Business Source License

The Business Source License (SPDX id BUSL[1]) is a software license which publishes source code but limits the right to use the software to certain classes of users. The BUSL is not an open-source license,[1] but it is source-available license that also mandates an eventual transition to an open-source license. This characteristic has been described as a compromise between traditional proprietary licenses and open source.[2]

The originator of the BUSL is MariaDB Corporation Ab, where it is used for the MaxScale product, not for the flagship MariaDB.[3]
