Ghosteel Terminal

Ghosteel terminal emulator for Sailfish OS

v1.0.0

Ghosteel brings a modern terminal engine to SailfishOS. Most mobile terminals use legacy VT parsers that struggle with complex TUI apps. Ghosteel uses the same engine that powers Ghostty, giving you accurate rendering for tmux, neovim, htop, and other TUI applications.

Features

Ghostty VT engine — full escape sequence support, 24-bit truecolor
GPU rendering — OpenGL ES 2.0/3.0 with cursor trail shaders
Multi-session — named sessions, switching, and persistence
Command sessions — launch TUI apps from desktop shortcuts (ghosteel -e htop)
Touch text selection — Sailfish-style magnifier, double/triple tap
Pinch-to-zoom — per-session font size adjustment
Extra keys bar — sticky Ctrl/Alt, arrow keys, F1–F12
URL detection — automatic hyperlinks, tap to open in the browser
Inline images — Kitty Graphics Protocol with PNG decoding
Encrypted scrollback — Encryption backed by Sailfish Secrets
Color schemes — Dark and Light with adjustable opacity
