Softonic’s piece on Gemini Canvas turning prompts into deployable apps landed in the middle of a real shift. The field that used to be “AI helps you write code” has split off a new category that takes a one-paragraph idea and ships a working frontend, sometimes a backend, sometimes a deploy URL. The Canvas demo with Paris Hilton was the consumer flash, but developers had already been comparing v0, Bolt, and Lovable for months.
We tested 8 AI prompt-to-app builders on a Windows 11 laptop, a MacBook with Apple Silicon, and a Linux desktop, running the same prompts through each tool. The benchmark prompts ranged from a single-page form to a small CRUD dashboard with auth, and the comparison covers what ships, what runs locally, what costs after the free credits, and how the code looks under the hood.
What to look for in an AI prompt-to-app builder
A few criteria separate the tools that produce a deployable artifact from the ones that look impressive in a screenshot.
- Where the code lives. Some tools (v0, Bolt) hand you a real project you can clone; some keep the code inside their workspace (Lovable, Canvas).
- What the model can edit. Whole-app edits, component-level edits, or single-line edits all behave differently when you ask for a change later.
- Backend and database support. A form that posts to nothing is easy. A working API with persistence is the harder feature.
- Deployment story. Vercel, Netlify, and Replit deploys are first-class for some tools; others need a manual export.
- Source-code quality. Re-prompting a messy codebase is its own job. The cleaner the initial code, the longer the agent stays useful.

The apps
1. Gemini Canvas, best for quick app prototypes inside Gemini
Gemini Canvas for prompt-to-app sits inside Gemini Advanced and turns a chat description into a working interactive artifact in the same window. The June update added the deeper code generation and a share link that opens the app in a browser without an install step. For drafting an idea and showing it to a stakeholder, Canvas is the fastest path from idea to live URL we tested.
Where it falls short: the apps stay inside Google’s environment. There is no clean export to a GitHub repo, the deployment is the share link rather than a real Vercel-style deploy, and editing complex apps still hits the limit of one-shot prompt iteration.
Pricing:
- Free: limited Canvas runs inside Gemini’s free tier.
- Paid: Gemini Advanced at $19.99/month with deeper Canvas usage.
Platforms: Web (Gemini in Chrome, Edge, Safari, Firefox).
Download: Gemini Canvas
Bottom line: the right pick if the goal is a same-day demo that anyone can open in a browser.
2. v0 by Vercel, best for production-ready React and Next.js
v0 is the workhorse for engineers who want output that ships. The model produces shadcn/ui components on top of Tailwind and Next.js, and the generated code is close enough to handwritten that the diff against a senior engineer’s pull request is small. The Vercel integration ships the app to a real preview URL on first run.
Where it falls short: v0 leans React-heavy. Non-React stacks (Svelte, Vue, plain HTML) are second-class. The free tier credits run out faster than the marketing implies once you start iterating.
Pricing:
- Free: monthly credits, enough for a few small projects.
- Paid: Premium $20/month for higher quotas.
Platforms: Web.
Download: v0 by Vercel
Bottom line: the right pick for engineers who already build on Next.js and want the AI to slot into their existing workflow.
3. Bolt.new, best for full-stack apps that run in the browser
Bolt.new by StackBlitz runs Node, Vite, and the full dev toolchain inside the browser via WebContainers, which means the app the agent built actually runs without leaving the page. The full-stack story is genuine: the agent installs npm packages, runs migrations, and starts a dev server in the same window.
Where it falls short: WebContainers are powerful but the runtime is still a sandbox, so libraries that need native modules fail. Token usage on long iteration sessions adds up.
Pricing:
- Free: capped token budget per day.
- Paid: Pro $20/month for higher token limits.
Platforms: Web.
Download: Bolt.new
Bottom line: the right pick when you want to see the running app, not just the code, in the same browser tab.
4. Lovable, best for non-technical founders shipping MVPs
Lovable is the prompt-to-app tool aimed at people who do not read code. The agent generates a React frontend wired to a Supabase backend by default, and the editing experience is a chat panel on the right with a live preview on the left. The “edit only this section” prompts work better here than in v0 or Bolt for users who are not comfortable editing files directly.
Where it falls short: the Supabase coupling is a strength and a limit. Bringing your own auth or database is awkward. Power users prefer v0 once they learn the React conventions.
Pricing:
- Free: 5 credits per day for new accounts.
- Paid: Starter $25/month, Pro $100/month for higher message and project counts.
Platforms: Web.
Download: Lovable
Bottom line: the right pick if the user typing the prompt does not want to see a single line of code.
5. Replit Agent, best for backends with persistent runs
Replit Agent lives inside Replit’s full IDE and runs the generated app inside a real container with persistent hosting. The agent can install dependencies, edit files across the project, and deploy the result on Replit Deployments with a real URL and zero extra setup.
Where it falls short: the cold-start performance on the free tier is noticeably slow. Iteration on long sessions burns through the included compute.
Pricing:
- Free: limited Agent runs and starter compute.
- Paid: Core $25/month, Teams $33/user/month.
Platforms: Web, Windows desktop, macOS desktop.
Download: Replit
Bottom line: the right pick if the app needs a server, a database, and a stable URL out of the gate.
6. Cursor Composer, best for engineers who want the AI inside their IDE
Cursor Composer is the multi-file edit mode inside the Cursor editor. Composer is not a prompt-to-app tool in the strict sense, but the recent agent updates make it close enough that “build a full Next.js app from this spec” works as a workflow inside your real repository, with the model editing across files and running the dev server in the same window.
Where it falls short: Composer assumes you already have a project (or are willing to start one) on disk. It is not a zero-setup “give me a deploy URL” tool.
Pricing:
- Free: 14-day Pro trial; Hobby tier afterwards.
- Paid: Pro $20/month, Business $40/user/month.
Platforms: Windows, macOS, Linux.
Download: Cursor
Bottom line: the right pick if your output is a Git repo and you want the AI to live inside the editor you already use.
7. Claude Artifacts, best for single-page apps and visualisations
Claude Artifacts turns a conversation into a runnable artifact inside the same chat window. For single-page apps, data visualisations, and React components, Claude generates the code and an inline preview that you can resize and edit by re-prompting.
Where it falls short: Artifacts is a single-page model. Multi-file projects, real backends, and persistent storage are not the format. The desktop apps are stable; the export story is copy-paste.
Pricing:
- Free: capped usage.
- Paid: Pro $20/month, Max from $100/month for the higher limits.
Platforms: Web, Windows, macOS.
Download: Claude
Bottom line: the right pick when the artifact is a single page that demonstrates a point.
8. Tempo Labs, best for React Native apps from a design
Tempo Labs sits closest to a visual builder: a Figma-style canvas where you drop components and the AI fills in the code. The output is React or React Native, and the visual editor lets non-engineers tweak layout without re-prompting the model every time.
Where it falls short: the React Native side still lags React on the web. Real native module integration is on you. The pricing climbs fast for teams.
Pricing:
- Free: capped for personal projects.
- Paid: Pro $30/month, Team $80/seat/month.
Platforms: Web.
Download: Tempo Labs
Bottom line: the right pick if the deliverable is a mobile prototype that started from a design.

If the user holding the keyboard does not read code, use Lovable.
If the app needs a backend and a stable URL, use Replit Agent.
If you already work in an IDE all day, use Cursor Composer.
If the deliverable is a single-page demo with a chart, use Claude Artifacts.
If the goal is a mobile app from a visual design, use Tempo Labs.
FAQ
What is the best AI app builder for non-coders?
Lovable is the cleanest pick for people who do not read code. The chat-and-preview model and the default Supabase backend remove the configuration steps that trip up new users.
Can AI prompt-to-app builders ship a real backend?
Yes. Replit Agent, Bolt.new, and Lovable all wire a backend by default. v0 is frontend-focused but pairs cleanly with a separate API. Gemini Canvas is closer to a frontend prototype than a full-stack app.
Are these tools free to try?
All eight have a free tier. The paid plans start around $20/month and add credits or token quotas. Iteration on a real project usually consumes the free tier in a few days.
Which one writes the cleanest code?
v0 and Cursor Composer produce code closest to what a senior engineer would write, in part because their training leans on production React patterns. Bolt is close behind. Lovable and Canvas trade code quality for editing simplicity.
Can I export the generated code to GitHub?
v0, Bolt.new, Replit Agent, and Cursor support clean Git export. Lovable supports it on paid plans. Gemini Canvas and Claude Artifacts are weaker on this dimension; you copy code out manually.
