LaunchKit

Build your web app
from the first prompt.

A production-ready starter kit built for AI coding tools.

Start with the stack, screens, design system, and integration points already in place. Open it in Claude Code, Codex, Cursor, or any AI coding tool, then prompt your features and ship.

In 2026, everybody builds with AI, even non-coders. The hard part is not the prompt. It is giving your AI coding tool the right stack and integration points, so it can build something real instead of guessing.

Authentication

Do not let sign-in slow down your launch.

Start with the auth flows users expect: email, social login, password reset, MFA, passkeys, roles, SSO, and protection against abuse. The screens are already designed so your AI coding tool can adapt and wire them instead of inventing them from scratch.

Start with industry-standard auth flows, not empty forms.Every integration point is mapped so your AI coding tool knows where to connect the provider, session, roles, and security rules.

Payments

Start taking payments without starting from scratch.

Start with a billing page, checkout flow, customer portal, and subscription UI already in place. Connect Stripe first, then keep the same product surface as you add or switch providers later.

Stripe customer portal
Let customers update cards, download invoices, and cancel on their own from Stripe’s hosted portal, without you maintaining a separate billing UI.
Payments without the fear

Start with the provider path that gets you live.

Stripe is the simplest place to start. When you need another provider, keep the same billing flows and have your AI coding tool map the new checkout, portal, and webhook logic onto the existing seams.

Subscriptions & billing
Start with plans, billing history, and subscription management already shaped into the product. Connect your pricing and let the payment provider handle the money movement.

More providers later
Keep the same billing experience as you add Lemon Squeezy, Polar, PayPal, or merchant-of-record providers later. The product surface stays the same while the provider changes underneath.
Email & growth

Email flows, already part of the product.

Start with newsletter capture, broadcasts, and contact flows already in place. Connect your email provider once, keep everything inside the product, and stop wiring separate tools just to talk to users.

Email your users

Write and send broadcasts from inside the app instead of stitching together a separate email tool. Connect your provider once and keep user communication close to the product.

Contact form

Start with a real contact flow that lands in your inbox. Your AI coding tool wires the provider instead of you building a backend just to receive messages.

The last mile is already in place.

Storage, languages, notifications, deploys, and analytics are already part of the foundation. Your AI coding tool is not inventing the last mile from scratch.
