Tabs, splits, and tmux work fine until you have several projects open with logs, tests, and long-running shells. I kept rebuilding context instead of resuming work. Horizon puts shells on an infinite canvas. You can arrange them into workspaces and reopen later with layout, scrollback, and history intact.Built in 3 days with Claude/Codex, dogfooding the workflow as I went. Feedback and contributions welcome.

Could you build this?
No Building a custom GPU-accelerated infinite-canvas terminal in Rust requires deep systems programming, PTY handling, and custom graphics pipeline development.
What it would actually take: The architecture demands a low-level graphics stack in Rust using WGPU or Vulkan, combined with text rasterization engines (like cosmic-text or freetype) and cross-platform pseudo-terminal (PTY) concurrency. The hard part is managing high-throughput ANSI/VT100 terminal parsing, viewport virtualization on an infinite 2D canvas, and memory-mapped scrollback persistence. This requires specialized systems engineering and graphics rendering proficiency.

20 comments analyzed.
Competitors mentioned: InfiniteGlass - general infinite canvas window manager, Terminator - terminal with splitting screens, tmux - terminal multiplexer, KDE default terminal, Alacritty - terminal emulator
Concerns raised: InfiniteGlass difficult to install even on supported systems, Terminator crashes frequently, Many tmux windows become unwieldy to manage, Terminal tab switching becomes cumbersome at scale, CPU usage concerns with certain features
Feature requests: Cross-platform support (Linux and Windows bridge), Shell session persistence across multiple windows, Infinite scrollable canvas with touchpad gestures, Better integration with file browser from terminal, Settings/minimap UI overlap fix
