If you're looking for the cheapest AI app builder, the honest way to compare is total cost to get a working app — not just the sticker price. GenVibe is free to start with no credit card, paid plans begin at $12/month, and one-time credit packs start at $5. And unlike most cheap builders, it builds real mobile apps as well as web.
Cost is one of the two reasons people leave the bigger AI builders (the other is mobile). Many charge more to get past the free tier, and several are web-only, so if you need an iOS/Android app you're paying for a second tool on top. GenVibe folds web and mobile into one affordable plan.
This page lays out exactly what you get for free, what the paid tiers cost, and why "cheapest" should mean value — a real, exportable app you own — not a stripped-down demo.
What you get for free
You can sign up with Google and start building immediately on a one-time pool of free credits — no credit card. Every feature is included on the free tier: web and mobile builds, live preview, code export, Figma and screenshot import, and a Supabase backend.
The free tier uses Claude Sonnet, a fast and capable model that handles most apps well. It's enough to build a genuine working app and decide whether GenVibe is right for you before paying anything.
- Free to start — no credit card, one-time credit pool
- Every feature included: web + mobile, preview, export, Figma/screenshot, Supabase
- Real, exportable code — no lock-in, download or push to GitHub anytime
Paid pricing, in plain numbers
When you need more, Standard starts at $12/month and unlocks Claude Opus (the most capable model) plus a monthly credit refill you can scale from 100 up to 2,000 credits. Pro is $99/month with 750 credits and priority processing.
Need a little more before your next refill? One-time credit packs start at 50 credits for $5 and go up to 600. Purchased credits don't expire while your plan is active, so you're never forced into a bigger subscription just to finish a build.
- Standard: from $12/mo, 100–2,000 credits, Claude Opus unlocked
- Pro: $99/mo, 750 credits, priority processing
- Credit packs from $5 (50 credits) — top up without upgrading
- Web and mobile both included on every plan
"Cheapest" should mean best value
A low price on a tool that locks you in, or that only builds websites, isn't actually cheap — you pay later in a rewrite or a second subscription. GenVibe keeps the real cost low in the ways that matter: you own standard, exportable code, and one plan covers both web and mobile.
So the practical comparison isn't just "which free tier is biggest." It's "which tool gets me a real app I own, for the least total spend?" For anyone who wants mobile — or just doesn't want to pay web-only prices — GenVibe is built to be that answer.

Frequently asked questions
What is the cheapest AI app builder?
GenVibe is among the most affordable: it's free to start with no credit card, paid plans begin at $12/month, and one-time credit packs start at $5 for 50 credits. Crucially, it builds both web and real mobile (React Native / Expo) apps, so you don't pay for a second tool to get a mobile app.
Is there a truly free AI app builder?
GenVibe is free to start with a one-time pool of free credits and no credit card required. Every feature is included on the free tier — web and mobile builds, live preview, code export, and a Supabase backend — using Claude Sonnet.
Do I need a subscription to use GenVibe?
No. You can build for free on your starter credits, and if you need more you can buy a one-time credit pack (from $5) without subscribing. Subscriptions (from $12/month) add a monthly refill and unlock Claude Opus, but they're optional.
Is a cheap AI app builder any good for real apps?
It depends on whether you own the output. GenVibe generates standard, exportable code (no lock-in), so a low price doesn't mean a throwaway result — you can export to GitHub or download the project and keep building anywhere.
Can a cheap AI app builder make mobile apps too?
Most affordable builders are web-only. GenVibe includes real React Native / Expo mobile apps on every plan, including the free tier, and lets you preview them on your phone via Expo Go — so mobile isn't an expensive add-on.
What happens to purchased credits if I cancel?
Purchased (one-time) credits don't expire while your plan is active. If your account returns to the free tier, unused purchased credits are forfeited — see the pricing and billing pages for details.
