About this project

What does Component Viewer add?

🗒️ Description

Component Viewer is a mod for Minecraft Java Edition that allows you to view and copy components of any item stack. This mod is configurable out of the box by pressing J. If tooltips become extensively large, you can use a mod like Tooltip Scroll or just copy the data to a separate text file. Fabric API is required when using Fabric or Quilt.

I'm running a survey to better understand how people are using this mod. I want to collect ideas to improve this mod based on your feedback. I takes a few minutes and I would appreciate it: Google Form (last updated: July 26, 2026)

Thank you! :D
