What Is LaunchKit? Next.js SaaS Starter Kit

What Is a SaaS Starter Kit?

A SaaS starter kit is a pre-built codebase that includes the common functionality every software-as-a-service product needs: authentication, subscription billing, user dashboards, and landing pages. Instead of spending weeks building these from scratch, developers can clone a starter kit and focus on their unique product features.

LaunchKit is a production-ready Next.js SaaS boilerplate designed specifically for developers and founders who want to ship fast without sacrificing code quality.

Why Choose LaunchKit Over Other Boilerplates?

The Next.js ecosystem has dozens of SaaS templates. What makes LaunchKit different is its focus on modern, maintainable architecture with zero vendor lock-in:

• Next.js 15 + React 19 — Latest features including Server Components and the App Router
• Supabase for auth and database — Open-source, generous free tier, easy to self-host
• Stripe for payments — Industry standard with webhooks pre-wired
• Built-in CRM — Capture and manage leads without third-party tools
• SEO-ready blog — MDX-powered content with structured data

Who Is LaunchKit For?

LaunchKit is built for three main audiences:

• Indie hackers and solopreneurs — Ship your MVP in a weekend, not a month
• Startup founders — Get to market faster with production-grade infrastructure
• Freelancers and agencies — Use as a starting point for client SaaS projects

How Long Does It Take to Launch?

Most developers go from clone to deployed product in under a day. The typical timeline looks like:

• 30 minutes — Clone, install dependencies, set up environment variables
• 1-2 hours — Customize branding, update copy, configure Stripe products
• 2-4 hours — Add your core product features
• 30 minutes — Deploy to Vercel or your preferred host

Compare that to 4-8 weeks of building auth, payments, and infrastructure from scratch.
