About
Geyser is a proxy that lets Minecraft: Bedrock Edition players join Minecraft: Java Edition servers, translating network traffic between the two editions to make cross-platform play possible. To bring Bedrock closer to the Java experience, it includes an integrated resource pack with features such as armor-stand poses, offhand animations, missing particles, illusioners, and interface adjustments for menus that differ between editions. Server owners can also provide Bedrock resource packs and configure mappings for custom items, blocks, skulls, waypoint icons, and entities; Geyser does not automatically convert Java resource packs or create these mappings. Because the editions differ, some features cannot be supported perfectly, and Geyser’s translation has known limitations.

Libraries packed inside it change 2 more game code files: Cloud and Cloud Command Framework.
Adds no new blocks, items or other content.
Keeps all of vanilla Minecraft's textures, models and sounds.

No harmful code found
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 Fabric 26.2 to 26.3; NeoForge 26.2 to 26.3; Paper 1.20.5 to 26.3; Velocity 1.21 to 1.21.4, 26.2 to 26.3; BungeeCord 1.21 to 1.21.4, 26.2 to 26.3.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. Found in code libraries built into it, in Java-WebSocket, a library it includes and in MinecraftAuth, a library it includes.
- Starts other programs
- It can start another program on your computer. It can read system or hardware information.
- 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, in code libraries built into it and in 8 libraries it includes. 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 Fabric 1.20 to 26.3; NeoForge 1.21 to 26.3.
- Uses your Minecraft account login
- It can use the login of your Minecraft account, for example to join a server. Only in its files for Fabric 1.21 to 1.21.8; NeoForge 1.21 to 1.21.8; Velocity 1.21 to 1.21.8; BungeeCord 1.21 to 1.21.8.Not a Warning: we read its code and found no login token sent anywhere but Mojang.
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.54 latest files: the newest file for each Minecraft version and loader. The answer above is about the 44 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.
- Accepts connections from other computersRuns a small web server.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, updating itself, the webcam or microphone, an AI service.

Sends usage statistics, crash reports and unknown data
Sent to api.mclo.gs, dump.geysermc.org and bstats.org.
We found this in its code, read without running it.
The author declares on Modrinth that it sends crash reports or usage data unless you turn this off.
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 44 files, for recent Minecraft versions. See each file in Releases

AI
AI was used for its code
Claude Code is named in its files.
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.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Nothing found
