Logto's focus is on enterprises, while ours is on the developer experience for startups and side projects. I've used this line in a few comments on this thread already but I'd say that Stack is to Logto what Clerk is to Auth0.

(For Logto specifically, I'm actually surprised by what they consider "enterprise" features — something like OIDC, 2FA or RBAC should not be gated behind a paywall, IMO.)
