Show HN: Bike route planner that follows almost only official bike trails

16 hours ago (trailimap.com)

Hey guys, I built a route planner that is mostly focused on bike touring and using existing bike infrastructure.

For each request you're shown what bike tracks/trails your route uses and can further explore them by showing them on map or going to the official trail route.

The main idea for the app is to have a friendly and easy to use planner that would make heavy use of official bike trails data (mainly from OpenStreetMap) and make it easy to plan a longer trip using the best possible bike routes out there.

Currently the app only works for the Euro region but I'm planning to add North America very soon and then rest of the world.

Technical overview: Route finding - Graphhopper sitting in a docker container on a Hetzner server somewhere in Germany. It has 38 GB of graph data(Europe) loaded into RAM for a fast graph traversal.

Web App - Next.js 14 with Typescript, backend on the newest version of .NET

Map tiles - right now I'm using MapTiler their free tier but planning to switch to my own home server soon and host the maps on it.
