The peer-to-peer, one-time alternative to Termius.
Matadoor is an iPhone and iPad app that drives the terminal and the command-line coding agents on your Mac over one end-to-end encrypted peer-to-peer QUIC link. It is a one-time-purchase alternative to subscription SSH clients like Termius that needs no exposed SSH server, no synced credentials, and no account.

Termius alternative, answered.
Matadoor · on-deviceFor controlling your own Mac, yes. Instead of running an SSH client that connects to a server you expose to the network, Matadoor pairs your iPhone or iPad with a menu-bar host on your Mac over an end-to-end encrypted peer-to-peer QUIC link.
No. You scan a QR code to pair and approve the phone on your Mac, which sets up an end-to-end encrypted link to the macOS host. There's no inbound port to forward and no SSH daemon to expose.
No. Matadoor is a one-time $19.99 app and the macOS host is free. Termius is freemium with its Pro and Teams features behind a recurring subscription.
Yes. Matadoor starts the four supported command-line coding agents when they are installed on your Mac, streams their output, and puts Approve and Deny under the question an agent is waiting on. It also opens a plain PTY terminal. It's built to run your Mac, not to be a general multi-host SSH manager.
Keep your work on your Mac.
