Start from the bottleneck
- Need login, sessions, and email verify? Prefer an auth kit.
- Need Checkout, webhooks, and entitlements? Prefer a billing kit.
- Need a whole app shell? Prefer a full SaaS boilerplate.
- Need an internal console? Prefer an admin dashboard kit.
Read the listing carefully
- Confirm stack tags match what you already know (e.g. Next.js + Prisma + Stripe).
- Read setup instructions before paying - missing env clarity is a red flag.
- Check screenshots and demo URL if provided.
- Prefer kits that document migrations, webhooks, and deploy steps.
Use the Auth architecture picker if you are unsure between cookie JWT, sessions, and OAuth-first - then filter the marketplace for auth kits.
