Horizon is a GPU-accelerated terminal board that puts all your sessions
on an infinite canvas. Organize, pan, zoom, and never lose a terminal again.
Tabbed terminals hide your work. Tiled terminals box you in. Horizon gives you a canvas — an infinite 2D surface where every terminal lives as a panel you can place, resize, and group however you want.
Think of it as a whiteboard for your terminal sessions. Keep your frontend, backend, logs, and AI agents all visible at once — across multiple color-coded workspaces — and navigate between them with a minimap.
|
Pan and zoom freely across a boundless workspace surface. Place terminals anywhere. A minimap in the corner keeps you oriented — click it to jump. |
Group related panels into color-coded workspaces. Auto-arrange with five layout modes — rows, columns, grid, stack, cascade — or drag panels freely. |
|
24-bit color, mouse reporting, scrollback, alt-screen, and Kitty keyboard protocol. Powered by the Alacritty terminal engine — the same one behind the fastest terminal on the planet. |
First-class Claude Code and Codex integration. Sessions persist and auto-resume. A live usage dashboard tracks token spend across agents. |
|
A built-in git status panel watches your repo in the background. See changed files, inline diffs, and hunk-level detail — no context switching. |
Ctrl+click a URL to open it. Hover a file path and click to jump to it. Horizon sees what your terminal prints and makes it interactive. |
|
Open the config with Ctrl+, — a side panel with YAML syntax highlighting and live preview. Every change applies instantly to the canvas behind it. |
Close Horizon, come back tomorrow. Your workspaces, panel positions, scroll positions, and terminal history are restored exactly as you left them. |
