Is Lovable secure enough to launch a paid app, given the Supabase RLS issues?
Quick answer
Yes, Lovable is secure enough to launch a paid app if you do the security basics before going live: enable Supabase Row Level Security with correct policies, run Lovable's built-in security scan, and review before launch. The RLS risk is real, but it applies to any AI-generated app and is fixable, not a reason to avoid Lovable.
Let us be direct about the concern, because it is legitimate. The documented risk is that AI-generated apps can ship with missing or misconfigured Supabase Row Level Security, which can leave database tables readable through the public anon key. This was highlighted publicly (CVE-2025-48757 referenced a study finding 170+ apps and 303 endpoints leaking data). That is a real problem worth taking seriously, and glossing over it would not serve you.
The crucial context: this is not fraud or a hidden flaw unique to Lovable. It is a general property of AI builders that connect to a database, and it comes down to one thing being switched on and configured correctly. Row Level Security is Supabase's mechanism for controlling who can read and write each row. When it is enabled with correct policies, the leak vector closes. The fix is well understood, and it is entirely within your control.
Lovable has responded to this. Lovable 2.0 (April 2025) added a security scan feature, and the company publishes security best-practice guidance. Fair criticism is that the scan initially focused on whether RLS existed rather than whether the policies were actually correct, so do not treat a green scan as the whole story. Use the scan as a first pass, then confirm your policies genuinely restrict access the way you intend, ideally with a developer's eyes if the app handles sensitive or paid data.
Here is the practical pre-launch checklist to make it safe: enable Row Level Security on every table, write policies that scope data to the right user, run the security scan, test by trying to access data you should not be able to, and review before you flip it live. Because you own the code and it is standard Supabase, you or any developer can audit this directly. We run IdeasGPT on Lovable, and treating security as a required launch step rather than an afterthought is exactly how you build with confidence.
Who this is right and wrong for: it is right for founders launching paid or user-data apps who are willing to complete the security checklist (which does not require deep expertise). It is the wrong mindset to prompt once and launch a payment-taking app without any security review; that would be unsafe with any tool, not just Lovable. Do the basics and it is genuinely safe to build on.
