A GUI terminal multiplexer for developers, built on libghostty (Ghostty's embeddable terminal core) with a Swift application layer.
quertty organizes work around pinnable projects/directories, each holding multiple terminal sessions with tabs and splits — and it natively detects AI coding agents (Claude Code, Codex, opencode, Aider, Gemini, hermes) running in those sessions, surfacing their status (running / idle / needs-attention) in the sidebar.
Platforms: macOS first; Linux later.
We build the multiplexer shell, not the terminal. Full libghostty provides VT emulation, GPU rendering, font/text shaping, surfaces, and both Kitty protocols (keyboard + graphics) for free.
Early design / pre-implementation. See the PRD for the roadmap.
