Visifire has been using dual licensing scheme since it was launched.
- Open Source License under GPL 3.0
- Commercial License for companies which are considering Visifire for their non-GPL applications.
Initially we had not made the commercial licensing options public and we were responding to individual queries. But due to the volume of requests that we started receiving, we felt the need to make it public so that the companies and individuals who are considering Visifire for their non-GPL applications can know the commercial licensing options quickly.
You can get more information in the license page.
Thanks for your attention,
