I am trying to do a feasibility study for doing a plugin that implements a 2D geometry solver in various programs. The solver is GPL v3. Some of the programs are GPL themselves but some are not, like Illustrator.

So if:

  • My plugin is distributed online, not as a part of a commercial application
  • My source is also distributed online, and complies with GPL Licencing
  • But you can not actually run said plugin without the commercial application as its a plugin for it.

Is this ok?

You cannot use the GNU GPL in a plugin for a non-GPL program.

However, you can use the GNU LGPL license.

  • What does that mean? The GNU LGPL will work.
