Honua is a cloud-native, AI-ready geospatial platform for teams modernizing GIS infrastructure without a big-bang rewrite. Its flagship, honua-server, connects existing GIS clients and AI agents to the same PostGIS-backed data through GeoServices REST, OGC APIs, OData, STAC, tiles, gRPC, and MCP. Supported ArcGIS Pro and Esri SDK workflows connect without application rewrites, making migration and coexistence a first-class path. Import existing ArcGIS services into PostGIS, migrate GeoServer catalogs, and move supported workflows service by service.
