Next.js SaaS starter with Stripe
Monetize your Next.js product with Stripe checkout, webhooks, and paid-route gating already connected. Configure keys and pricing UI, then start collecting revenue instead of debugging billing plumbing.
The problem
Most Next.js founders spend the first two weeks on Stripe webhooks, checkout state, and entitlement checks before they write a single product feature.
Building it yourself
Scaffold Next.js, find a Stripe tutorial, wire env vars, fix auth sessions, then repeat for billing and email. Most teams lose weeks before the stack deploys cleanly or handles real users.
What you get out of the box
- Subscription and one-time checkout flows
- Webhook handlers for paid access
- Pre-built billing UI components
How teams ship with this kit
- 1
Clone and configure
Add your Stripe keys and provider settings to the included env template. The Next.js app boots with the integration active.
- 2
Customize product flows
Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.
- 3
Deploy with included configs
Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.
- 4
Swap providers later
Client wants a different payment processor or database? Change adapters through config instead of rewriting your Next.js app.
Also ships with every Next.js kit
- Google OAuth login
- Protected routes
- Transactional email
- PostHog analytics
Common questions
Is this only about Stripe?
No. The Next.js kit is a complete SaaS foundation. Stripe ships alongside auth, billing, email, analytics, storage, and deployment so you are not assembling the stack from scattered tutorials.
Can I see it working before I buy?
Yes. The live demo runs the same Next.js starter with real auth and billing flows. Open the demo, click through signup and checkout, then compare with your timeline.
What if I need Astro or SvelteKit instead?
LaunchFast ships the same integration surface in all three frameworks. Related links on this page point to the Stripe guides for Astro and SvelteKit too.
