Lovable vs Bolt vs v0: Which AI App Builder Fits Your Project?
Three AI app builders, three different bets. Lovable builds full apps with a backend for non-developers, Bolt runs a whole dev environment in your browser, and v0 is strongest at Next.js and UI. What each produces, where each struggles, and how to choose.
Lovable, Bolt.new and v0 all do the same headline trick: you type what you want, and a working web app appears. Under the surface they make different bets about who you are and what you'll do next. Here's how they compare, honestly, as of autumn 2026. Features move fast in this space, so check each tool's site before you commit money.
At a glance
| Lovable | Bolt.new | v0 | |
|---|---|---|---|
| Made by | Lovable | StackBlitz | Vercel |
| Aimed at | Non-developers building full apps | Builders who want to see and run the code | Developers and designers, Next.js-first |
| Typical stack | React + Vite + Supabase | Varies; React/Vite common, can do others | Next.js + shadcn/ui |
| Backend | Supabase or Lovable Cloud built in | Bolt Cloud / Supabase integrations | Next.js server code, Vercel integrations |
| Runs code | In the cloud preview | In your browser (WebContainers) | In a sandbox, deploys to Vercel |
| Code export | GitHub sync | Download / GitHub | GitHub / CLI |
| Natural host | Lovable hosting | Bolt hosting / Netlify | Vercel |
Lovable: the most complete "app from a chat"
Best for: someone who isn't a developer and wants a working product — logins, data, pages — without touching a terminal.
Strengths: opinionated stack (React + Supabase), so the pieces fit; strong at standard app shapes; friendly for iteration.
Watch for: security rules on the database are your responsibility (Supabase RLS); credits drain quickly in fix loops. (What is Lovable?)
Bolt.new: a dev environment in the browser
Best for: people who want to watch the code, see the terminal, and occasionally intervene.
Strengths: runs a real Node.js environment inside your browser tab, so you see installs, errors and files as they happen. Flexible about frameworks.
Watch for: browser-based runtimes have limits (some native packages and databases don't run there); large projects can get sluggish; token usage grows with project size. (How to deploy a Bolt.new app)
v0: Next.js and UI, the Vercel way
Best for: developers and designers who want high-quality React/Next.js UI and are happy on Vercel.
Strengths: excellent component and layout generation with shadcn/ui; produces idiomatic Next.js; deploys to Vercel in a click.
Watch for: it's most comfortable inside the Vercel ecosystem; backend features rely on Vercel's integrations; hosting elsewhere takes some adapting. (How to deploy a v0 app)
The things they all share
Whatever you choose, the same problems arrive after the demo:
- Fix loops. The AI breaks something, fixes it, breaks something else. (Stuck in an AI fix loop?)
- Secrets in the frontend. Anything in browser code is public. (Hide API keys)
- No staging, no backups, no monitoring by default.
- Growing out of the builder. Eventually you want a coding agent working on the code directly, plus a host you control.
How to choose
- "I'm not technical and need a full app with logins and data" → Lovable.
- "I want to see the code and terminal, and switch frameworks" → Bolt.
- "I want beautiful Next.js UI and I'm fine on Vercel" → v0.
- "I'm comfortable with a terminal" → consider skipping builders and using a coding agent like Claude Code directly on a real project.
Many people prototype in one of these, export to GitHub, then continue with a coding agent. That path works well because all three produce standard code.
The summary
- Lovable: the most complete app for non-developers.
- Bolt: the most transparent, with a real runtime in the browser.
- v0: the strongest Next.js/UI output, tied to Vercel.
- All three need the same production hardening once real users arrive.
EasySpawn is where a builder project goes next: a persistent server with your app, a Postgres database and Claude Code working on the code directly, on your own domain with daily backups. See how it works for AI-built apps or join the waitlist.

What Is Lovable? How the AI App Builder Works and Where It Stops
Lovable turns a chat description into a working web app: a React frontend, usually backed by Supabase for login and data. What it builds, what you actually own, what it costs to keep running, and the jobs you'll still need to do yourself.
