PrimeTimber - Just a better Timber mod!
by primeapi
PrimeTimber, a Fabric mod for 1.21.10, changes how a whole tree is felled when a player breaks one of its logs with an axe.
What it does
Holding the trigger key, which defaults to Left Shift, while looking at a tree stem with an axe shows an outline around the tree before any block is cut. Green means the axe has enough durability to break the whole tree from a single block; red means it does not. Visual indicators also show how many blocks would be felled before the cut is made.
The mod uses an improved tree detection algorithm, which the author describes as more accurate timber selection, so the outline follows the tree that will actually come down. It is labeled as an advanced take on the Timber idea, and either side can run it, while neither a server nor a player needs it.
PrimeTimber is published only for Fabric, with a single version, 1.21.10, and its latest file is 1.0.0 for 1.21.10, dated 2025-11-23. The code is open source under the CC0 1.0 Universal license, which places it in the public domain. Source code and an issue tracker are linked from the project.
Key features
Felling preview outline
Holding the trigger key while looking at a tree stem outlines the tree before any block is broken.
Durability color cue
The outline turns green when the axe can fell the whole tree from one block, and red when its durability is too low.
Felled block count
Indicators show how many blocks would come down before the tree is cut, so the scope is clear in advance.
Improved tree detection
A revised detection algorithm aims for more accurate selection of the blocks that belong to the tree.

Use cases
Clearing trees with an axe
Players who fell trees often can check the outline and its color before chopping, to avoid breaking an axe mid-tree.
Who it’s for: Players on Fabric 1.21.10 who fell trees often and want to see the felling area before cutting. Server owners can run it, though it is optional on either side.
