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.
SimpleX does not have required user identities at all (not even random user identifiers) and all users data - profiles, messages, contacts, groups - are only stored on user client devices. That makes your metadata - who you talk to and when - not visible to network or the servers, unlike any other design. Linked overview probably provides the best explanation on the design objectives and technical details.
SimpleX v1 has big changes in E2E encryption (now with double-ratchet), protocol encoding (overhead in transmitted bytes is reduced from 15% to 3.7%), performance and invitation link size (no more long RSA keys in URLs, we switched to Curve448/25519 keys). See more details in our v1 announcement.
I found this to be an interesting read about Matrix. https://github.com/libremonde-org/paper-research-privacy-matrix.org/blob/master/part2/README.md
