Show HN: A small web app where people appear on a world map
I've moved around a lot. Finding information is easy. Finding people is weirdly hard.
So I made this — a map where you drop a pin and see who else is around.
Filter by digital nomads, freelancers, remote workers, retirees. See if they just arrived or have been there for years.
Spot someone interesting? Send a message.
No signup. No feed. No tracking. No algorithm. Just a map.
More like exploring than scrolling.
Built with Next.js, Supabase, and Leaflet.
- frankhsu 9mo agoThis is so COOL! I Just left a pin on the map!
- yoan9224 9mo agoCool concept! I built something similar (real-time visitor locations on a globe) and have a few thoughts: 1. How are you handling connection scaling? Realtime presence with many concurrent users gets expensive fast. We cap concurrent WebSocket connections and batch updates every few seconds rather than streaming every event. 2. The pin clustering looks good - are you using a quadtree or just distance-based clustering? At higher zoom levels the overlap can get chaotic. 3. One thing that worked well for us: showing a brief "trail" or fade-out when someone leaves, rather than just disappearing. Makes it feel more alive. What's your stack? The latency feels snappy.
