Last releaseHow long ago the newest file came out, or an existing file was marked as working on a new Minecraft version.15 months ago (17 Jul 2025)Supports popular versionsWhether the project has a file for a Minecraft version that 15% or more of the popular mods updated in the last 6 months also support. A version many modpacks use, like 1.20.1 or 1.21.1, also counts after a release in the last 12 months.1.21.8 on Fabric and NeoForge, 1.20.4 on Forge. 15% of the 721 popular Fabric mods updated in the last 6 months also have files for 1.21.4.

About
UPNP for dedicated servers automatically forwards network ports for a dedicated Minecraft server when it starts and closes them when it stops, helping players host for friends without manually forwarding ports or using third-party hosting. You can configure which ports to forward, including TCP and UDP ports; TCP port 25565 is opened by default, and additional ports can be configured for services such as Simple Voice Chat or Geyser. The mod also provides a command that reports the mapped ports and the IP address players need to connect.

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. 3 files in your config folder.
- 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 1 web address. 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.9 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 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
Sends data we could not identify
Sent to 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.
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 4 files, for recent Minecraft versions. See each file in Releases
- 239.255.255.250Purpose not known.Nothing about you
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Purpose not known.Data we could not identify: the code sends something, but not a kind of data our checks can name
- 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 description, files and images and found none.
We have not read its changelogs and 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 found in the descriptionChangelogs not read yet
- 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 found
- 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 file10 code files read
