JChemPaint is computer software, a molecule editor and file viewer for chemical structures using 2D computer graphics.[1] It is free and open-source software, released under a GNU Lesser General Public License (LGPL). It is written in Java and so can run on the operating systems Windows, macOS, Linux, and Unix. There is a standalone application (editor), and two varieties of applet (editor and viewer) that can be integrated into web pages.
