Blender add-ons can grow trees, but no free tool pairs procedural vegetation with wind animation, LODs and game engine export.

What a free alternative needs
The capabilities that keep people paying for SpeedTree.
1
Procedural trunk, branch and leaf generators
Hand-editable generators for many species, with art-directed control over shape and variation.
2
Wind animation baked for engines
3
Automatic LODs and billboards
4
Engine and DCC export presets
5
Seasonal and species asset library
Why it is hard
Wind animation data and LOD pipelines have to match each engine's vegetation shaders, and a useful species library needs many hours of botanical modeling.
Closest free options
Each covers part of the job. None replaces SpeedTree yet.
Partial: Geometry nodes and tree-generator add-ons build meshes; wind data, LODs and engine export are manual work.

List your tool on Gratistack when it works. Once an editor maps it to SpeedTree, it shows on this page and in search, and the people waiting here can hear about it.
Listing is free. An editor reviews the free queue every week.
Want a decision sooner? The optional $49 fast-track gets one within 48 hours. It buys speed, not approval, and a rejection is refunded.
Once it is listed as an alternative, you can sponsor the alternatives page for $149 per 30 days. Sponsors are labeled and never change the ranking.
