                  SkateSpots helps skateboarders discover spots, connect with pros at The Lab, and organize sessions -
                  all without corporate control. The real skating happens offline, this tool just connects you to it.

              Skateboarding knowledge should live with the community, not locked in corporate apps.
              That's why SkateSpots runs on Nostr - a relay-based system where skaters control their own
              data, choose which relays store it, and can even run their own. No single company owns the map.
