Heliora

Heliora is "Street View for the sun." Drop a pin anywhere on Earth and get a 3D sky view from that exact spot, showing the sun's and moon's path across the sky against the real terrain horizon — decoded from elevation data, not a flat skyline.

See exactly when a mountain ridge blocks the low sun, when golden hour actually begins at your location, and what a solar eclipse will look like from where you're standing — including a frame-by-frame replay of the 12 August 2026 total solar eclipse over northern Spain. Named peaks, hour markers along the sun's arc, stars and constellations, and shareable links that render the same moment in any timezone.

Free, runs entirely in the browser, no account or install needed.
