SSPL is a source-available license originally created by MongoDB, who set out to craft a license that embodied the ideals of open source, allowing free and unrestricted use, modification, and redistribution, with the simple requirement that if you provide the product as a service to others, you must also publicly release any modifications as well as the source code of your management layers under SSPL.
