Sunviz 3D — know the light before you go

Interactive sun position visualizer. Drop any address into a photo-real 3D view with a sun compass on top. See the exact hours a building's front, a storefront window, or a backyard sits in direct sunlight on any date, which way its shadow falls, and how long that shadow runs — so you scout, shoot, and book viewings around the light instead of guessing on site.

Golden Hour Planner

A 2D planning tool for landscape photographers — find sunrise, sunset, golden hour and blue hour times for any location on a satellite map, with live sun direction and twilight phases. Unlike the Sunviz 3D tool above (which models shadows on a specific building facade), this planner forecasts the sun's path across the whole scene so you can scout the best light and direction for any outdoor shoot.
