Comparisons Lovable's built-in security scanner
Lovable security scanner alternative — what the built-in check misses
Lovable 2.0 includes a security scan that runs before you publish. It is built into the platform, costs nothing extra, sees the project it generated, and it will catch the most obvious misconfigurations before your app goes out. That combination — free, zero setup, already there — makes it the default for a very large number of vibe-coded apps, which is precisely why its limits are worth stating. Independent researchers who examined it reported that it verifies the existence of security features rather than their correct implementation: it can see that a policy is present and not that the policy grants everyone everything.
Where Lovable's built-in security scanner wins
It is free, it is already turned on, and it runs at exactly the right moment — before publish rather than after. Nothing on this page is an argument for turning it off, and if it is catching things for you then it is doing its job. Run it. This page is about what it does not look at.

Choose Lovable's built-in security scanner if
- You build on Lovable and want a check that costs nothing and needs no setup.
- You want the check to run at publish time, in the tool you are already in.
- You are early enough that the obvious misconfigurations are the whole risk.
Choose Sentris if
- You want a policy read for what it actually grants, not just confirmed to exist.
- You have moved off Lovable, or you build across several tools, and the check has to travel with the code.
- You want the deployed bundle fetched and read, not just the project inspected.
- You want to be told when something new appears, rather than only at publish time.
- You want the fix written out as SQL you can paste.
Questions
Lovable already scans my app. Why would I pay for another one?
Possibly you would not. If the built-in check is the only security anything you have and you are pre-launch, turning it on is the highest-value five seconds available to you, and a free scan here will tell you within a minute whether there is anything else to find. The gap researchers pointed at is a specific one: existence versus implementation. A table with a policy attached passes an existence check; a policy of using (true) attached to that table hands every row to every anonymous visitor, and that is what we look for.
Does it work if I move off Lovable?
No. It is a platform feature and it goes away with the platform. That is the usual reason people end up looking for something else — the code outlives the tool that generated it.
Is the criticism of it fair?
It is sourced to independent researchers rather than to us, and we would rather point at their work than characterise it further. The narrow version we are willing to state ourselves: a pre-publish check inside the generating platform is a good default and a poor ceiling.
One number nobody else on this list publishes
False-positive floods are the standing complaint about this whole category, and not one tool in it states its rate. Ours is precision 1.000, recall 1.000 over 24 planted findings in 9 repositories — with the date, the commit, the scoring rules and the command that reproduces it, plus a paragraph on why 9 repositories is a small corpus. Measured 2026-08-11.
