The models' case: Delivers the lowest-friction onboarding for unmanaged contractor hardware by offering a completely clientless, browser-based reverse proxy for web apps, browser-rendered. The models' main caveat: Ineffective for contractors needing direct, clientless access to raw TCP/UDP, thick client-server apps, or legacy fat software without installing the. The strongest alternative is Twingate — Cleanest least-privilege VPN replacement for mixed resources (web, SSH, RDP, databases) without exposing inbound ports. Not unanimous: Claude picks Tailscale.
