Detailed comparison table

Aspect	NetBird	Tailscale	ZeroTier
Purpose	Mesh VPN with granular access control	Mesh VPN with SSO, simplicity-first	Flexible L2/L3 virtual networks
Installation	Official script, netbird client	Official script, tailscaled service	Official script, zerotier-one service
Dashboard	app.netbird.io or self-hosted	admin.tailscale.com (SaaS)	my.zerotier.com or your own controller
Routes and LAN	Access policies, advertised routes	--advertise-routes + approval	Managed routes per network
ACLs/Policies	Policies by group/peer	Centralized JSON ACLs	Network-level Flow Rules
DNS	Per-peer/network DNS in the dashboard	MagicDNS and nameservers	Per-network DNS assignment
Self-hosted	Yes (control plane and TURN)	Limited (Headscale as an alternative)	Yes (controller)
Typical scenarios	Secure access between sites/servers	Access between devices/teams	L2/L3 overlays, labs
