About
Additive is a Fabric modpack that provides an open-source, modular alternative to OptiFine, combining rendering and game-logic optimizations with familiar visual and quality-of-life features. It includes built-in shader support through Iris, zoom, dynamic lighting, better grass, connected textures, custom item textures and entity models, capes, animated textures, custom colors and skies, emissive effects, and resource-pack controls for particles, details, animations, and other toggles. The pack also adds lightweight utilities beyond OptiFine, including controller support, borderless fullscreen, render-resolution adjustment, tooltip fixes, and a calculation command, alongside input fixes for Linux and macOS. Features are supplied by separate mods, so users can remove options they do not want or that conflict with other mods, and can add compatible mods of their own. Built in sync with the performance-focused Adrenaline pack, Additive aims to improve rendering, logic performance, memory use, and hardware efficiency while retaining Minecraft’s appearance and features. Its contents are open-source or source-available, and the pack is published in a form intended to be inspected, contributed to, or forked.

Security
No harmful code found in its projects
We checked all 56 projects and the files in the pack itself, without running them.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
How we checked
- Its projects56 projects
- Files in the pack itself17 settings files, no mod jars.
- 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.
Privacy
6 mods send something about you
We read the code of all 55 of its mods, without running it.
Why we show this: a modpack runs the code of its mods, and 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
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.4 mods
- Send nothingTheir code contacts no web address.45 mods
AI
AI used in 4 of the 55 mods we checked
We found an AI tool in them, or their authors declared AI content.
No sign so far that AI was used to make the pack itself
We looked for AI tools in its texts and found none.
We have not read its files, images and code history yet.
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 declared.
