How I Built a Complete SaaS in 3 Days Using My Own Boilerplate

Every time I start a new SaaS project, I waste 2-3 weeks rebuilding the same infrastructure: Authentication (GitHub, Google, email/password) Payment processing (subscriptions, webhooks, billing portal) Dashboard (sidebar navigation, stat cards, settings) Database schema (users, plans, billing) Deployment configuration So I built ShipKit — a production-ready SaaS starter kit that lets you skip straight to building your product. What's Inside ShipKit is a complete Next.js 14 codebase with everything a SaaS needs: Authentication (3 providers, zero config) // GitHub, Google, and Email/Password — all wired up // Just add your API keys to .env.local GITHUB_CLIENT_ID=your_id GOOGLE_CLIENT_ID=your_id NextAuth.js handles the heavy lifting. JWT sessions, provider callbacks, account linking — it's all there.
