Choose Lovable, Bolt.new or v0 if what you want is a React web app or SaaS front-end that you will host yourself, and you value their polish and their integrations with hosting and Supabase. Choose App Builder Agent if you want the same describe-and-refine workflow but need an Android app (installable APK or Play Store build) as well as a website, or a game or a scheduled workflow. All four generate real code from a prompt and show it to you; only App Builder Agent produces a phone app. None of them builds iOS apps.
Who each tool is for
Lovable, Bolt.new and v0 belong to the same generation of tools: you type a description, an AI writes a React project, a live preview appears, and you keep editing by chat. They are strong at web front-ends: landing pages, dashboards, SaaS prototypes, internal tools. Lovable leans on Supabase for backends and publishes to its own hosting; Bolt.new runs a full development environment in the browser and can deploy to hosting providers; v0 comes from Vercel and is strongest at generating React and Tailwind interfaces that you drop into a Next.js project. In all three the output is a website. None produces an Android APK or an iOS app; if you need a phone app you would wrap the site or rebuild it.
App Builder Agent uses the same workflow (describe, preview, refine, read the code) but targets more than the web. A project can be a React Native or Flutter mobile app that becomes an installable Android APK or a signed APK plus AAB for Google Play, a website published on appbuilderagent.com at /p/your-name/, a web or mobile game, or an AI workflow that runs on the platform's servers on a schedule. The agent can add a hosted backend (database, auth, files) and writes your API keys into a .env file when asked. Sign-in is with a Google account and nothing is installed. It suits people whose product needs to be on a phone, and people who want one account for the app, its marketing site and its automations.

Choose Lovable, Bolt.new or v0 if
- Your product is a web application and will stay one: a SaaS dashboard, an admin panel, a browser tool.
- You want the site on your own domain name from the tool's own hosting on day one.
- You already use Supabase, Vercel or GitHub and want the generated project to slot straight in.
- You are a developer who wants a strong starting point in React and will finish in your own editor.
- You want v0-style component generation to paste into an existing Next.js codebase.
Choose App Builder Agent if
- You need a phone app: an APK your customers or staff install, or a listing on Google Play.
- You want a website and an app from one account, described the same way, with the same login.
- You want the agent to add a hosted backend without you creating a Supabase project and wiring keys.
- You also want scheduled automations (a daily report, an auto-reply, an API poller) built by description.
- You want a landing site or business page quickly and are happy with an appbuilderagent.com address to start; the landing sites in the gallery show what the output looks like.
- You prefer a low fixed price: the free plan needs no card and Member is $1.49 per 30 days at the time of writing.
The same product in each tool
Take a common launch: a landing page that explains a service, collects sign-ups, and a companion app that customers use after they sign up. In Lovable or Bolt.new you describe the landing page and get a React site with a hero, features, pricing and a form; add Supabase for the sign-ups and deploy it. That part is excellent. The "companion app" then becomes a responsive web page, because neither tool produces an APK.
In App Builder Agent you describe both, in two projects, in the AI website builder and the app builder. For the site:
Then for the app: "Build an Android app for Northline's customers: sign in, book a walk, see the walker's arrival, get a photo report after each walk. Hosted backend." Both appear as live previews within minutes; the site publishes at appbuilderagent.com/p/northline/ and the app becomes an APK from the Preview tab, or a signed APK and AAB for Google Play. The landing-page details are in landing page for your app or business, and the app side in dog walking and pet sitting business app.
What to expect if you switch
From Lovable, Bolt.new or v0 to App Builder Agent. Because all of them produce real code, you keep everything you built. For a website, export your project and use it as the reference while you describe the site to App Builder Agent, or ask the agent to reproduce specific sections from your source. For a mobile app, there is no automatic conversion from React to React Native; describe the app and let the agent write it natively, reusing your API and data model. Expect the app's first version in a session. You gain the APK and Play Store build, the hosted backend and workflows; you lose their own-domain hosting (export and self-host if you need that) and their tighter Vercel or Supabase integrations.
From App Builder Agent to Lovable, Bolt.new or v0. Export the Vite site project on a paid plan and open it in any of them or in an IDE; it is standard React. The mobile app does not move, since they do not build mobile apps, but the exported React Native or Flutter project runs anywhere those toolchains run.
Using both. A sensible split is a web SaaS built in Lovable or Bolt.new, with App Builder Agent producing the Android app that talks to the same API. Put the API base URL and key in the App Builder Agent project's .env file and describe the screens.
Tip: if you are unsure whether you need a native app at all, ship the website first and watch whether people ask for "an app". Convert a website into an Android app explains what changes when you do, and why a plain WebView wrapper can be rejected by Google Play under its minimum functionality policy.
Costs and hosting
Lovable, Bolt.new and v0 publicly list free tiers with limited credits and paid plans starting around $20-25 a month at the time of writing, with hosting either included or handled by a provider you connect. App Builder Agent's free plan gives 500K AI tokens a month (with a free APK download), with all features and no card; Member is $1.49 per 30 days for 5M tokens, unlimited APK builds and source export; Pro ($5.72), Business ($31.12) and Max ($11.01) add tokens. A small site or app typically takes a few hundred thousand tokens to build and iterate. Websites are hosted at appbuilderagent.com/p/your-name/ at no extra charge; your own domain name is not supported on that hosting, so export and self-host if you need one. Google Play adds a one-time US$25 registration if you publish the app. The rest of the field, including the visual no-code tools, is compared in best AI app builders in 2026.
Frequently asked
Can Lovable or Bolt.new make an Android app?
Not directly. They generate React web apps that you host as websites; you would need to wrap or rebuild the result to get an APK. App Builder Agent generates React Native or Flutter mobile apps and produces an installable Android APK and a signed APK plus AAB for Google Play.
Are they all prompt-driven in the same way?
Yes. In all of them you describe what you want, see a live preview and refine by chat, and the generated code is visible. The difference is the target: Lovable, Bolt.new and v0 produce web projects; App Builder Agent produces mobile apps, websites, games and workflows.
Which one is cheaper?
Lovable, Bolt.new and v0 have free tiers with limited credits and publicly listed paid plans starting around $20-25 a month at the time of writing. App Builder Agent's free plan gives 500K AI tokens a month; Member is $1.49 per 30 days with unlimited APK builds and source export.
Where is a website from App Builder Agent hosted?
On appbuilderagent.com under /p/your-name/. You can export the complete Vite project on a paid plan and host it anywhere you like, which is the route if you want it on your own domain name.
Do any of these build iPhone apps?
No. Lovable, Bolt.new and v0 produce web apps that run in Safari. App Builder Agent does not build iOS apps either; you export the React Native or Flutter source on a paid plan and build it with Xcode or Expo EAS on a Mac.
