SvelteKit SaaS starter with Email & Password
Ship Email & Password in your SvelteKit 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 Email & Password in SvelteKit means OAuth callbacks, session storage, CSRF edges, and protected routes that break the first time you deploy to production.
Building it yourself
Scaffold SvelteKit, find a Email & Password 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
- Email and password sign-up with hashed credentials
- Email verification and forgot-password flows included
- Works alongside Google, GitHub, and magic-link auth
How teams ship with this kit
- 1
Clone and configure
Add your Email & Password keys and provider settings to the included env template. The SvelteKit 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 SvelteKit app.
Also ships with every SvelteKit kit
- Stripe or Polar billing
- Magic-link email
- Protected admin routes
- Deploy configs
Common questions
Is this only about Email & Password?
No. The SvelteKit kit is a complete SaaS foundation. Email & Password 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 SvelteKit 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 Email & Password guides for Astro and SvelteKit too.
