StackPatch
Patch authentication into your Next.js app with one command
StackPatch is a command‑line tool that adds production‑ready authentication to a Next.js project with a single command. It creates real files in the repository that provide Google and GitHub sign‑in, protected routes, and session handling. The solution is open source, requires no SaaS services, and avoids vendor lock‑in, making it suitable for developers who need secure authentication without external dependencies.
