About
What is this?
StarWalls is a free web app for browsing and downloading NASA space photos as wallpapers. Photos come from three NASA sources: the Astronomy Picture of the Day (APOD), Image of the Day, and the current Artemis II mission archive.
How it works technically
Built on Next.js 16 App Router with ISR for fast first loads and Framer Motion for animations. A service worker enables offline browsing of previously loaded photos. There is no backend database — all data comes directly from NASA's public APIs.
Images
All photos are NASA imagery, in the public domain. The NASA name, logo, and images are trademarks and property of NASA.
