About Tailscale

Tailscale creates a secure mesh network between your devices using WireGuard. You install the client on each machine, log in with your identity provider (Google, Microsoft, GitHub), and they can all see each other—even if they're behind NATs or firewalls.

What it does

Tailscale assigns each device a unique IP in a private network. Traffic is encrypted end-to-end with WireGuard. It uses a coordination server to exchange keys, but no traffic passes through Tailscale's servers—it's peer-to-peer. You can share specific devices with other Tailscale users.

Best for

Developers who need to SSH into servers or access internal services remotely
IT admins managing distributed teams with devices on different networks
Anyone who wants a simple VPN without configuring OpenVPN or IPsec

Free for up to 100 devices and 3 users
