Monaco Editor & Terminal

Full-featured offline editor and real PTY terminal, both running natively.

Monaco Editor#

The editor is powered by the same Monaco engine used in VS Code, loaded via a custom Electron protocol handler for fully offline operation. Zero CDN requests, zero network dependencies.

Features

• Multi-tab editing with drag-and-drop reordering
• Breadcrumb navigation to click through the file path
• Syntax highlighting for TypeScript, Rust, Python, JSON, TOML, and more
• Multi-cursor editing with Ctrl+D to select next, Ctrl+Shift+L to select all
• Minimap for code overview on the right side
• Find and replace with Ctrl+F for search, Ctrl+H for replace
• Code folding to collapse and expand code blocks
• Auto-indent for consistent code formatting

Offline-First

The Monaco editor runs through a custom protocol handler registered in Electron's main process. No network requests for the editor itself, no CDN dependencies, and your code never leaves your machine.

Terminal#

DAEMON's terminal is a real PTY implementation using node-pty and xterm.js, not a browser-based emulator.

Features

• Real PTY sessions with full shell access and proper signal handling
• Multiple tabs to open as many terminal sessions as you need
• Split panes to divide terminals horizontally or vertically
• Per-project sessions where each project gets its own terminal context
• Command history with Ctrl+R for reverse search
• Tab completion with standard shell tab completion
• Copy/paste using select to copy and right-click to paste
