Rune

Rune is a native integrated development environment built for Unix-style workflows and command-line integration.

Rune is a native integrated development environment built for Unix-style terminal workflows and command-line interaction. It provides a command prompt for driving actions, a console for IDE management, and terminal tiles within a single set of key bindings. Each instance functions as a node in an end-to-end encrypted network, allowing remote access to workstations. The application uses native graphics pipelines, specifically Metal on macOS and OpenGL on Linux, to avoid Electron dependencies. It supports over 300 languages, with specific tiers for Go, Python, Rust, and Zig, including features like language server protocols, debugging, and toolchain management. The interface design focuses on a quiet, minimal aesthetic with 16 included color themes.
