Stack, an open-source Clerk/Firebase Auth alternative▲144
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!

Support.dev – a non-trivial Vue and Supabase app▲55
I built this tool about a year ago to get really good at the supabase ecosystem. We were trying to raise money on the idea, but that didn't occur, so I wanted to open-source it, as I would love to give back to the commmunity. It allows you to invite friends and family to be helpers for child-care, meals, and transportation, and then you can create an event and they will get auto-invited to it and can choose to support you. It is using vue on the frontend and then supabase on the backend for auth, database, realtime, storage, and edge functions. Anyway, I hope someone finds it useful, there…

Bknd – Firebase alternative that embeds into any React stack▲50
I built bknd because I was tired of stitching together auth, file storage, and database APIs every time I started a new project. Existing solutions were either too hard to extend, too basic, or required a separate deployment. bknd runs directly inside your frontend app — no separate backend required. It works with Next.js, Remix, Astro, React Router. It also runs standalone on Cloudflare Workers, AWS Lambda, Bun, or Node. It supports Postgres, LibSQL (Turso), D1, SQLite and has adapter-based storage. You get instant APIs, multi-strategy auth, media handling and a built-in Admin UI. Curious…
