Key takeaways

  • The platforms themselves are run by companies that fix security issues. The larger risk is in your app: the data rules, keys and payment logic the AI wrote for you.
  • Real incidents show both sides: a platform flaw at Base44, fixed within a day, and a pattern of weak database rules in apps built with Lovable.
  • Treat what the tool generates as a first draft. Four checks cover most of the risk before real users arrive.

“Is Lovable safe?” is one of the first questions founders ask once their app works. The honest answer has two parts, because there are two different things to trust: the platform you build on, and the app the platform builds for you. They fail in different ways and are fixed by different people.

This post separates the two, looks at what the public incidents actually showed, and ends with the checks that matter before launch. It closes a series that started with the guide to making an AI-built prototype ready for real users.

What does the platform secure, and what is left to you?

Think of it as shared responsibility, the same way cloud providers describe it. The platform secures its own infrastructure, accounts and the code that runs the builder. You are responsible for your app’s behaviour: who can read which data, which keys ship to the browser, how payments are confirmed, and whether there are backups.

The catch with AI builders is that the platform also writes your app’s code, so it is easy to assume it is responsible for the second part too. It isn’t. The tool generates code that works; whether that code is safe for your data is still your decision, and your liability.

What did the public incidents show?

Base44: a platform flaw, fixed fast. In July 2025, Wiz researchers found that Base44, the AI app builder owned by Wix, let an attacker register an account on apps meant to be private, bypassing single sign-on, using only the app’s ID, which was visible in its URLs. Wix fixed it within 24 hours of the report and said it found no evidence that any customer was affected (Wiz). That is the platform half working as it should: a vendor problem, fixed by the vendor.

Lovable: a pattern in generated apps. Also in 2025, a researcher scanned 1,645 projects built with Lovable and found 170 with database access rules weak enough to expose data to anyone, including names, emails, API keys and payment details (Matt Palmer). Lovable later added a security scanner, but the root cause sat in each app’s Supabase rules, the part that belongs to the app owner.

Across tools: the same gaps. Escape, a security firm, scanned 5,600 apps built with AI tools and reported more than 2,000 highly critical vulnerabilities and more than 400 exposed secrets (Escape). The findings are not specific to one builder; they follow from how prototypes are generated.

Does the choice of tool matter?

Less than you’d think. Lovable, Bolt, Base44, Replit and code editors like Cursor differ in how much they host for you and how much code you see, but they share the same weakness: they optimise for a working feature, not for what an attacker would try. A tool with built-in security scanning helps, and you should run it. It doesn’t replace checking the rules that protect your users’ data.

What does matter is whether you can see and own the code. With the code in a repository you control, a developer can review it, fix it and take it elsewhere. That is easier with some tools than others; for one path, see leaving Lovable with your code.

The four checks before real users

If you do nothing else before launch, do these. Each links to a full guide in this series:

  1. Database access rules. Every table has row-level security with policies, and a stranger with your public key can’t read other people’s data. See Supabase RLS for AI-built apps.
  2. No secret keys in the browser. Search your site’s JavaScript for secret keys and move those calls to the server. See secret keys in your frontend.
  3. Payments confirmed by the server. Orders become paid only through a verified Stripe webhook. See five Stripe bugs in AI-built apps.
  4. Backups and a paid plan. Free database plans are for development; Supabase’s free plan, for example, has no automatic daily backups (Supabase). And as the app grows, see why AI-built apps get slow.

So, is Lovable, Bolt or Base44 safe for real users? The platforms are as safe as any hosted service. Your app is as safe as the rules it was generated with, until someone checks them.

Frequently asked questions

Is Lovable safe to use?

Lovable is safe to build with, but the apps it generates need review before real users. The main risk found in Lovable-built apps has been weak Supabase row-level security, so check that every table has policies and that no one can read other users’ data with your public key.

Was Base44 hacked?

In July 2025, Wiz researchers disclosed a flaw that let attackers access private Base44 apps using only the app’s ID. Wix fixed it within 24 hours and said it found no evidence that customers were affected.

Which AI app builder is most secure?

No builder makes the generated app secure on its own. Choose one that lets you own and export the code, run its security scanner, and have the database rules, secret keys and payment logic reviewed before launch.
