    I’m Rishabh and the co-founder and CTO at https://supertokens.com (YC S20). We offer open-source user authentication and we just released our user roles product for companies implementing authorization. Our users are web developers, and a prominent and adjacent pain point for our users is authorization. Developers typically implement two independent solutions for authentication and authorization.

    Hi everyone, We’re building an open-source identity and risk management platform and we’ve just released the first chunk of code, a fully customizable KYC flow & UI, to the public. We’ve chosen to use Svelte so our flows would be lightweight (it is ~50kb gzipped). Next up: - Adding forms and components for it to be used as a full onboarding flow. - Releasing an open-source case management dashboard, for manual approval of users. - Releasing an open-source rule engine, to help automate decisions. We’d love to hear your feedback, suggestions, or any question you’ve got. And if the rest of the…

    Hey HN! Happy to finally launch Stack. We made it because we like to put apps into production quickly, and authentication & user management was taking up way too much time. We have components like and that automatically adapt to whatever theme & design system you're using. Check the blog post to see the example with Radix UI and Joy UI. Also, there's an admin dashboard for monitoring and editing accounts. Stack is 100% AGPL/MIT-licensed, so you can self-host it. Cheers!
