24 alternatives to Authduck – Playground Server for OpenID Connect Clients
Hey HN I'm currently living my dream, being paid to do what I love: programming, something I've been doing since middle school for over 15 years. In those years doing programming, I’ve always thought that OpenID Connect/OAuth for Authentication is an amazing idea that more programmers should be familiar with. Using (properly configured) SSO may be one of the best security investment made by companies. It also saves a lot of works, both for companies (by delegating user management-related features to third party) and users (by reducing friction when using new services). However, one of…

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!

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. Offering AuthN and AuthZ in a single solution is something we’ve been thinking about for the last few years. Quick primer, authentication is knowing who the user is, and authorization is…

Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

Hi, I'm currently working as a dev on the BoxyHQ team, providing an OSS platform for devs to quickly plug-n-play enterprise features into their products. Jackson is one of our core offerings which enables SSO integration for your SaaS apps. We had support for SAML Identity Providers from day one. Today, I am excited to share that we now support OpenID Connect Providers also. With this change, we hope to cover almost all the SSO use cases out there. It would be great to get your feedback, please reach out to me at [email protected] Read more about it in our blog post:…

I, like Andrej Karpathy, became super frustrated by how annoying it was to deploy projects that were previously an absolute joy to make with Claude Code. That is why I made open-passkey, an MIT licensed passkey repo with support for 33 languages and frameworks (examples included) that makes adding simple secure auth to a project easy. We are also releasing gateway (https://gateway.locke.id) a "backendless" hosted auth server that frontend apps can consume for free so that you can ship a React or Angular app using a CDN like Netlify without needing to configure a server at all. We…

over this weekend myself and two of my friends took part in a hackathon and built this side-project. we have been diving into computer-use recently and developed an sdk to make it easy to implement for devs like us. one feature we were missing though, was the agent being able to log into services. anthropic understandably blocks this capability with their guardrails, and you wouldn't want your credentials to end up in any model context anyways. so we added a keychain service to the vm that the agent is using. it was built using the pass cli (https://www.passwordstore.org/).…
