    About

    NiftyBlocks expands building and decorating with dyed planks, bricks, and concrete; checkered tiles, vinyl siding, and stucco; limestone, marble, and slate block sets; and more than 100 lighting blocks, from wooden lamps and glow lamps to fluorescent fixtures and street lights. For city builds, it adds more than 400 traffic and street signs, including speed limits and highway shields, writable street and digital signs, over 200 asphalt blocks for road markings, traffic lights, cones, safety poles, and more than 800 lettering blocks in 16 colors. A Road Tool can build roads, while more than 100 vehicles range from cars, trucks, minivans, and motorbikes to taxis, emergency vehicles, forklifts, golf carts, and go-karts; players can drive them with a car key and bring a passenger. The mod also supports industrial production: players smelt alloys, crush ore, press plates, refine biofuel, and move goods on conveyor belts, powering equipment with coal generators, solar panels, or wind turbines and storing energy in batteries wired across a base. Storage options include sea cans and shelves, while hydroponic grow lights, a Terminal monitor, and the in-game Nifty Book support farming, monitoring, and learning the mod’s systems. New resources include aluminum, tin, bronze, steel, and rare earths, with hammer and cutter tools for making plates and wire, as well as bronze and steel armor. NiftyBlocks adds 33 foods, including pizza, doughnuts, bacon, baked beans, fries, and ice cream, along with wild blueberry bushes and aloe vera, maple, red oak, and rubber trees, and underground deposits of sulfur and other new materials. Its additions also include lawn flamingos, decorations, and the distinctive Nifty Block, giving players options for both whimsical details and larger creative or survival builds.

    Security

    No harmful code found

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

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for NeoForge 1.21.1; Forge 1.20.1.

    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 sounds 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
