Sigil is an open-source editor for EPUB e-books developed by Strahinja Marković in 2009.[2]

As a cross-platform application, Sigil is distributed for the Microsoft Windows, Mac OS X and Linux platforms under the GNU GPL license. Sigil supports both WYSIWYG and code-based editing of EPUB files, as well as the import of HTML and plain text files.[3][4]

Maintainer John Schember announced the discontinuation of Sigil in February 2014, recommending calibre as an alternative.[5] In September 2014, he wrote that development was to continue at a slower pace.[6]
