Tailcat

Tailcat connects machines over an encrypted connection, even when they’re on different networks. No accounts, login flow, tailnets, or IP addresses. Just share a tailcat address and connect.

Setting up a tailnet makes sense when you need governable access, identity, and policy. Sometimes you don’t. You might need to SSH into a development environment for an hour. Give an agent access to a test machine for one task. Connect a game session. Move a file between two machines. Tailcat gives you a secure connection without requiring either side to become part of a larger network.

1. Listen: Run Tailcat on the machine you want to reach. It generates an address you can share to make a secure connection from other machines.
2. Share: Securely send the address to the person, machine, or agent you want to connect.
3. Connect: Use the address from another machine to connect securely. Tailcat makes a direct connection whenever possible, and can fall back to a tailcat relay if needed.
