PortPortveil vs Tailscale + Mullvad exit nodes
Both can send your traffic out through another country. They're built for different jobs. Tailscale is a private network between your own devices, and Mullvad exit nodes are an add-on for leaving the internet elsewhere. Portveil is a VPN whose exits you steer from code, built so AI agents' machines can be moved and checked remotely.

Choose Tailscale + Mullvad if
- You mainly want your own devices to reach each other privately, with single sign-on and access rules for a team.
- You need many exit countries.
- You already run Tailscale and just want an exit elsewhere now and then.
Choose Portveil if
- AI agents or scripts need to move a machine to another country and know it really happened.
- You want one dashboard showing which phones, laptops and agent machines are actually protected, confirmed by the exit.
- You want locations to rotate on a schedule without anything of yours staying online.
- You'd rather give an agent a limited token than your account.
