About
OptiFabric is a Fabric-based alternative to OptiFine, bringing shader support, resource-pack compatibility, and rendering and background optimizations intended to improve performance and reduce memory use. Its OptiFine-like features include zoom, dynamic lights, smart leaves, capes, advanced video settings, and HD screenshots, while visibility culling skips blocks and entities the player cannot see and server-list pinging is optimized. Resource packs can use animated and connected textures, custom GUIs and items, custom skies, HD fonts, random entities, custom entity models and colors, splash screens, and anisotropic filtering. The listed included mods and tools include Iris Shaders, MoreCulling, Lithium, EMF, ETF, Mod Menu, and Reese’s Sodium Options; Zoomify and Language Reload are also listed as returned components.

Security
No harmful code found in its mods
We checked all 36 mods 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 projects36 mods
- Files in the pack itself1 settings file, no mod jars.
Privacy
4 mods send something about you
We read the code of all 36 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.2 mods
- Send nothingTheir code contacts no web address.30 mods
AI
AI used in 3 of the 36 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 and images 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.Not on Modrinth.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found2 of 40 changelogs read
