    About

    Satin API is a Fabric library that helps modders create graphical effects by simplifying the use of Minecraft’s data-driven post-processing shader system. Its managed shader effects can be initialized on demand, reloaded when resources or screen resolution change, and supplied with uniforms from mod code, making it easier to build effects such as a grayscale screen filter. The library also provides shader-loading and matrix utilities, rendering callbacks, and ways to apply custom shader programs or framebuffer targets to entities and block entities. Satin additionally patches shader handling to support mod-specific resource domains and custom post-processing target formats, while remaining a library rather than adding gameplay content or replacing OptiFine.

    Written from Modrinth and the GitHub README . How we write it

    In-game changes

    Changes the game's code in 3 areas, as a library other mods build on: Rendering and graphicsChanges 7 game code files in this area: drawing mobs, items, particles and textures on screen., World renderingChanges 1 game code file in this area: drawing the terrain, sky, clouds and weather. and Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses..

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    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 · All 14 latest files checked, last on 16 Oct 2026
    • 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 3 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 · All 3 files read
    • 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 3 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

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and code history and found none.

    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 · 6 places read

    Speed of updatesHow fast it gets a file for new Minecraft versions, on average, compared with similar projects. Not part of the grade.It has no file for Minecraft versions newer than 1.21.4. Many recently updated mods still support 1.21.4.

    Known conflicts

    These projects do not work together with Satin API: their authors or Satin API's author say so. If you install both, the game can crash or some features can stop working. Some of them do the same job as Satin API, so you only need one.
