MySQL software is Open Source

MySQL software is Open Source.
Open Source means that it is possible for anyone to use and modify the software. Anybody can
download the MySQL software from the Internet and use it without paying anything. If you wish, you
may study the source code and change it to suit your needs. The MySQL software uses the GPL
(GNU General Public License), http://www.fsf.org/licenses/, to define what you may and may not do
with the software in different situations. If you feel uncomfortable with the GPL or need to embed
MySQL code into a commercial application, you can buy a commercially licensed version from us.
See the MySQL Licensing Overview for more information (http://www.mysql.com/company/legal/
licensing/).
