Vibe App Scanner Reviews

Disclaimer: I'm a paid product tester for AppSumo and received this tool for free to provide a detailed review. My opinions are entirely my own, and my compensation is not tied to the rating or taco score I give.

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.

I wouldn't trust the scan reports 100% at the current state. For instance there were a few misleading properties shown in the report generated:
- Stack: Next.js · Vercel · Cloudflare
- Embed Services Detected: Your app embeds YouTube. Configure frame-src to allow these services.

I don't actually use Vercel - my app is built with Next.js but is Dockerized and deployed without any connection to Vercel.

My app does link to YouTube Music but doesn't embed anything from YouTube, all media shown in my app are locally hosted and if I followed the suggestion blindly, it will just be an unnecessary open attack surface.

Some minor feedback - I think the UI/UX could be improved, it looks a bit simplistic and some sections like the "Passed checks" are hard to read because they're just walls of text.

Other than those minor issues I think it's a good tool to have.

Reached out to Jacob to ask a few pre-sale questions and he gave me really detailed answers that were specific to my situation, not just form responses. He clearly has a lot of experience in this space and cares about this project. In 7 years of buying appsumo products, one thing I've learned is that whether a product will succeed long-term has a lot more to do with the founder and team than with the tool itself.

As far as the product goes, it's simple but not in a bad way. You log in, run a scan, and it gives you an exportable report that can be directly pasted into Claude. I really appreciate that it runs checks for SEO, Accessibility, and Compliance. I wouldn't have even thought to check whether the visible labels above my form fields were attached to the fields themselves, but VAS caught that they weren't and gave me the exact prompt to fix it.

So far I'm very happy with my purchase. If you're thinking about it, give it a try for sure.
