Auth & payments
Sign-in and subscriptions, solved on day one.
NextAuth and Stripe (plus Lemon Squeezy) are already connected — protected routes, paid tiers, and billing webhooks work out of the box.
Drop-in authentication
Email and OAuth providers via NextAuth, with protected and paid route examples included.
Stripe & Lemon Squeezy
Checkout, webhooks, and entitlement checks ready to wire to your own products.
Protected route patterns
Copy the protected, protected-and-paid, and partially-gated page examples straight into your app.
Content & docs
A docs site and blog that ship with your product.
Fumadocs and Content Collections power a fast, searchable documentation site and MDX blog — no separate CMS to run.
Fumadocs-powered docs
Full-text search, a sidebar tree, and MDX authoring, all rendered at the edge.
MDX blog included
Write posts in Markdown with frontmatter; the listing and post pages are already built.
SEO handled
Sitemaps, robots, and metadata are generated for every route automatically.
Features
Everything a SaaS needs, already wired together
Six building blocks you can toggle on as you grow — no stitching a dozen libraries together yourself.
Payments
Stripe and Lemon Squeezy checkout with webhook handlers and entitlement checks.
Bring any database
Adapters for Postgres, MySQL, SQLite/D1, MongoDB, and Redis — swap without rewiring.
Docs & search
Fumadocs with instant full-text search and a clean, navigable sidebar.
Transactional email & bots
Send email and Telegram notifications from server actions and route handlers.
Deploy anywhere
Standalone output plus adapters for Vercel, Fly.io, AWS Amplify, and Cloudflare Workers.
“I had auth, Stripe billing, and a docs site live before lunch. This starter kit paid for itself on the first afternoon.”
Alex Rivera
Founder, Shipfast Labs
Secure_defaults
Secure defaults, not security homework
The boring-but-critical parts — auth, secrets, and deploys — are configured the right way from the first commit.
Auth done right
Session handling, CSRF protection, and protected route middleware come configured, not as a TODO.
Secrets stay secret
Environment loading via dotenvx keeps API keys encrypted at rest and out of your bundle.
Deploy your way
Ship to Vercel, Fly.io, Amplify, or Cloudflare Workers with the adapter already included.
