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…

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…

I built a second one and the client to talk to it.

Hey HN, I am proud to show you guys that I have built an open source alternative to Azure OpenAI services. Azure OpenAI services was born out of companies needing enhanced security and access control for using different GPT models. I want to build an OSS version of Azure OpenAI services that people could self host in their own infrastructure. "How can I track LLM spend per API key?" "Can I create a development OpenAI API key with limited access for Bob?" "Can I see my LLM spend breakdown by models and endpoints?" "Can I create 100 OpenAI API keys that my students could use in a classroom…
