Hi folks,

I am working on an open source project. I'd like it to be open-sourced, and FREE for personal usage, but charges for commercial.

Are there such licenses available?

Thanks in advance!

You could Dual license it under the GPL and your own proprietary commercial license. That of course wouldnt prevent someone from selling your script (along with the source), or using your script in-house (not to be distributed).

Canglan,

We've developed our own dual license that accomplishes what you're trying to do. You can use it if you like, as long as you refer to it by its full name, the Think Electronic License for Open Software (TELOS), and including the copyright notice.

As far as I can tell (since I am not a lawyer and I do not offer legal advice/opinion), Think Electronic License for Open Software (http://www.thinkcomputer.com/corporate/legal/licenses.html) (TELOS) does not comply with the Open Source Definition (http://www.opensource.org/docs/definition.php) (OSD), and so is not (and will not be) approved by the Open Source Initiative (http://www.opensource.org) (OSI), at least in its current form.

That said, it just means that software licensed under TELOS will not be OSI certified open source software. There is nothing stopping you from using TELOS, except that if you make such a choice, you should not (from a moral standpoint) claim that your software is open source software.

I agree with innova. There is nothing stopping you from offering your product under dual licenses. A lot of companies do this (such as RedHat, MySQL, etc.)

Generally though, the product that is licensed for commerical use includes something -- such as printed documentation, support services, certification, different media (such as CDROMs) etc.

I think you could use the GPL to release it, I think there is not need to reinvent licences as there are a lot of issues you might ignore. I attended a Richard Stallman conference and that was his advice, visit http://www.gnu.org/licenses/license-list.html
