MPL-Using Projects

This page contains two lists - MPLed projects, and GPLed projects using MPLed libraries. You need an account to edit this wiki; if you can't be bothered to get one and want to add data, email Gerv.

MPLed Projects

This is a list of as many free software projects under the Mozilla Public License versions 1.0 or 1.1 as we can find.

Note that, for those projects whose License Steward is "Netscape Communications Corporation", the steward is now the Mozilla Foundation - Mozilla acquired these rights from Netscape when it was founded.

Only projects whose license steward is the Mozilla Foundation are directly relevant to the question of GPL compatibility in MPL 2, but we would like to make a list of all projects using MPL-like licenses, for completeness.

Compatibility Position

This column indicates whether the project, by action (such as dual licensing) or by (linked) mailing list discussion, has indicated a position on whether their code should be able to be used in LGPLed and GPLed projects. The options are: "in favour", "indifferent", "against" and "undecided".

Also supportive of compatibility are, or could be:

• the FreePascal community, who have regular license troubles because their compiler is GPL/LGPL and much open source Delphi code is MPLed (because Borland used MPL for Jedi). They have a document explaining their problems.
• The maintainer of curl, who originally used the MPL and relicensed to a permissive licence to get GPL compatibility.
• The developers of iText in 2009, who wanted to go from LGPL to MPL but had to retain a dual license to keep GPL compatibility. (They have since gone to AGPL-only for commercial reasons.)
• Bjørn Reese and Daniel Stenberg, who would have used the MPL for their projects if it was GPL-compatible.
• LGPLed projects which want to use FreeImage (or use some project which uses it, like OGRE). FreeImage is dual GPL/FIPL (an MPL derivative).
• The developers of Bitlbee, who had to rewrite their Jabber interface module because they are GPLed and it was MPLed.

Much of the above list came from Ohloh. But there are some projects Ohloh either incorrectly lists as being under the MPL, or which are dead and not worth looking into further. They are: Vimperator, DimDim, Mindquarry Collaboration Server, Columba, Cobian Backup, Mindquarry Desktop, openQRM, L2j-c3, OSHIP, Web9, jw-flv-player, Turbopower Async Professional.

GPLed projects using MPLed libraries

This is only legal with a GPL exception. However, projects without such an exception should still be added - the purpose of this list is not to go chasing people.
