WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
Helping the community. There is a gigantic database called EDDN that gets data from many different sources to build the tools you've seen above and much more. It's a phenomenal community-based enterprise, and one of the reasons why I've fallen in love with this game (despite the Black Adders). Wanna contribute? The link above will guide you through. Basically download, install and configure one of the recommended apps and all necessary information will be sent to the database, for everyone to use.
