Gaea builds procedural 3D terrains through a node graph, and is used as a reference tool for landscape and environment work in games and VFX. Paid editions add tiled builds at very high resolution, Houdini support, and macro-based automation on top of the free, non-commercial Community edition.
The entry commercial license, Indie, costs 99 USD once, with no subscription, but is node-locked to two computers and excludes Houdini and macro creation. Freelancers and small studios under 1M USD in annual revenue fit the Indie or Professional editions; above that threshold, the more expensive Enterprise edition is required by the license terms.
Practical uses

Our verdict. What to know about Gaea.
How the score breaks down
Added value
4/5
A one-time 99 USD Indie license covers commercial terrain work indefinitely, with no recurring subscription, which is cheap relative to the category.
Simplicity
3/5
Neutral score: the time needed to produce a first usable terrain is not covered by the collected sources.
Fit for purpose
4/5
The tool is described as a standard for procedural terrain generation, with tiled builds at very high resolution confirmed on paid editions.
Performance
4/5
Support for tiled builds up to 262,144x262,144 and macro-based automation on the higher tiers point to a high capability ceiling in the category.
Reversibility
3/5
Neutral score: export formats and data portability out of Gaea are not covered by the collected sources.
