Features

Made for two displays.

01

Side by side

Two sessions share the inner display. Swipe the carousel to bring in another one. Let a session span both columns when it needs the room.

02

Outer display

Folded shut, the outer display runs one full terminal. Swipe to switch sessions.

03

Laptop posture

Fold it halfway and stand it up. The terminal moves to the top half and the keyboard sits below.

04

Key bar

Esc, ctrl, tab, arrows and symbols, in the order you set. The bar splits along with the split keyboard.

05

Keys and passwords

Sign in with a password or an SSH key. Ed25519 and RSA keys work, with or without a passphrase. Keys are stored in the iOS Keychain.

06

Host keys

duotty saves each server’s host key on first connect and checks it on every connection after that.

07

Inline images

Kitty graphics and Sixel images draw right in the terminal.

08

Nerd Font

Ships with the 0xProto Nerd Font, so prompts and file icons render as intended.

09

Snippets

Save the commands you type often. Send one with a tap.

10

Reconnect

When iOS drops a connection, the session offers to reconnect right where it is.
