Next.js SaaS starter with Google OAuth
Ship Google OAuth in your Next.js app with sessions, protected routes, and email auth working together. Skip the callback wiring, cookie edge cases, and deploy surprises that stall most OAuth rollouts.
The problem
Rolling your own Google OAuth in Next.js means OAuth callbacks, session storage, CSRF edges, and protected routes that break the first time you deploy to production.
Building it yourself
Scaffold Next.js, find a Google OAuth 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
- Server-side Google sign-in
- Session cookies and protected routes
- Email/password and magic links alongside OAuth
How teams ship with this kit
- 1
Clone and configure
Add your Google OAuth 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
- Stripe or Polar billing
- Magic-link email
- Protected admin routes
- Deploy configs
Common questions
Is this only about Google OAuth?
No. The Next.js kit is a complete SaaS foundation. Google OAuth 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 Google OAuth guides for Astro and SvelteKit too.
