About

What is Seasalt?

Seasalt is a remote access application designed for developers and technical users who need to securely control their Mac from an iPhone. It provides full terminal sessions, remote desktop capabilities, and a file browser, all protected by AES-256-GCM end-to-end encryption. A key differentiator is its zero-configuration setup, eliminating the need for complex VPNs, port forwarding, or static IPs. Both Mac and iPhone connect outbound to an encrypted relay, with keys exchanged directly between devices during pairing, ensuring the relay never sees user data. Seasalt is ideal for monitoring long-running processes, managing servers, or accessing files on the go, offering persistent terminal sessions and saved scroll positions.
