Show HN: VeloPlanner – A cycling route planner focusing on official routes (opens in new tab)

For those interested in the technical implementation: I built VeloPlanner with my favorite tech stack: Elixir/Phoenix, React, and MapLibre GL JS. The architecture is a hybrid approach:

- Phoenix controllers for static content (route guides, listings)

- Phoenix LiveView for most of the forms

- React for the planner and interactive maps where high performance is critical

One of the bigger technical challenges was self-hosting all the infrastructure - I'm running my own map tile server and routing engine (Graphhopper) on beefy servers with lots of RAM to maintain full control over the cycling-specific routing algorithms. The memory requirements are substantial, especially for processing large-scale route data across multiple regions.

This approach lets me customize the routing to prioritize official cycling routes while still giving users flexibility when planning custom segments.

Happy to dive deeper into any specific aspect if there's interest!

This looks great, I've considered building something similar myself many times but won't have to anymore!

I like to stick to quiet backroads and nothing currently on the market does a good job of hinting at what will be a quiet/less traveled road.

Good luck!

Cool stuff! What's your current focus on, and what are your plans for the near future?

And congrats on the jump. It takes courage to go solo :)

Very cool and looks great. Good luck going forward!
