Free Excelsior JET Licenses
We gladly provide Excelsior JET licenses at no cost to authors of free, non-commercial Java applications that meet the qualification criteria below.
To determine whether your project qualifies, answer this question first:
Is your project non-commercial in nature?
Your project must not directly or indirectly support any commercial efforts. For details, see the FAQ section below.
If you have answered "No", check out the Charity Bundles.
Further qualification depends on which Excelsior JET Edition you want to license (refer to the Feature Matrix for comparison):
Free Standard Edition licenses are unavailable for the duration of our 2013 charity campaign.
Your project must have a publicly available Web site that meets the basic quality standards, and the binaries must be available for anyone to download.
You must link back to the Excelsior JET home page from a prominent location on your project's Web site - home page, download page, etc. Usage of our official badges is encouraged but not mandatory.
In turn, we write about interesting projects in our blog, which can be an extra benefit for you.
Same requirements as for the Professional Edition above plus a write-up or co-marketing effort. Depending on your project, this can be a case study, performance/usability report, joint press-release, etc.
Important: Your write-up and/or co-marketing effort must be coordinated with and endorsed by Excelsior beforehand. Please contact us before committing to any such activity.
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.
Frequently Asked Questions
- 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 projects are welcome 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 Sun Microsystems 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?
- 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...
- 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 results of your project will be used in the business context, in other words, to help your employer, customer, partner, etc., make or save money, then a commercial license is required.
