I built a fishing forecast platform for the Balkans on a 2× Raspberry Pi K3s cluster Hey r/selfhosted, Sharing a side project I've been running on my homelab for a while now — fishingbalkan.com — a free fishing forecast platform covering rivers in Serbia, Bosnia, Croatia, Montenegro, and the wider Western Balkans. I'm a DevSecOps engineer, not a fisherman, but built this for friends and family who fish.
