Why

Most SaaS starters lock you into a single provider. LaunchFast exposes the slice that's the same everywhere - auth, payments, storage, email - and gets out of the way for anything provider-specific.

  • Built for every preference. Use your favourite stack for databases, authentication, payments and email - no lock-in.
  • Web-standards I/O. HTML-first components, native fetch, runs on Node, Bun, Workers and Vercel - anywhere your framework runs.
  • Out-of-the-box, not out-of-touch. Skip setup for databases, auth, payments, email, storage, docs and analytics - and still drop down to the native client when you need to.
  • Move faster, launch sooner. A proven starter built for production so you ship more and iterate quickly.

What's included

Each integration is pre-wired and swappable. Bring only what you use; the rest stays out of your bundle.

Authentication

Email/password, magic links, OAuth 2.0, password reset, email verification, protected routes, and admin access - all wired in and ready.

Hey, I'm Rishi.

Rishi Raj Jain @rishi_raj_jain_

I'm a software engineer and technical writer. I've worked with many clients, each with their own preferences - a specific database, their favourite auth method, a particular payment processor, a unique email provider. I kept finding myself rebuilding the same foundations with small differences every time.

That's why I built LaunchFast: a starter kit that supports all the popular providers for databases, auth, payments and email - so you can switch between them or pick what fits from day one.

  • Built for every preference. Use your favourite stack - no limits.
  • Everything works out-of-the-box. Skip setup for databases, auth, payments, email, storage, docs and analytics.
  • Move faster, launch sooner. Focus on your business and ship with a proven starter built for production.

Frequently asked questions

Got more questions? DM me on Twitter or send an email.

What do I get exactly?
1/ The Astro, SvelteKit or Next.js repo with all the starter code you need to run an online business: payments, database, login, UI components and more. 2/ Documentation that helps you set up your app from scratch, write copy that sells, and launch fast.
Why Astro?
Astro lets you write in any reactive library - Vue, React, Preact, Svelte - while still server-side rendering the app and keeping your SEO intact.
Why SvelteKit?
SvelteKit gives you the same HTML-first authoring experience with the reactive Svelte component model.
Why Next.js?
Next.js makes it super easy to ship React apps and takes the complexity out of routing, SSR, data fetching and middleware - with sane defaults that let you launch quickly.
I don't know Astro yet - can I still use it?
Yes. If you know HTML, React, Preact, Vue, Svelte or SolidJS - even mixed together - Astro supports it.
I don't know Next.js or React - can I use the Next.js kit?
Unfortunately, no. Even though the integrations are decoupled from the front-end, you'd still need a working knowledge of React to make use of the Next.js template.
Do you offer technical support?
Yes. I'm fast at resolving any queries related to the LaunchFast codebase - DM me or email anytime.
What payment methods are supported?
Lemon Squeezy supports more than just Stripe and PayPal - Apple Pay, Google Pay, Alipay, WeChat Pay, Cash App Pay and ACH are all available.
Can I use PayPal?
Yes. Send the USD equivalent to my PayPal, then email contact@launchfa.st with your GitHub username and I'll grant repo access within a few hours.
Is it just a website template?
No - it's a collection of standalone components and APIs built on top of the Web API. You can copy/paste sections (pricing, hero, FAQ), reuse buttons and other UI components, or pull endpoints from /api. Plus a killer SEO component written in bare HTML.
I can build it myself - why should I buy?
True. While you're building, others are launching.
Can I get a refund?
No - all products are digital.
