What's free, and what's paid?

What’s free

dotMux is free to use, fully featured, for one saved host — tmux and herdr, SSH keys, the Secure Enclave, Face ID lock, iPad multi-window, all of it. Editing or re-pointing that one host stays free too.

Unlimited Hosts — $1.99, once

To save a second host and beyond, there’s a single one-time purchase of US $1.99 (“dotMux — Unlimited Hosts”). It’s a non-consumable purchase and not a subscription — no recurring charge, ever. Once you buy it, every additional host is unlimited.

The paywall appears only when you add a second host; you can also unlock any time from Settings.
