HISE is distributed under a dual-license model:
Open Source (GPL)
If you're releasing your project under the GPL license, it's free to use.
Commercial License
If you want or need to avoid the freedom and copyright implications of the GPL license, you can acquire a commercial HISE license. It is a company-wide license that allows you to release as many proprietary projects as you want as long as your license subscription is active.
The licensing fee for proprietary usage is a monthly fee determined by the yearly revenue that you've made with HISE based products and it is categorized into two subscription tiers (INDIE/PRO):
Starting with the release of HISE 5 there is also a new HISE Starter Pack that allows developers to start publishing with HISE to up to 2k € total revenue without a periodic commitment.
| STARTER | INDIE | PRO |
|---|---|---|
| below 2.000€ total revenue | below 50.000 € annual revenue | above 50.000 € annual revenue |
| 200€ one time payment | 50€ / month | 300€ / month |
| non-renewable | monthly subscription | monthly subscription |
Yearly payment options for the subscription licenses are available on request.
