One of the problems with vibe coding is that you can get an app working long before you know whether it is safe to put in front of users.

Vibe App Scanner gives you a way to check the app you have deployed by entering its URL. It runs more than 150 checks, including exposed API keys, authentication issues, database permissions, and other security problems that can easily go unnoticed when you're focused on getting the app working.

What I particularly like is how it handles the findings. Each issue comes with an explanation, supporting evidence, and suggested fixes you can give to your AI coding tool. You can take those instructions back to Lovable, Cursor, Claude Code, or your developer, make the changes, and scan again to check the results.

For someone developing software with AI, I can see this becoming part of the development process. You make changes to your app, deploy them, run a scan, and address anything new that comes up. It also supports MCP, so you can connect it to your AI coding tools without having to manually copy everything between applications.

In my test, the scanning and suggested fixes worked well. I initially flagged a couple of things that would make the product more useful, particularly PDF reports for sharing findings with clients and a REST API for connecting scans and reports to other tools. The team added both, and I confirmed they were available in my retest.

I would still want a proper security review for an application handling sensitive data, but Vibe App Scanner gives founders and developers a way to catch common issues during development and after deployment.

Overall, I like the direction of this product, particularly for people using AI to develop software who may not have a security background. The ability to scan a deployed app, get specific instructions for addressing the findings, and check the results after making changes is what makes Vibe App Scanner worth considering.
