Sigil is a free, open source, multi-platform ebook editor. It is designed to edit books in ePub format.


Issue Tracker

Issue tracking is intended for discussion around issues with the code. It is not intended for developers to discuss ideas before taking the time to implement them. It is also intended for actual bug tracking. It is not intended for feature requests.

At one point in time issue tracking was disabled because it had become unhelpful. The majority of issues where requests or abusive comments related to Sigil not running on older OS's whose own manufacturer had declared end of life.

Feature requests opened on the issue tracker will be closed if there isn't anyone willing to implement the requested feature. Only items being worked will be left open.

Build and Install

The file in the docs directory contains information on building Sigil from source code (and installing it on Linux machines).


Sigil is licensed under the GPLv3. The complete license is located in COPYING.txt.

Note that libraries and components Sigil used and bundles may use a different license (that is compatible with the GPLv3) from Sigil. See the specific component for their respective license.
