A single landing page is Unbounce's easy case. A multi-step funnel — landing page, upsell, downsell, each tracked and connected — is a genuinely bigger, if still bounded, build.
VIBE SCORE 94/100
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.
| Landing page | 99 |
| Stripe checkout | 88 |
| CRUD database | 95 |
Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
ClickFunnels costs $97/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 1 month.
Borderline. A single landing page is Unbounce's easy case. A multi-step funnel — landing page, upsell, downsell, each tracked and connected — is a genuinely bigger, if still bounded, build.
ClickFunnels costs $97/mo (about $1164/yr) as of 2026-08. That's what a working rebuild would save you.
One-click upsells (charge the same card again without re-entering details) need a real Stripe integration beyond basic Checkout Their visual funnel-mapping editor and huge template library represent real design and product investment Split-testing entire funnel variants, not just single pages, compounds the basic A/B testing problem
