jEdit

jEdit is a Java‑based programmer’s text editor that runs on macOS, Windows, Unix and other platforms. It provides syntax highlighting and auto‑indentation for over two hundred languages, supports many character encodings including UTF‑8 and Unicode, and offers code folding and word‑wrap features. The editor is highly configurable, with a built‑in macro language and an extensible plugin architecture that lets users add functionality directly from a built‑in plugin manager.

The core application and its extensive collection of plugins are maintained by a global community of developers and distributed under the GPL 2.0 license, giving users full access to the source code. jEdit’s plugin ecosystem includes hundreds of macros and extensions, enabling customization to suit a wide range of development workflows.

Designed for programmers, jEdit aims to combine the capabilities of larger commercial IDEs with the simplicity of a lightweight editor, while remaining free and open source. Its stability and long‑standing development history make it suitable for developers seeking a configurable, cross‑platform editing environment.
