Horizon – GPU-accelerated infinite-canvas terminal in Rust
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.
In plain words
Horizon is a GPU-accelerated terminal emulator built in Rust that organizes shells on an infinite canvas instead of traditional tabs and splits. Users can arrange multiple shells into workspaces and reopen them later with layouts, scrollback history, and command history preserved. Designed for developers managing multiple projects with concurrent logs, tests, and long-running processes, it solves the context-switching problem that conventional terminal multiplexers create. The tool was built rapidly and welcomes community feedback and contributions.
