Astro · Next.js · SvelteKit

Launch your SaaS without rebuilding auth, payments, and infra from scratch.

Every new project starts the same way: wire up login, billing, email, and deploy, and lose a week before you write product code. LaunchFast gives you all of it pre-integrated with the providers you already use. Pick your framework, clone the repo, ship.

Why LaunchFast

Tired of ripping out Stripe because a client wants Lemon Squeezy? Or swapping Postgres for Supabase halfway through a build? Most starter kits pick your stack for you. LaunchFast wires the boring parts: auth flows, payment webhooks, email templates, file uploads. Then lets you swap providers without rewriting your app.

  • No provider lock-in. Use Stripe or Polar, Postgres or MongoDB, Resend or Postmark. Change your mind later without a rewrite.
  • Runs where you deploy. HTML-first components, native fetch, and configs for Node, Bun, Cloudflare Workers, and Vercel.
  • Production-ready, not prototype-ready. Auth, billing, email, storage, docs, and analytics ship wired. You customize what matters.
  • Ship this week, not next month. 110+ developers already run LaunchFast in production. Clone, configure, launch.

Cheaper and faster than prompting it

You can ask Cursor or Claude to scaffold a SaaS. The bill and the calendar still add up fast. LaunchFast is battle-tested plumbing you clone once and ship on.

Prompt it with AI

2-4 weeks $200+ in tool spend

Even strong models need weeks of prompting before auth, webhooks, and deploy configs work in production.

  • Days lost re-explaining OAuth callbacks, Stripe webhooks, and session cookies every session
  • Cursor, Claude, and API credits add up before you have something you trust to deploy
  • Edge cases show up live: entitlement checks, email deliverability, Workers vs Node session quirks
  • Every new prompt thread reinvents the same SaaS glue with no shared upgrade path

Hey, I'm Rishi.

Rishi Raj Jain
Rishi Raj Jain @rishi_raj_jain_

I'm a software engineer and technical writer. Every client project came with the same rebuild: a different database, a different payment processor, a different email provider. Same auth flows, same webhook handlers, same wasted weeks.

I built LaunchFast so you never start from zero again. Pick the providers your project needs on day one, or swap them later without tearing apart your codebase.

What people are saying

110+ developers ship with LaunchFast in production. Here is what they say about skipping the boilerplate.

Frequently asked questions

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

What do I get exactly?
1/ The full Astro, SvelteKit, or Next.js repo: auth, payments, database, email, storage, UI components, and API routes already wired. 2/ Step-by-step docs to configure your providers, customize the app, and deploy to production.
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?
You can. The question is whether auth and Stripe webhooks are the best use of your next two weeks, or your product is.
Can I get a refund?
No - all products are digital.
Ready to ship?

Your product deserves more than another week on Stripe webhooks. Get your starter kit and ship this week.
