xlogs vs Vibe App Scanner
Both xlogs and Vibe App Scanner scan a deployed AI-built app from its URL, read-only, and report security issues. They overlap a lot. Here is an honest look at where they differ and when each one fits. It comes from us, so read it knowing we make xlogs. Claims about Vibe App Scanner were checked against its own pages on 30 September and 6 October 2026.
See what xlogs finds on your app
What they share
Both are live scanners: you paste your app's URL and they check the deployed app the way a visitor could, without touching your source code. Both target people building with AI tools rather than security engineers. Both let you run a first scan free. The difference is what you see: Vibe App Scanner's free scan shows issue counts and one finding in detail, with the full report on a paid plan, while xlogs shows every finding and every fix free.
Where xlogs focuses
xlogs is built around the fix, not just the finding. Every issue comes with a plain-English explanation and a copy-paste instruction for your AI coding assistant (Lovable, Cursor, Claude Code), plus Verify: re-scan after you deploy and see whether the finding is still observed. It uses no AI at runtime: the same responses always produce the same findings. And it holds a strict line on false alarms: a finding is only marked critical when there is real evidence behind it.
It has also grown past the live scan since this page was first written. You can point it at a public GitHub repo for 35 supply-chain checks, read-only and never executed, covering install hooks, obfuscated code, credential access and prompt injection hidden in AI-instruction files. You can drop a server access log in and see which paths people are probing for, parsed in your browser with nothing uploaded. And you can hold both at once, which is the part nothing else here does: your log says what was requested, the scan says what you actually serve, and only together do they tell you someone asked for your environment file and found it.
Vibe App Scanner has been at this longer and does more around the scan: a much larger library of published security content, paid monitoring, checks beyond security such as SEO, performance and accessibility, and on its Pro plan a weekly deep scan that logs into your app and tries to reach other users' data. xlogs never logs in, by design, so that last one is a check we will not match. If breadth, monitoring or a logged-in test matters most to you, that is a real strength on their side.
| xlogs | Vibe App Scanner | |
|---|---|---|
| How you run it | Paste a URL, no signup | Paste a URL; first scan free, no card |
| What is free | Every finding and every fix, every scan | Issue counts and one finding in detail; the full report from 19 USD per month |
| What it scans | Your live, deployed app (read-only) | Your live, deployed app; Pro (39 USD per month) adds a weekly deep scan that logs into your app |
| The fix | Plain-English, copy-paste for your AI coding tool, with each finding | Copy-paste fix for your AI tool, on paid plans |
| Verify a fix | Rescan compares with the first scan and says whether each finding is still detected, included | Re-scan on demand on paid plans; weekly monitoring on Pro |
| Proof a table is readable | Column names and a row count, never your users' data | Sample data from the table |
| AI at runtime | None; deterministic and reproducible | Not stated |
| False-alarm posture | Severity must be earned; calm on low-confidence findings | Marks public Firebase and Supabase anon keys as likely informational |
| MCP server | Free: xlogs mcp | On Pro or their AppSumo deal |
| Content library | 60 published pages: per-platform hubs, per-vulnerability guides, questions, comparisons and tools | Over 1,100 pages in its sitemap |
| Repo scanning | 35 supply-chain checks on a public repo, read-only | Not stated |
| Access log analysis | Drop an access log: parsed in your browser, never uploaded | Not stated |
| Joins probes to exposure | Yes. Your log says what was requested, the scan says what you serve | Not stated |
Common questions
Is xlogs a Vibe App Scanner alternative?
Yes, for the core job: both scan a deployed AI-built app from its URL for issues like an open database, exposed keys, and missing protections. xlogs leans on a free fix-and-verify loop and honest severity; Vibe App Scanner has a larger content library, paid monitoring, and a logged-in deep scan on Pro. Try xlogs free above and compare on your own app.
Which should I use?
If you want a plain-English fix you can hand straight to your AI coding tool and then recheck, free, xlogs is built for exactly that. If you want the broadest library of security guides, built-in monitoring, or a logged-in test of whether one user can reach another's data, Vibe App Scanner is further along there. They are not mutually exclusive.
