Lovable can take an idea to a working app remarkably quickly, and for testing an idea that speed is exactly what you want. Charging money changes the job. Paying users bring personal data, payment records and expectations, and the questions that matter stop being about features. This is what we would check before a Lovable app takes its first payment.
Your data lives in Supabase, and the rules are yours
Lovable apps typically use Supabase for the database and sign-in. The browser talks to the database directly, using a public key that anyone can read. What keeps each user inside their own data is row-level security: rules on every table that decide who can read or change which rows. Supabase's documentation says a table in an exposed schema without row-level security can be read and written by any role that has access to it, and that once row-level security is enabled, nothing is readable through the public key until policies allow it.
This is the problem behind CVE-2025-48757, disclosed in May 2025, which described Lovable-generated projects where missing or insufficient row-level security let data be queried directly with the public key.
Run the built-in scans, then go further
Lovable documents two built-in security scans, a quick scan and a deep scan, which flag common problems such as tables without per-record access control and leaked secrets. Run both. Lovable's own documentation also says the scans cannot guarantee complete security and do not replace a thorough security review, and it suggests a professional review for apps that handle sensitive data. Treat a clean scan as the start of the review.
Five questions to answer before launch
Know your way out before you need it
Ownership matters as much for an app built with a tool as for one built by a developer. Keep the code in a repository your company owns, know which accounts hold the database and the domain, and check that the app can run outside the builder if it ever has to. You may never leave. Knowing you could is what makes the platform a choice.
What client ownership means in practice
When to bring in an engineer
If your app stores personal or financial data, takes payments, or has started to break in ways the builder cannot fix, it is time for a person to read the code. The first step is always the same: find out what exists, test what it actually does, and write down the gaps.
