category sell licenses for professional use #9

Closed aberlin closed 8 years ago

aberlin commented 8 years ago

this is maybe a new category: sell licenses for professional use Pros whole code is freely available

cons probably a lot of scary unhandy legal stuff Osirix Redhat Owncloud Some on this list have this approach

kennethreitz commented 8 years ago

Dual license of GPL + Commercial (for $) is common.

nayafia commented 8 years ago

hmm. is this covered by the "open core" category, or can it be rolled in somehow? what do you think?

kennethreitz commented 8 years ago

@nayafia sometimes the commercial version is identical to the open source (GPL) version, however, without the GPL (which companies can't use if they're shipping the code due to its virality).

shaunagm commented 8 years ago

I don't believe Red Hat has dual licensed products? MySQL is dual licensed, though.

aberlin commented 8 years ago

I think it is not really covered by "open core" category because the whole code is free. It would be more a "Consulting & services" but without consulting and service. Also the "sell licenses " category is more divers because on the one hand side there is the dual licensing, but on the other hand there is professional licensing(for medicine or heavy machinery) which doesn't really fit as consulting or extra service because the project focus is still on the code. I think for the second case Osirix is still the best case study I find but there are probably a lot more cases where the user needs a label for legal reasons and can not really work professional with plain GPL.

I think it is distinct from open core and from consulting & services. Copyleft (GPL/LGPL) with an option for a closed-source license is a fairly common case as mentioned above. SQLite is also in this "sell optional license" category as a very interesting example: it's public domain, but users can pay $6000 for an explicit license - see https://www.sqlite.org/copyright.html
