I built a SaaS starter kit that runs on a $5 VPS because I got tired of the "Vercel Tax"

Most SaaS boilerplates today have a hidden flaw: They lock you into a stack of expensive managed services.

Most SaaS boilerplates lock you into expensive managed services (Vercel, Supabase). Before you get your first customer, you are burning $50+/month. The Boring SaaS Starter Kit is different.
