About
Simple Update Checker notifies players and server operators when an update is available for a Modrinth modpack, with checks running on both clients and servers. On clients, update information appears beside the modpack name and version on the main menu, while servers report it in startup logs and to operators when they join. The mod checks periodically, with server reminders becoming less frequent over time if an update remains available, and also provides a command to trigger a manual check. Settings let users disable checking or individual notification locations, while modpack configuration identifies the Modrinth project and can control displayed names and versions, eligible release types, and version matching.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. It contacts 2 web addresses. 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
- 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.8 latest files: the newest file for each Minecraft version and loader. All 8 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
- 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.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends about you
We read its code without running it: it contacts 1 web address 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.
How we checked
- 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 all 8 files, for recent Minecraft versions. See each file in Releases
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Checks for a new version of the mod.
- 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 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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found8 of 9 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found1 image read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file44 code files read
