I may be missing something but this looks like an open source project vs. Auth0 which, while it has a free plan, is part of Okta and is a commercial product.
Maybe a better comparison point would be Keycloak. I’d also like to know how it compares to it.
I tried and it seems it's Keycloak with an easy UX, a lot less features, and you're limited to only one realm.
We started as for customer identity, which means the current version is for the apps that have external customers, e.g. an online store. We’ll constantly iterate to fit more scenarios.
In case you're looking for multi-tenancy with self-service, maybe try out https://github.com/zitadel/zitadel
Would be glad to get your thoughts on the platform.
(discl: I work for ZITADEL.
So Logto is an open source project you host yourself?
It's a open source library you integrate into your application.
It doesn't look like it's a library. It's a service you run. They also provide SDKs for app integration but that's not the same as being a library.
