gpxsnap

Map tiles are fetched directly from tile.openstreetmap.org— no proxy, no backend.

A dependency-free GPX route-preview renderer — no sharp, no libvips, no native bindings anywhere in the chain. The same library behind the demo above runs in Bun, Node (≥22.18), and Deno too.

A real ~1200-point GPS track rendered near Lyon, France, hugging real roads — A real recorded ride, rendered by gpxsnap — dense GPS data already hugs the road network with a plain polyline stroke, no map-matching required.
