This looks very refreshing! Congrats for officially launching,I think StackAuth was mentioned here before.

What are your plans for supporting "old school" frameworks, like django, rails, bootstrap, et al?

I know that it makes sense to target greenfield projects first, and I presume most new projects are started with some new cool tech (if looking at npm downloads or some other vanity metric or online questionnaire), but I think there's a long tail of users of other tech that would potentially provide high quality feedback based on real world experience at various settings.

I'm only saying this as it looks like you want to own the whole auth stack, all the layers and all the workflows, from dba to sales so to speak.
