MongoDB dropped the #AGPL in late-2018 in favor of the "Server Side Public License" (SSPL), a modified version which requires those who offer the licensed software as a service accessible to third-parties, to make the entire source code of all software used to facilitate the service (including without limitation all "management software, user interfaces, application program interfaces, automation software, monitoring software, backup software, storage software and hosting software, all such that a user could run an instance of the service using the Service Source Code you make available") available under the same license
