Bespoke co-designed platform for agent-based or patch-based modeling of ecological processes with spatial data.

Presented at AGU25. Originally built for post-fire recovery modeling and policy.

Uses domain specific language which scales from in-browser (WASM) to local execution to distributed cloud all while including language features which make it easier to describe stochastic systems.
