# SvelteKit SaaS starter with Lemon Squeezy

Monetize your SvelteKit product with Lemon Squeezy 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 SvelteKit founders spend the first two weeks on Lemon Squeezy webhooks, checkout state, and entitlement checks before they write a single product feature.

Scaffold SvelteKit, find a Lemon Squeezy 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.

## Why LaunchFast

LaunchFast is a production SvelteKit repo where Lemon Squeezy already talks to auth, billing, and deployment. Add your keys, customize the UI, and ship while the cross-cutting SaaS plumbing stays done.

### Benefits

- Merchant-of-record friendly checkout
- Webhook handlers included
- Apple Pay and local payment methods via Lemon Squeezy

## How it works

### Clone and configure

Add your Lemon Squeezy keys and provider settings to the included env template. The SvelteKit app boots with the integration active.

### Customize product flows

Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.

### Deploy with included configs

Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.

### Swap providers later

Client wants a different payment processor or database? Change adapters through config instead of rewriting your SvelteKit app.

## FAQ

### Is this only about Lemon Squeezy?

No. The SvelteKit kit is a complete SaaS foundation. Lemon Squeezy 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 Lemon Squeezy guides for Astro and SvelteKit too.
