Rune

Rune is a native, GPU-accelerated IDE and terminal multiplexer built for both manual programming and AI-assisted development. It combines code editing, terminals, language intelligence, debugging, workspaces, and agent workflows in one environment. Its interface supports nine workspace slots along with many terminals, tabs, and windows. Rune instances can form an end-to-end encrypted peer network so users can connect to one development machine from another. The editor includes production-grade language support and can be extended through official or community packages. Its graphics pipeline uses OpenGL on Linux and Metal on macOS instead of Electron. The bundled Rune Agent is shipped as an extension so AI coding remains separate from the core editor.
