The Default License: GNU GPL
TightVNC is available under the terms of the GNU General Public License
(usually referred to as GPL). This is the primary type of licensing, you do not have to
pay for it or enter into any special agreement. Just download the software and use it for any
legally allowed purposes, including commercial use. Also, you may redistribute verbatim
copies of the software with no limitations (unless such distribution is restricted by local
or international laws). You even may modify the software and distribute its modified copies,
provided that all your modifications are GPL-licensed as well.
GPL Restrictions
While GPL is usually a good option for end users of the software, it may not be that good for
commercial software developers. GPL does not allow you to link GPL-licensed components
with your proprietary software (without publishing it under the GPL as well). Also, it does not allow you to modify the GPL code and make the changes proprietary. Thus, you cannot
use GPL code in your non-GPL projects (unless the GPL code is properly separated).
Business-Friendly Licensing
To solve the described problems, we offer alternate business-friendly licensing options for
certain parts of TightVNC. If you wish to integrate TightVNC into your commercial
software package and GPL is not an acceptable option, you should obtain a commercial
license. We can re-license only those parts of the software for which we own the complete
copyrights.
Currently, we sell licenses for the following completed products:
