Tailscale is just a commercial service that builds upon wireguard. It automatically generates certificates for each of your devices, ensures they're rotated and up to date, automatically configures routing and DNS between your devices and offers some additional functionality.

Tailscale has open source clients but a proprietary server to do this, but you can use the open source alternative headscale instead: https://github.com/juanfont/headscale
