A GPU-accelerated terminal board, Horizon provides an infinite canvas for organizing terminal sessions, AI agents, and development tools. It addresses the limitations of traditional tabbed or tiled interfaces by offering a spatial, zoomable workspace, enabling developers to visualize and manage complex workflows holistically.

How It Works

The project employs a GPU-accelerated rendering pipeline using wgpu to create a boundless 2D workspace. It integrates the high-performance alacritty_terminal engine for robust terminal emulation. Users organize sessions as resizable panels, freely positioning them or utilizing auto-arrangement layouts within color-coded workspaces, all navigable via an integrated minimap.

Quick Start & Requirements

• Installation: Pre-compiled binaries are available for Linux (x64), macOS (arm64/x64), and Windows, requiring only extraction and execution. Building from source involves cloning the repository, git lfs install, git lfs pull, and running cargo run --release.
• Prerequisites: Building from source requires Rust 1.88+ and Git LFS. Linux installations may need specific system headers for GPU rendering (see AGENTS.md).
• Links: Releases page (implied), AGENTS.md.

Highlighted Details

• Infinite Canvas: Pan and zoom across a limitless workspace with a navigational minimap.
• Workspaces: Group panels into color-coded workspaces with flexible auto-layout modes or free placement.
• AI Agent Integration: First-class support for Claude Code and Codex with persistent sessions.
• Built-in Git Status: Real-time panel displaying repo changes and diffs.
• Smart Detection: Interactive URLs and file paths via Ctrl+click.
• Remote Host Discovery: Fast overlay for SSH/Tailscale host management.
• Live Settings Editor: YAML configuration with instant preview and application.
• Session Persistence: Restores all workspace states upon restart.
• Markdown Editor: Split-view editor with live preview.
