The short answer: the cheapest AI app builder with the AI included is GenVibe. It's free to start (20 credits, no card), then $12/month for 100 build credits, with $9 for your first month. Most competitors start at $20 to $25 a month, and v0 at $30 per user. And GenVibe isn't a stripped-down tool to hit that price: it builds web and mobile apps, imports Figma designs and screenshots, and publishes your app for free.

One with small credit packs, no per-seat fee and no second balance. GenVibe sells 50 credits for $5 with no subscription, and its plans start at $12 a month.

How much do plain-language app builders charge for hosted production apps?
It depends on the publishing step more than the plan. GenVibe publishes to a free genvibe.app address on every plan, with custom domains on paid plans. Emergent charges at least 50 credits to put an app live, plus a monthly fee to keep it online. Check what going live and staying live cost before you build.
What’s the most cost effective AI app builder if I need to build a full stack app with a database?
GenVibe, at $12 a month. It builds full-stack web and React Native apps with a Supabase database and logins, and publishes them to a live URL: the same core features as tools that start at $20 to $30 a month.

The cheapest AI app builders, ranked by price
- GenVibe: $9 first month, then $12/mo. The lowest price with the AI included, free to start, and builds both web and mobile.
- Draftbit: $15/mo base ($12 billed yearly). A mobile-first builder, but the AI runs on your own Claude or ChatGPT subscription, or on credits you add, so the real cost is higher.
- Replit, Base44, Emergent, Rork: $20/mo. Replit and Emergent build web and mobile; Base44 builds web apps; Rork builds native iPhone and Android apps, but its free plan only designs.
- Lovable and Bolt.new: $25/mo. Both strong. Lovable is web only; Bolt.new also does Expo mobile apps.
- v0: $30 per user per month. Polished web apps, but the priciest entry, and it charges per seat.
Each tool's plans in full: Lovable pricing, Bolt.new pricing, Replit pricing, v0 pricing, Base44 pricing, Emergent pricing and Rork pricing.
Cheapest mobile app builders
If you need an iPhone and Android app, the field is smaller. Here's what each AI mobile app builder costs to start building:
| Builder | Paid from | Mobile stack |
|---|---|---|
| GenVibe | $12/mo (AI included) | React Native / Expo (one codebase) |
| Draftbit | $15/mo ($12 billed yearly) + AI usage | React Native / Expo |
| Replit | $20/mo | React Native / Expo |
| RapidNative | $20/mo (50 credits) | React Native / Expo |
| Emergent | $20/mo | React Native / Expo |
| Rork | $20/mo | Native Swift + Kotlin (two codebases) |
| Bolt.new | $25/mo | React Native / Expo |
To publish, every builder also needs an Apple Developer account ($99/year) and a Google Play account ($25 once). For the full breakdown, see the best React Native app builders.
Hidden costs to check before you pay
- Publishing fees. Emergent charges at least 50 credits to put an app live, plus a monthly fee to keep it online. GenVibe publishes to a free live URL on every plan. See Emergent pricing explained.
- Credits that expire. Some plans reset every month with no rollover. Lovable is the friendliest here: unused monthly credits roll over while you stay subscribed.
- Second balances. Base44 counts "integration credits" when your app's users trigger AI, email or file features, and Rork charges extra for iOS builds and cloud features. See Rork pricing explained.
- AI not included. Draftbit's plans are base plans; the AI runs on your own subscription or added credits.
- Per-seat pricing. v0 charges $30 for each user on Plus and $100 on Business.
Cheap doesn't mean limited
At $12/month, GenVibe does what the $20 to $30 tools do: full-stack web and mobile apps (React Native with Expo), Figma-to-code and screenshot-to-code, a Supabase database and logins, free publishing to a live URL, and custom domains on paid plans. You're not paying less for less: you're paying less for the same core capability.
How to choose
If price decides it, GenVibe is the clear pick: free to start and the cheapest to upgrade with the AI included. If you need a strength another tool is known for (v0 for Next.js polish, Lovable for web SaaS defaults, Replit for a full cloud IDE), weigh that against paying roughly twice as much. For most people building a real web or mobile app on a budget, the cheapest full-featured option wins. Try GenVibe free →
