Zoomburg
Zoomburg is a Fabric client mod that replaces fixed spyglass zoom with a configurable zoom key and scroll-wheel zoom.
What it does
Zoom is bound to a single key, C by default, and the key can be changed through the Controls screen under Options and Keybinds. Holding the key narrows the field of view, and the scroll wheel adjusts the zoom level while the key is held. A settings screen lets the player set the zoom field of view in real time and switch scroll-to-zoom on or off with a checkbox, and those choices are stored in a config file.
The mod works in survival, building and exploration, and in player-versus-player fights where seeing distant targets matters. It changes only the client view, so it adds no items, blocks or recipes and does not alter what the server does. Zoomburg is published for Fabric alone, with 8 game versions 1.21 – 1.21.8 and the latest file for 1.21.8 released on 2025-07-30. It is client-side only, so servers need nothing installed. It is released under the MIT License and is not open source. The mod is built with Fabric Loom, and its issue tracker is public.
Key features
One-key zoom
Pressing the zoom key narrows the view at once, and releasing it returns the field of view to normal.
Scroll-wheel zoom levels
The scroll wheel steps the zoom level while zoom is active, and it can be turned off in the settings.
Adjustable keybind
The zoom key is listed in Options and Keybinds, so it can be moved to any other key.
Settings screen
A simple screen sets the zoom field of view and the scroll-to-zoom option, saved in a config file.

Use cases
Distant views
Players who build, explore or film scenes can look at far terrain or structures without the size of a spyglass.
Combat at range
In PvP, zoom lets a player pick out a distant opponent or check the distance before shooting.
Who it’s for: Players who want zoom without switching to a spyglass or installing OptiFine, and players who want to tune the zoom amount themselves.
How it compares
Simple Zoom is Fabric and client-side only for 1.21.4 and is not open source, under All rights reserved. Zoomyy is also Fabric and client-side only, but its files are for 1.21.11 and it is not open source either. Zoomburg covers 1.21 – 1.21.8 under the MIT License and is not open source, so the two differ in version range and license.
