ZeroTier
Peer-to-peer virtual networking
Coldcast Lens
ZeroTier creates virtual networks that make your devices think they're on the same LAN, no matter where they are. Peer-to-peer, encrypted, and works through NATs and firewalls without port forwarding. Think VPN but without the VPN server bottleneck.
If you need to connect home servers, cloud VMs, and your laptop into one flat network, ZeroTier does it with one command per device. Tailscale is the slicker alternative — better UI, easier ACLs, built on WireGuard. Nebula (from Slack) is lighter but requires more manual setup. Traditional VPNs like WireGuard work but need a central server.
Best for homelab enthusiasts and indie hackers who self-host services across multiple locations. The free tier covers 25 devices — plenty for personal use.
The catch: the control plane is hosted by ZeroTier Inc. by default. You can self-host it, but it's more work than Tailscale's Headscale equivalent. Performance is slightly behind WireGuard in raw throughput. And the licensing is a custom BSL-style — check it if you're embedding it in a product.
