Environments for
simulation and training.

Metaplanets builds explorable environments grounded in places from Earth. The core engine is USRA — Star Matrix's whole-Earth synthetic reality architecture.

Proven today

Developers and world builders already explore full-scale synthetic planets on Metaplanets — in engine, on real hardware.

The focus

Simulation and training teams who need geographic context — built on USRA with Star Matrix. See the engine ↗

The open door

Studios and infrastructure builders can ship their own products on the same engine Project Earth and Creator run on.

Treated as modelling, not decoration.
