need a traditional git client to edit much. This is still WIP

PLANNED CONTENT

• Loading cursor to show loading.
• More VTubers, go back and update many of the older GUIs to fit the theme better and look nicer.
• Fewer false positives
• More analysises. We are renting servers now to run mods against eachother to look for more errors and incompatibilities.
• Being an addon for JVM Based Launchers
• Improving performance
• Improved Neoforge support
• Improved Java 8 Support of old versions of the game
• Limited support on 1.7.3b-1.7.2 MCForge
• M3L support
• hmod support
• Risugamis Modloader support (However agent is still required if you need patches)
• KB4515384 Windows Update warning
• Spectre and Meltdown Warnings
• QuickFixes for setting GPU to a better one if it is detected you are using a lesser one
• Mini games for when you are waiting for something
• Optional NonArtistic NonCreative NonGenerative AnalysisOnly Baidu AI Integration with open source data  to help some people who want to use it to better understand their reasons and find things which our built in verificaciones cannot catch. This will most likely just be a website you can visit rather than something running on your computer. We will make sure this is not infringing on any ones rights,mostly training on some of CrashDetectors code and information i type in and translate to chinese which the AI will consider based on my knowledge from reading crashes, and will have safe guards in place to prevent the AI from generating images or generating content as these things are not needed and create polarisation of the community, it will only be optimised to read crashes and nothing else and told to avoid many false positives.
• Virus Total or MetaDefender scan option in CD Guard depending on whats better for Jar files
• Expand Folder mods to also exist for old MinecraftForge versions (Older versions like 1.6.4 MinecraftForge could load mods from folders (and some mods like millenaire did this back in the day), right now Folder Mod Support is mostly for JBoss Modules/JBoss Forge Furnace/FeatureCreep folder mods which still do have folder mods)
• World Backup
• More Modpack Formats (like Packwitz,CursePack,mrpack (both bbsmc and modrinth), and Launcher Specific pack formats) for Modpack/Instance Sharing
• More File Sharing Sites for Instance Sharing as well as a P2P sharing option.
• Performance Optimiser, which will suggest the best mods and config options for your computer, like a nightcore remix for your game.
• 1 click GPU Setter to set optimal GPU settings to Improve Performance
• More Alternate GUIs built in so you could choose which GUI best fits you.
• Primitive Mode which will skip directly to the share dialogue which will just be a button to share everything or go to normal mode with an optional error report dialogue. This will not be the default, it will only  be an option for coperate users/modpack who want CD to be a streamlined reporting tool simple for reporting rather than having your users dig themselves out.

It still needs some testing and some more real world use and some beautification but it should eventually be possible to have a stacktrace reader like this one.

Advantages for Players
■ Ability to know why the game crashed without knowing how to read logs
■ Ability to read these logs locally in seconds without needing to wait Many minutes hopeing for some tech support person to help you only If you speak English or whatever other Small Selection of languages they can speak 
■ Covers all the most common Crash types and Many rarer ones which even Many experienced people May not know
■ Ability to seamlessly and securly share logs in as few as 2 clicks if you need to ask a human for support■
■ Minimal English Required

You do not need to be a power user, CrashDetector is designed so wheather you are a a first day computer user or tech wiz you can fix your crashes and understand the errors. CrashDetector is designed to be the solution for all modders by making traditionally hard topics easy allowing you to in the future learn more advanced tech such as VisualVM or Eclipse IDE.


Advantages for VTubers
■ Ability to better help your fans get the game working
■ Customisable in your own image, designed for changing colours and vtuber pictures With our customisation GUI called CDSkinCape
■ Makes setting up a Minecraft project easier and less stressful
■ If you want a functionality we Will add It or do all the work to fork a versión of the Mod just for you and your fanbase

■ Add custom Crash reasons for your project specifically
■ Warn people of problematic launchers and Mods,including Mods which do not Work well or cheat Mods. The lists are fully customisable by you 
■ Ability to add antipiracy warning if you are afraid of harm to your reputation,but even then the analyser should be able to find the real problem most of the Time without them asking for support

We need your Help!

We have been running into issues finding new checks as most of the public support channels our VTuber allies get the crash reasons from are flooded with the same issues over and over again from other crash analysers without VTubers which we can already solve meaning it can sometimes take hours to find crash reasons we cannot already find. When you request support from our support team you are giving us crash reasons we would otherwise need to look hours for and get your crash fixed and save future players' time.

Notes:

This is untested on quilt-loader and QSLs logging library.

If the game crashes really early you may need to paste your log.

Currently Java 8 Development ModLauncher (in our case we officially targetted 1.13-1.16.5 but older versions could work) is halted, however we still compile against Java 8 so  on Fabric and Non-ModLauncher/MCForge versions of FeatureCreep it should still work on any version but are not marked as such on CF, the issue was with keeping CPWModLauncher, MCForge ModLauncher, and Pre-1.17 Modlauncher all in the same ITransformationService had a source level issue as well as the below issues. The isue is only source level, so it would not be hard to fix at a binary level and we plan to do this soon.

On Java 8 (common on 1.16.5 and before) on the Vanilla Launcher and many similar launchers the sharing of reports on the official endpoint does not work due to an SSL error common in old builds on Java 8. This is a similar reason why many old builds of java cannot be used on MCForge installers. 

On Java 8 (common on 1.16.5 and before) some of the methods of scanning the process and finding Java binary are unreliable. I am planning on increasing reliablity though. It has been tested though on 1.16.5 MCForge on MacOS 10.14 Mojave.

Search For Strings In Folders on Windows, including binary files

Ability to Securly share logs and analysis results in as little as 2 clicks with customisation and control over your logs. With securelogger, pastes.dev,CDPaste, and some others,we use GZipping Technology which allows you to send logs you normally could not send on Discord due to their large size. 

Log Reader so you can see where the errors are in the logs.

Buscardor (Finder)

Our Finder is influenced by the MacOS finder and is an internal tool used by the verifcaciones plus many advanced analysises in the mod to inspect the internals of the mods to get information and find problematic mods. Internally it uses ZipInputStream, Modloader Meta Data files (modules.xml, .mod files ,mods.toml,neoforge.mods.toml,fabric.mod.json, MANIFEST.MF, and more), ASM (Comes with Minecraft) and javassist.bytecode to get information about the classes such as Methods, Fields,Method References, Class References, Field References, SpongeMixin Info (Such as targets), Constants, and More! It is multithreaded and designed to make the full use of your computer and does not require  a JDK with tools.jar and can work on a JRE and is also much faster and more efficient than jdeps and provided information which jdeps does not. We use special vtuber technology to select the correct ASM target version with reflection so we can read modern classes.

Outside of the automated analysises, you can interact with the Finder with:

• Mods Tree
• Mixins Explorer
• Dependency Map
• More from Addons!

Each of these lets you easily find information which would otherwise be much harder to find without deep Java or computer knowledge.

Mods tree allowing you to see nested jars, classes, methods, fields, method references, field references,clas references,constants, Mixin Target information,and to search for these things and filter them for speed. Note that it will take a long time to load and be slow if you have too many mods but this can be used for finding which mods are touching which classes. It can also be used to find which mods contain which classes or packages, though if it is not a mod which a lot of other mods call it would likely be faster to use the grepr utility. If you have CFR Installed you can also decompile classes to see what they do more easily. With The Mods Tree, you can search with Hamu Energy!

Mixins Explorer is a tool with chiiaru which is similar to the mods tree but more specialised forwards SpongeMixins which are a common method of Bytecode injection used by many mods which are a common source of breakage, this tool lets you look through all the spongemixins and find their targets and find other spongemixins with similar targets to help find potentially conflicting ones. If you have CFR installed you can also decompile them as well. It also has an image of NMusic Telling CLAWZ to gomix, which was an inside joke in the CLAWZ discord, NMusic is a nightcorer, and CLAWZ is my favourite remixer who makes lots of HandsUp and Euro Dance remixes and originals. ChiiaruVTuber is also here to help cure all those mixups.

Dependency Map (DepMap) is a tool with NimuSpaceCat in the GUI for creating a visualised map of all your depencies so you can see what depends on what without needing to look in more traditional ways. There is another tab which shows in a list mode which has dropdowns, they are sorted by most to least dependent mods allowing you to find orphan dependencies. There is also a misaligned dependencies viewer which allows you to see which mods you have the wrong dependency versions for. This is common with mods like Create, EpicFight,AzureLib,GeckoLib,FeatureCreep,Catacylism,AllTheLeaks,IronSpellbooks and many more which have large addon ecosystems but change internals a lot every major version leading to a large % of the addons not working when the mods update. Just select the base mod and root package (will often be determained automatically,especially for common cases which we will hard code the packages for you to make it easier and more accurate) and it will search the addons and dependent mods for ones which are misaligned with the version you have now. You are able to decompile classes if you have cfr installed to see how important the issues are. I got the idea for the depmap from a kind vtuber from the MinecraftForge discord (NOT Nimu) who asked how to find which mods are not needed by any dependent mods. We based the idea on Big Rigs Over the Road Racing which emphesises going extremely fast through everything without crashing, because in CrashDetector You're Winner!

If you are a mod developer you can implement our interface com.asbestosstar.crashdetector.Extencion to include new errors related to your mod, tell it new logs to look for, add new buttons to the GUI, add log splitters and cleaners, add new pastebin APIs and sites, custom patches, and more. You do not need to know very much Spanish and most of the terms are similar to in English. Modpack creators may also use this functionality for their modpack, but if you want deeper changes it is recommended you fork CrashDetector. CrashDetector is not protected by intellectual property so you are free to fork it and make whatever changes you would like without even mentioning that your fork is in any way related.

If you do not want to compile a new java mod you can program in JSON by creating a file called firmas.json in the crash_detector folder. It can create basic analysis based on if a line or the full log has a string or regex. You can make custom crash reasons for your corperation or modpack. You do not need to know how to code we have a NoCode GUI which can write the code for you.

CRT Gaming

As the best Crash Analyser we optimise for the best display type. We make sure CrashDetector looks good on your CRT Monitor or TV. We also test on a High end Plasma Monitor and LCD monitors. (Note CRTs are hard to get good pictures of so it looks better in real life, like 1000x better than an OLED BVM)

PRIVACY NOTICE: IF YOU USE THE SHARE REPORT BUTTON. YOU ARE UPLOADING A COPY OF YOUR REPORT TO OUR SITE asbestosstar.egoism.jp/crash_detector/ AND KEPT THERE FOR 3 DAYS. THE LOGS ARE UPLOADED TO SECURELOGGER.NET FOR SOME TIME. IF YOU DO NOT WISH TO HAVE YOUR LOGS UPLOADED DO NOT USE THE SHARE BUTTON. THE REPORT CONTAINS THE FOLLOWING INFO:
LINKS TO YOUR LOGS
THE CONTENTS OF THE SCREEN IN THE MIDDLE OF OUR GUI

By default Crash Detector is set to anonymise your logs client side, this can be turned on or off in the config on the bottom of the share screen, it will remove sensitive info such as access tokens, UUIDs, usernames, and IPs before they are even uploaded to the log site. This is still in beta though so issues may exist.. You can also switch log sites here and report endpoints. You can also use a custom log site so long as it is supported by the API you selected by editing the config in the crash_detector folder.

If you got Crash Detector in a modpack be sure you look over these settings as modpack devs are able to change them.
