Download Geany – Lightweight and Fast Source Code Editor and IDE

Geany is a lightweight, fast, and feature-rich source code editor that doubles as a basic Integrated Development Environment (IDE). Built on the GTK toolkit, it is available for Windows, Linux, and macOS, and is designed to load quickly and remain responsive even on older or low-powered hardware.

Despite its small footprint, Geany supports syntax highlighting for over 50 programming and markup languages including C, C++, Python, PHP, JavaScript, HTML, CSS, Java, Rust, and many more. It includes a built-in terminal, a symbol browser, code completion, auto-indentation, and a project manager — giving you most of what you need for daily coding without the heavy resource demands of a full IDE.

Geany is extensible through a rich plugin ecosystem, allowing you to add features like version control integration, snippet management, file tree browsing, and much more. It is the go-to editor for developers who want a fast, capable tool that stays out of the way.
