Ask HN: I need a license for an open source project allowing commercial reuse

[ivankirigin]

Tipjoy made http://tatatweet.com

You can get the source here: http://bit.ly/git_tatatweet

I'd like to fill up the license file with something more than:

  todo: insert business friendly license here :)

I'd like others to be able to copy the code and make money off of it. Any pointers?

An actual license file I can copy and paste would be helpful.

[ivankirigin]

I chose Apache. Thanks folks: http://github.com/ikirigin/tatatweet/blob/f310b2db75cfe0d507...

I'm not aware of any OSS license that doesn't allow others to copy the code and make money off it. even AGPLv3 (arguably the most restrictive license) allows it.

[j_baker]

The problem is that the AGPL and GPL require you to let anyone who buys your software fork it or give it away for free. This is how CentOS is made.

And if you use a GPL or AGPL library, you have to license the whole software package as such.

[JeremyBanks]

The MIT license (http://en.wikipedia.org/wiki/MIT_License ) and similar ones are pretty common choices. They more or less allow anything as long as attribution is provided.

[asb]

As a consumer of open source libraries, my vote has to go for MIT. There's nothing wrong with Apache but I really appreciate the brevity of MIT and BSD licenses. I know brevity isn't all you should care about, but both licenses seem to have stood up fairly well over the years while being intuitive to understand. I'm no fan of custom licenses, even if their meaning seems crystal clear (like the WTFPL). Sure it's funny, but I'd rather have people using my code be able to use it with complete confidence and with minimal hassle from their legal department.

APACHE / BSD / MIT

A lot of work went into the Apache license, and it's definitely business friendly, allowing for reuse in proprietary projects. BSD and MIT are a bit simpler more straightforward. The two things that are nice about the Apache license are the contributors clause and the patent clause.

[graemep]

The old BSD license is not compatible with the GPL - I assume that if you are allowing proprietary re-use, you would also want to allow as much open source re-sure as possible.

MPL is my personal favorite. Basically says you can use and modify the code in a whole bunch of ways, but if you release a version with changes you have to post the diff somewhere.

[Janzert]

I really do like the simplicity, brevity, and complete freedom of use of the MIT license.

Just replace <year> and <copyright holders> as appropriate.

[oomkiller]

You could go with BSD, it seems to be the standard for allowing other people to take your source and distribute it in a closed source product.

also, can do like SQLite and just make it Public Domain.

[xenoterracide]

This was more of a pain for SQLite than it was worth. It requires a lot more paperwork than just giving it a BSD (or similar) license.

[j_baker]

If you make it public domain, aren't you still liable (in the legal sense) for bugs or other issues?
