JJazzLab FAQ
- Is JJazzLab free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use JJazzLab?
- You install it like a normal desktop app. No command line involved.
- Does JJazzLab work on a phone?
- No. It needs a computer.
- Can I use JJazzLab commercially?
- The licence is LGPL-2.1. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
