Auth and billing you don't have to debug.

Auth

Supabase email/password auth with SSR cookies, confirmation callback, and reusable clients.

Billing

Lemon Squeezy checkout, signature-verified webhook, and is_pro flag — no Stripe required.

Admin

Email allowlist, dashboard endpoints, service-role separation, RLS examples.

OG Images

Edge runtime, route segments not query params, Satori gotchas worked around.

PWA

Manifest, service worker, installable shell, and safe-area-ready viewport metadata.

Toasts & Modals

Production-tested patterns. SSR-safe. Theme-aware.

Analytics

Vercel Analytics mounted with a typed custom-event helper.

Sentry

Optional client, server, and edge configuration with signed-in user context.

6 /vs pages

Side-by-side comparisons with ShipFast, Supastarter, MakerKit, TurboStarter, Vercel templates, and "build from scratch."

14-day refund

Full refund, no questions asked. Email me and it's done.
