RealSaaS is my take on the old Next.js Subscription Payments starter, which is now deprecated. I put in a lot of work improving the UI, refining the Supabase auth flow, and integrating Lemon Squeezy for payments and didn't want the code to go to waste.

I really like the auth flow they had of using params to trigger toasts. There are some issues that I think still need to be figured out with the whole middleware auth flow which I have personally found to cause perf issues like slow navigation. Open sourcing this hopefully lets people optimize this.
