Cesium ion provides generous free API access to Google Photorealistic 3D Tiles for open source projects, allowing Window View to be free without requiring you to bring your own Google Maps API key.
Antigravity with Gemini 3 Pro and Claude Opus 4.6 helped me build a lot of Window View! Antigravity's good support for image input and Gemini's strong vision capabilities were super useful due to the visualization nature of this project.
