Tinyworldmap

tinyworldmap is a world map for offline-first and low-bandwidth web apps. It is partially based on a small subset of OpenStreetMap data. Due to its small size (450kB gzipped, ~1 MB uncompressed), it can be permanently cached and displayed even when a website is offline. It can both be used as a fallback map when the regular map is unavailable and as a standalone base map.
