Oh wow, that's amazing - thank you! I really appreciate your offer and I love RWGPS. I just read your comment about about all the hardware you're using at RWGPS and it's clear you're operating on a completely different scale than I am :D Right now, I'm just running Graphhopper on a €40/month Hetzner server and free tiers on Vercel and Maptiler. Though I already hit the free-tier limits for Maptiler so I'm quickly setting up a Martin server to server Europe mbtiles on some cheap server instead. Once the traffic drops after this HN post I think a low-cost server should do the trick for now.

As for Graphhopper, I ran into some challenges during the Europe-wide import stage. It turns out 64GB of RAM wasn’t enough, so I ended up spinning up a 128GB instance on AWS. After tweaking some config settings and following the deployment guide, I finally got it working. I also had to change the source code a bit to link each "official bike route" edge to its corresponding OSM relation info but I managed to get it working in the end(using KVStorage and KValues).

For now, my planner is pretty basic, so I don’t want to bombard you with beginner-level questions. But if something more complex comes up down the road, I’ll definitely take you up on your offer to reach out. Thanks again—I really appreciate your help and generosity!
