There are two options for using BlastEm in a commercial project. '''Commercial Use of BlastEm under GPLv3'''[[BR]] BlastEm is licensed under GPLv3 which allows commercial use without payment, but comes with certain restrictions. This is the preferred option for licensing. '''Proprietary Licensing'''[[BR]] If the GPL is a problem for your use case, it's possible to pay for a proprietary license.
