PTY · 01
Local terminal
Spawns your default shell in any folder, rendered live as a texture inside the RealityKit scene. Outdoor build only — the App Store sandbox can’t fork your zsh.
A terminal that lives
in 3D space.
Catty renders your shell as a floating panel inside a real-time 3D scene. Local zshor SSH. There’s a cat in the room and a magenta wireframe rat orbiting your prompt.

Specifications
Built for shells in space.
Two distribution channels, four surface modes, three cameras — and a cat that watches all of it.
SSH · 02
Remote sessions
Pure-Swift SSH via Citadel — no system openssh required. Works on every build, including the sandboxed App Store one. Bring any host that accepts a shell.
UI · 03
Indoor & Outdoor
Outdoor: notarized DMG, Sparkle updates, Homebrew cask. Indoor: sandboxed Mac App Store build. One codebase, two entitlement files, one bundle ID.

A cat in the room
Maxwell-the-cat orbits the scene. He doesn’t judge your typos. The rat is a wireframe homage to Ratty (Orhun Parmaksız) — the project that inspired all of this.

Surface modes
Map your terminal onto a flat plane, an IMAX curve, a Möbius strip, or a centre-bulge CRT warp. Each pane has its own shape — mix and match.
CAM · 06
Three cameras
Orbit (turntable around the panel), ride-along on the rat, or mount Maxwell’s head and pirouette through the scene. Drag to look. Scroll to dolly.
