    About

    ViaForge is a client-side ViaVersion implementation for Minecraft Forge and NeoForge that lets supported clients connect to servers running a wide range of protocol versions. Its server compatibility spans modern releases as well as Beta, Alpha, and Classic versions, including Classic with CPE, plus the 3D Shareware April Fools version and Combat Test 8c snapshots. The mod can also send a custom payload with a player's protocol version so servers can use that information for anti-cheat checks or version-dependent logic, though compatibility with individual servers and anti-cheat plugins is not guaranteed.

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

    In-game changes

    Changes the game's code in 2 areas: User interfaceChanges 8 game code files in this area: menus, screens, tooltips, the chat window and the in-game overlay. and Networking and multiplayerChanges 6 game code files in this area: connections, the server list and what is sent between your game and a server..

    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.

    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. It can read the login token of your Minecraft account and use the login to join a server.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. Found in the mod's own code and in code libraries built into it. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file 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 20 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.
      20 latest files: the newest file for each Minecraft version and loader. The answer above is about the 8 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.
    • Uses your Minecraft account login
      Uses your account login to join a server.
    • 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, and uses your Minecraft login

    Sent to dump.viaversion.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 8 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.

      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

    No sign so far that AI was used to make it

    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.

    How we checked · 5 places read
