About
OptiPack is a quality-of-life and optimization modpack that brings OptiFine-like visual features to a lightweight Fabric-based setup, originally assembled for friends and expanded to smooth out common base-game frustrations. For performance, it combines tools such as Sodium and Lithium for rendering and game logic with C2ME for chunk performance, Starlight for lighting, Krypton for networking, and Dynamic FPS for reduced background load. Visual options include Iris support for OptiFine-compatible shaders, connected textures, improved grass and snow, dynamic lights, and customizable block-entity appearances through resource packs. Quality-of-life additions include a customizable HUD, zoom, freecam for viewing or photographing builds, death tracking, quick crafting from the recipe book, controller support, and extra tooltip information. The pack also includes useful saved hotbars and tools for inspecting blocks, entities, and their data.

Security
No harmful code found in its mods
We checked all 31 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 projects31 mods
- Files in the pack itself12 settings files, 2 other 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
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.24 mods
AI
AI used in 2 of the 31 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 description and found none.
We have not read its changelogs, 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.
