    About

    Opis is a server profiling tool that helps administrators identify performance bottlenecks and inspect their sources. It measures timing for entities and tile entities, presents the results in categorized tabs, and lets users teleport to lag sources, with MapWriter support for displaying locations and quick navigation. Additional profiling views cover network packets and channels, ping round trips and processing, server and client events, and rendering time for entities and tile entities. Its other diagnostics include live counts of entities, tile entities, forced and loaded chunks, dimension information, and a tool for finding orphaned or duplicated tile entities.

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.6.4 to 1.7.10.

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

    What it can do on your computer

    Can download and run new code
    The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware. Only in its files for 1.7.2 to 1.7.10.Not a Warning: we read its code and found no code downloaded over http or run without a check.
    Accepts connections from other computers
    It can accept connections from other computers. Only in its files for 1.7.10.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for 1.7.2 to 1.7.10.
    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Only in its files for 1.7.10.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for 1.7.2 to 1.7.10. See Privacy
    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 1.7.2 to 1.7.10.

    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 3 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.
      3 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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.

    Privacy

    We found nothing it sends about you

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.6.4 to 1.7.10.

    We read its code without running it: it contacts 1 web address while you play.

    Like any connection, each address it contacts sees your IP address.

    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 Minecraft 1.6.4 to 1.7.10. See each file in Releases
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Connects to game servers or other players.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files and images and found none.

    We have not read its changelogs 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.
