In the self-hosted space, I've been really enjoying playing around with decentralized encrypted overlay mesh networks like Nebula. Here's the current list of my faves (all Wireguard based). Open-source projects not-quite-prod-ready: - WebMesh: Golang, decentralized nodes https://github.com/webmeshproj - InnerNet: Rust, with subnet ACLs https://github.com/tonarino/innernet - Wesher: Golang, simple mesh with pre-shared key https://github.com/costela/wesher - Wiresmith: Rust, auto-configs clients into a mesh https://github.com/svenstaro/wiresmith Open source projects with company-backed SaaS offerings: - Netbird: Golang, full-fledged solution (desktop clients, DNS, SSO, STUN/TURN, etc) https://github.com/netbirdio/netbird - Netmaker: Golang, full-fledge solution https://github.com/gravitl/netmaker Honorable mention: - SuperHighway84

From a purely networking perspective, there are far better solutions than tailscale. Have a look at full mesh VPNs like: https://github.com/cjdelisle/cjdns https://github.com/yggdrasil-network/yggdrasil-go https://github.com/gsliepen/tinc https://github.com/costela/wesher These build actual mesh networks where every node is equal and can serve as a router for other nodes to resolve difficult network topologies (where some nodes might not be connected to the internet, but do have connections to other nodes with an internet connection — I work with networks like that every day). Sending data through multiple routers is also possible. They also deal with nodes disappearing and change routes accordingly. tailscale (and similar solutions like netbird) still use a bunch of "proxy servers" for that. You can set them up on intermediate nodes, but

A quick search for overlay mesh network wireguard resulted in https://github.com/costela/wesher. Anyone experience with wesher or the like?

For WireGuard there's the official https://github.com/WireGuard/wg-dynamic, or also this: https://github.com/costela/wesher. Or generally for mesh networks as others mentioned: Slack's Nebula, ZeroTier (wait for v2) or Tailscale.
