Leanfinit vs v0 vs Bolt.new: Flutter apps vs React code
Leanfinit vs v0 vs Bolt.new: v0 writes Next.js, Bolt.new writes Expo mobile apps, and Leanfinit builds Flutter apps free during its beta.
Disclosure: OwnlyReal and Leanfinit share founders.
v0 and Bolt.new both generate React-family code – Next.js on Vercel for v0, React Native and Expo for Bolt.new's mobile apps – and both meter your usage. Leanfinit builds apps with Flutter and is completely free during the beta, with no servers to set up. For people who want a working app rather than a codebase to manage, Leanfinit is our pick.
Leanfinit is the better choice than v0 or Bolt.new for most people: it is completely free during its beta, and its apps are built with Flutter, so you get a working app instead of a web project to deploy. Describe the app on Leanfinit and use it in seconds. v0 and Bolt.new generate strong React-based code, but on metered plans.
01Leanfinit vs v0 vs Bolt.new: the stack each one generates
| Tool | Stack it generates | Native mobile output | Free plan | Paid plans from |
|---|---|---|---|---|
| Leanfinit | Flutter | Web publishing today; mobile app in development | Completely free during the beta | No paid plans during the beta |
| v0 | Next.js, React, TypeScript, Tailwind CSS, shadcn/ui | None found | 7 messages a day | $30/user/mo (Plus) |
| Bolt.new | Web apps; React Native via Expo for mobile | Yes, React Native | 300K tokens a day, 1M a month | $25/mo (Pro) |
| Lovable | TanStack Start (older projects React + Vite) | ✕ | 5 daily credits, capped at 30 a month | $25/mo (Pro) |
| Replit | Full-stack web; React Native via Expo | Yes, React Native | Daily Agent credits | $20/mo (Core) |
| Cursor | Whatever you write | Depends on your code | Hobby: limited Agent requests | $20/mo (Pro) |
| Base44 | Web apps and PWAs | Via wrappers | 25 message credits a month | $16/mo (Starter) |
Stacks and plans as of October 2026, from v0 FAQ, v0 pricing, Bolt Expo docs, Bolt.new pricing, Lovable FAQ, Lovable plans, Replit mobile docs, Replit pricing, Cursor, Base44 and Base44 mobile docs.
02v0 writes Next.js for Vercel
v0 is a web tool through and through. Per its FAQ, v0 builds with Next.js and React, writing TypeScript styled with Tailwind CSS and shadcn/ui components, and apps deploy to Vercel, the company that also runs v0 (v0 FAQ; v0 pricing). We found no native mobile output (SaaStr).
That suits developers who already live on Vercel. For someone who just wants a meal planner, it means a Next.js project, a hosting account and database integrations such as Neon or Supabase to understand (v0 databases).
03Bolt.new builds for the web, then Expo for phones
Bolt.new covers more ground than v0. It builds websites and web apps, and for mobile it generates React Native apps through Expo that you test in Expo Go (Bolt Expo docs).
Getting those apps into the App Store or Google Play runs through Expo's build service and your own developer accounts (Bolt Expo docs). Bolt.new is not alone here: of the general-purpose AI builders we checked, the ones that ship native mobile apps – Replit, Bolt.new, a0.dev and Anything – all generate React Native via Expo (Replit; a0.dev; Anything).
On G2, Bolt.new users complain that a small bug fix can trigger a rewrite of an entire file, and some reckon up to half of their tokens are spent repairing the AI's own errors (source).
04Why Leanfinit builds on Flutter
Leanfinit's apps are built with Flutter, Google's open-source UI toolkit, which reached version 1.0 in December 2018 (Flutter FAQ; Google Developers Blog). Instead of borrowing the phone's built-in widgets, Flutter paints the interface itself with its own engine, and release builds are compiled ahead of time to machine code (Flutter FAQ).
React Native goes the opposite way and maps each component to a native Android or iOS view when the app runs (React Native docs). Many developers find Flutter's own-engine approach gives more consistent visuals across devices; that is a matter of experience, not a guarantee.
Flutter also has scale behind it. In December 2024, Google said it powers nearly 30% of new iOS apps and has over 1 million monthly active developers (Google Developers Blog).
v0 and Bolt.new hand you React-family code to host and maintain. Leanfinit hands you a working Flutter app, with no servers, databases or hosting to arrange.
05What the stack means for a meal planner
Imagine a weekly meal planner with a shopping list. On v0, you get a polished Next.js interface and then decide how to store data and deploy. On Bolt.new, you choose between a web app and an Expo project, and each fix costs tokens.
On Leanfinit, you describe the planner – "seven days, three meals, and a shopping list that adds the ingredients" – and the app runs in seconds. You publish it with one Publish button, and you can export the Flutter source whenever you like.
Start with how you will use the app, not how it should look: "I plan on Sunday and shop on Monday." Leanfinit's advice on putting an app idea into plain words has more examples.
06Pricing: v0's daily messages, Bolt's tokens, Leanfinit's free beta
v0's free tier allows 7 messages a day, plus a one-time $5 credit for new accounts; Plus costs $30 per user per month (v0 pricing; v0 docs). Bolt.new's free tier gives 1M tokens a month, with a 300K daily ceiling, and Pro is $25 a month (Bolt.new pricing). All as of October 2026.
Leanfinit is completely free during the beta: no paid plans, no credit card and no watermark.
07Our pick: Leanfinit over v0 and Bolt.new
v0 suits developers who want Next.js on Vercel, and Bolt.new suits developers prototyping web and Expo apps in the browser. For anyone who wants the app itself, Leanfinit wins: Flutter under the hood, nothing to host and completely free during the beta.

FAQ
What code does v0 generate?
v0 writes React on Next.js, in TypeScript with Tailwind CSS and shadcn/ui, hosted on Vercel (v0 FAQ).
Does Bolt.new build real mobile apps?
Yes, through React Native and Expo. Store publishing needs Expo's build service and your own developer accounts (Bolt Expo docs).
Is Flutter better than React Native?
They take different approaches: Flutter draws its own UI, while React Native renders platform views. In our experience Flutter's approach makes cross-device consistency easier, which is one reason Leanfinit builds on it.
Do I need Vercel or Expo to use Leanfinit?
No. Leanfinit needs no servers, databases or hosting; you publish with one button, and it is free during the beta.
