Horizon reimagines terminal management with a GPU-accelerated infinite canvas approach. Unlike tabbed or tiled terminals that constrain workflows, this open-source tool places every terminal session as a freely positionable panel. Created by peters, the solution emerged from frustration with rebuilding context instead of resuming work across multiple projects with logs, tests, and long-running shells. The tool offers pan, zoom, and minimap navigation across an infinite 2D workspace.

Built in just 3 days using Claude/Codex while dogfooding the workflow, Horizon offers full terminal emulation powered by Alacritty's engine. Users can organize terminals into color-coded workspaces with five layout modes or arrange freely. The tool integrates AI agents, provides git status panels, detects URLs and file paths, and maintains session persistence across sessions. A live settings editor allows instant configuration changes with YAML syntax highlighting.

With support for Linux, macOS, and Windows, Horizon represents a significant shift in how developers manage complex terminal workflows. The infinite canvas approach solves the context-switching problem that plagues developers working on multiple projects simultaneously, offering a visual workspace where terminals remain exactly as left when resumed. The project is available under MIT license with contribution guidelines available in the repository.
