SaaS template with login, auth, and payments: what to look for
Searching for a "SaaS template with login auth and payments" usually means one thing: you want a working product foundation, not another starter that stops at the landing page.
What to look for
A template that genuinely includes auth and payments needs four things:
1. Authentication providers wired up (not just a login button mockup)
2. Checkout session creation for one-time or subscription payments
3. Webhook handlers for payment events (created, renewed, failed)
4. A subscriptions table in the database
Where free templates fall short
Most free Next.js templates (Create T3 App, ixartz, Wasp) include auth but stop before payments. You get the login flow, then you're on your own for billing — which is typically 15-20 hours of additional work.
What a complete template includes
The CheapStack SaaS Starter ($49) includes NextAuth v5 with GitHub and Google login, Polar.sh checkout, a users table, and a subscriptions table. The SaaS Boilerplate ($59) goes further: Stripe + Polar.sh dual billing, webhook handlers for both, multi-tenancy, and an admin dashboard.
The honest tradeoff
- Free template + build billing yourself: $0 upfront, 15-20 hours of work
- CheapStack SaaS Starter: $49 once, billing pre-wired
If your time is worth more than ~$3/hour, the paid option wins. If you genuinely have time and zero budget, the free path works — you just won't ship as fast.
