About
Easy Server Optimizer is a server-side mod that monitors performance and adjusts optimizations in real time, so only the server or multiplayer-world host needs to install it. As TPS falls, it scales view and simulation distances, applies stronger optimization rules, and can temporarily pause weather or the daylight cycle and freeze entities as emergency safeguards. It limits mobs per chunk and clears projectile buildup, while its villager optimizer can pause the pathfinding and brain processing of stationary villagers and restore their AI temporarily when a player interacts with them. For item cleanup, it adjusts lifespans by item type so selected drops such as cobblestone, dirt, or netherrack can despawn sooner without shortening the usual lifespan of valuable gear. When the server has been empty for at least five minutes, it can restore the game time to when the last player logged out, preventing time-based progression while nobody is playing. A built-in profiler can identify the most entity-heavy loaded chunks and the most numerous entity types, helping admins locate sources of lag. Automatic optimization is optional to manage manually through the /opt commands, and the server configuration supports custom lifespans for selected items.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Changes your mods folder
- It can add or replace files in your mods folder, for example to update itself. Only in its files for NeoForge 26.1 to 26.1.2; Forge 1.20.1.
- 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
- 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.7 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 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, 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
- 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 4 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 and images 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
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found4 of 40 changelogs read

- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found
