Free Excelsior JET Licenses

Authors of free, non-commercial Java applications can obtain Excelsior JET licenses at no cost.

To qualify, your project must not directly or indirectly support any commercial efforts.

You can begin the qualification process by answering this simple question:

Is your project non-commercial in nature?

Yes No Not Sure

Further qualification criteria depend on which Excelsior JET Edition you want to license (compare editions):

* Usage of our official badges is encouraged but not mandatory.

Your write-up and/or co-marketing effort has to be coordinated with and endorsed by Excelsior beforehand. Please contact us before committing to any such activity.

x We reserve the right to reject any otherwise qualified project at our sole discretion, as well as the right to approve any project that is not fully qualified. Email us if in doubt.
Does my project have to be open-source?
Not at all. Authors of free closed-source software are welcome to apply for sponsorship, whereas commercial open-source vendors need to purchase a commercial license.
Do open-source projects qualify automatically?
No. For instance, many commercial companies finance open-source projects in order to generate revenue. They can surely afford a commercial Excelsior JET license if they decide it would add value.
Is the Excelsior JET license GPL-compatible?

Unfortunately, no. Excelsior JET includes the Java SE API source code licensed from Oracle under SCSL Commercial Use license, which is not GPL-compatible. So even releasing our own code under the GPL won't help. LGPL is fine however.

We suggest you to release the natively compiled binary under a different license, pointing out that the source code is available under the GPL. You would however need the consent of all contributors.

Is accepting donations considered non-commercial?
Yes, provided that donors do not receive any benefits such as feature unlock or ads removal in return.
I use third party ads to support my project. Can I qualify for a free license?

It depends on the amount of revenue generated from those ads, though we admit it is difficult to draw the line. We'd say that a project is non-commercial if the revenues generated from ads do not go into authors' pockets, but are spent on the project - hosting, equipment, etc., or donated to charity.

Then, we do not like adware, but a reasonable amount of relevant advertisement on the project's Web site is OK.

What about the shareware authors? My product is yet to break even...
Many authors have found that offering a natively compiled version of their application increases both the number of downloads and the conversion rate. However, we understand that the upfront cost is way too high for a typical shareware author, so please check out our Microbusiness Licensing Program.
My product has a free version and a paid version. Can I still qualify?
See the previous answer.
Do internal projects (i.e. those never released to the general public) qualify?
Yes, they may qualify, provided that your organization is non-profit and secular. Otherwise, if the resulting software will be used in the business context, in other words, will help your employer, customer, partner, etc., make or save money, then a commercial license is required.
