Patch authentication into your Next.js app with one command
StackPatch is a CLI that patches production-ready authentication into Next.js projects. Run one command and get Google & GitHub auth, protected routes, and session handling all as real files inside your repo. -No SaaS -No lock-in -Fully open source.
Hey Product Hunt 👋
What inspired me to build StackPatch was pure repetition.
Every time I started a new Next.js project, authentication wasn’t hard, it was just the same setup over and over again: NextAuth config, routes, providers, protected pages, environment variables.
I didn’t want another hosted service or abstraction. I wanted a way to drop production-ready auth directly into my codebase and fully own it.
That’s how StackPatch started.
My approach evolved from trying to “simplify auth” to something more honest: patching real, editable files into the project using a CLI. No magic, no runtime dependency just code you can read, modify, or delete.
For this launch, I focused on keeping the scope tight:
one command, clear output, and a demo that shows exactly what gets added.
I’d love feedback from the community:
• Does this solve a real pain for you?
• What would you want to patch next?
Happy to answer any questions 🙂
