    About

    Simple Blood adds pixel-art blood effects to Minecraft as a client-side visual mod, so its effects run on your computer rather than requiring the server to have the mod. Hits spray blood away from the wound toward the attacker, with distinct effects such as sword streaks, axe splashes, mace craters and arrows punching through. Blood splats onto block surfaces, spreads, runs down walls and around edges, pools below, drips from structures, and gradually dries into a darker, eroding film. It can leave footprints from entities that walk through fresh blood, while landing sounds and squelching footsteps add audio feedback; rain washes blood away, and water disperses it into a fading cloud. Blood appearance varies by mob: slimes bleed green, endermen purple, and skeletons crumble into bone dust, with additional particle kinds including liquid, debris, ember and powder. The settings provide live previews, presets and controls for blood amount, particle limits, and per-mob colour and effect type, including modded mobs. Players can choose a blood colour and share it through their Minecraft skin so other players using Simple Blood can see it, including on servers without the mod installed. With Physics Mod, ragdolls continue bleeding and leave a splat where they land.

    Security

    No harmful code found

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

    What it can do on your computer

    Uses your Minecraft account login
    It can use the login of your Minecraft account, for example to join a server. Only in its files for Fabric 26.1 to 26.3; NeoForge 1.21.1 to 26.3.Not a Warning: we read its code and found no login token sent anywhere but Mojang.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. It contacts 1 web address. See Privacy
    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 · All 16 latest files checked, last on 22 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.
      16 latest files: the newest file for each Minecraft version and loader. All 16 are 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.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    Sends unknown data

    Sent to api.minecraftservices.com.

    We found this in its code, read without running it.

    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 16 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.

    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
      Nothing about you
    • 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 for its code

    The author declares AI code on Modrinth.

    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.
