About
LoTAS is a Minecraft mod for making low-optimization, non-playback tool-assisted speedrun videos: players slow the game, perform a route, then record and edit the footage rather than saving inputs for automatic replay. Its core tools include a tickrate changer and tick-by-tick advancement for precise timing, plus savestates that let you back up and restore a world while testing a run. For RNG and route control, the mod can manipulate mob and block drops, steer the Ender Dragon between phases or toward a perch, spawn entities at selected valid locations, and direct entities along chosen paths. It also provides item duplication that reproduces vanilla duplication behavior without requiring a game restart, along with an in-game timer and an auto-clicker useful for bridging. LoTAS is intended for solo experimentation and video capture, not multiplayer or playback-based runs.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Accepts connections from other computers
- It can accept connections from other computers.
- 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 2 web addresses. 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
- 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 one for a recent version. 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

Sends your player ID
Sent to minecrafttas.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
- 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 its one file, for recent Minecraft versions. See each file in Releases

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 description, files and images and found none.
We have not read its changelogs and 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
- 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.
