About
Heavy Inventories adds RPG-style carrying weight to Minecraft, making players weigh what to pack and leave room for loot on the way back. It counts equipped armor, offhand items, and nested container contents, including bundles and shulker boxes, against a carrying capacity; default material weights and recipe-derived weights give items their load values. As a load approaches or exceeds capacity, players can be slowed or stopped, and weight can also affect hunger, stamina, falling, swimming, sinking, flight, and knockback; server settings let operators tune these effects and choose gradual slowdown or a threshold-based mode. Strength potions and the Bracing chestplate and Reinforced leggings enchantments increase carrying capacity, while Surefooted boots help maintain movement when encumbered and Soaring elytra reduce weight penalties during flight. A weight ring behind the XP level, optional numeric readouts, and item and container tooltips show how much players carry and how it compares with their capacity. Server-side datapacks can override individual item weights, including weights for modded items, so modpack makers can adapt the system to their worlds.

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. 2 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
- 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.14 latest files: the newest file for each Minecraft version and loader. The answer above is about the 9 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.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
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 9 files, for recent Minecraft versions. See each file in Releases
- 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
AI was used to make it
The author declares AI content on Modrinth, without saying for what.
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.Declares AI content. No AI features declared.
