Comparison

Lovable vs Bolt: which AI app builder should you use in 2026?

The short version

Lovable is the better choice when the app needs real users, a database and login, because its Supabase integration does that in one step. Bolt is the better choice for fast prototypes, UI-heavy apps and non-React stacks, because everything runs in the browser tab. Both are $25 a month at the Pro tier. We scanned 628 apps built with them; the security section below is the part no other comparison has.

Lovable
Browser app builder

Lovable builds a full web app from a chat: React frontend, Supabase database and auth wired in, deployed on a URL, all without opening a file. It is the tool most non-developers reach for first, and it can export the repo to GitHub when you outgrow the chat.

Where it wins
  • Fastest path from idea to a working app with a real database and login
  • Supabase integration is the deepest of any builder
  • Unlimited collaborators for the price of one plan
  • Export to GitHub keeps you from being locked in
Where it falls short
  • Credits go quickly on iterative fixes; a stuck bug can eat a day's allowance
  • The generated Supabase setup ships the public key to the browser by design, and row level security is only as good as what you asked for
  • Harder to make precise changes once the app is large; most people finish in an editor
Pricing, verified September 2026
  • Free: 5 credits per day, capped at 30 per month
  • Pro: $25/month, 100 credits
  • Business: $50/month, 100 credits plus team features
  • Unlimited workspace members on every plan; you pay for credits, not seats
Bolt
Browser app builder

Bolt, from StackBlitz, runs a full Node environment in your browser tab, so the AI can install packages, run the dev server and show you the app without a backend round trip. It is the quickest of the builders for prototypes and supports a wide range of stacks, not just React and Supabase.

Where it wins
  • Fastest iteration loop of the builders because everything runs in the tab
  • More stack flexibility: Next.js, Astro, Svelte, Expo for mobile
  • Cheap to try seriously on the free tier
  • Good at one-shot prototypes and UI-heavy apps
Where it falls short
  • Tokens burn fast on big projects; a large file re-sent in context costs real money
  • Backend and auth are less turnkey than Lovable's Supabase flow
  • Long sessions degrade as the context fills; you learn to start fresh chats
Pricing, verified September 2026
  • Free: 1M tokens per month, 300K per day
  • Pro: $25/month for roughly 10M tokens (Bolt has adjusted the allotment more than once in 2026)
  • Teams: $30/member/month
  • Token-based, so long conversations and large files cost more than short ones

What our scans found

This is the part other comparisons cannot write. We statically scanned 2,148 public repos built with AI tools and probed 4,740 live apps, then published the anonymised data. Here is what it says about apps built with these two.

Lovable
32.1%
of 299 attributed repos had at least one high-severity finding

Lovable repos had the highest share of high-severity findings in our repo scans. Live, the recurring pattern is a Supabase anon key in the frontend with row level security not enforced on every table. Details

Bolt
17.9%
of 329 attributed repos had at least one high-severity finding

Bolt repos had roughly half the high-severity rate of Lovable repos in our scans. Hardcoded credentials, often a Firebase config or a third-party API key, were the top finding. Details

Repo rates are upper bounds from a static scanner and the corpora were sourced differently, so treat the numbers as directional. Method, limits and the CSVs are on the research page.

Which one should you pick?

Pick Lovable if

Your app has accounts, saved data and things only the owner should see. You want collaborators without paying per seat. You would rather have fewer choices and a working backend.

Pick Bolt if

You are prototyping, building something mostly frontend, or need a stack other than React and Supabase. You want the fastest possible loop and a generous free tier to test on.

Or both. A common path is Bolt for the first version, then rebuild the real one in Lovable once you know what you want, or export either to GitHub and finish in Cursor. Neither locks you in.

Frequently asked questions

Is Lovable better than Bolt?

For apps with users and data, usually yes, because Supabase auth and database come wired in. For prototypes, mobile, or non-React stacks, Bolt is better. They overlap less than people expect.

Is Lovable or Bolt cheaper?

Both are $25 a month for Pro. Lovable charges credits per message, so a stuck bug that takes twenty attempts costs twenty credits. Bolt charges tokens, so a big project with large files costs more per message. Small apps are cheap on both; which is cheaper for you depends on whether your work is many small messages or fewer large ones.

Which is more secure, Lovable or Bolt?

In our repo scans, 32.1% of Lovable apps and 17.9% of Bolt apps had at least one high-severity finding. That gap is mostly the Supabase pattern: Lovable ships the public anon key to the browser by design, which is safe only when row level security is enforced on every table, and it often is not. Bolt's most common issue was a hardcoded third-party key. Both are fixable in minutes once you know, which is why we suggest scanning before you share the link.

Can I move from Bolt to Lovable or the other way?

Not directly; each generates its own project structure. What you can do is export either to GitHub and keep working in an editor, or start over in the other builder with the same prompts. Most people who switch do the latter early, before the app is large.

Whichever you use, the output has the same handful of mistakes. Paste a URL or a public repo and see them in thirty seconds. No account.
