Best security scanners for AI-built apps
Most roundups in this space are written by one of the vendors and never say how they judged anyone. This one states its criteria first, sources every claim, and points out where xlogs loses. We make xlogs, so treat our entry with the skepticism you would treat any vendor writing about itself.
Our criteria, stated up front
We compared each tool on five things a person building with AI actually cares about:
- Account required? Can you get a result without signing up.
- Are findings free? Or is the finding, or its fix, behind a paywall.
- What layer? A live URL scan, a repository scan, or both. They catch different things.
- Read-only? Whether it only reads, or also writes and needs deeper access.
- Recurring model. How ongoing monitoring works, since that is what most tools charge for.
How we verified this
Every claim below was read from each tool's own public pricing and documentation pages, linked under each entry and last checked on 6 October 2026, not from a controlled head-to-head test. We did not run each scanner against a shared set of vulnerable apps, so this is a transparency-of-criteria comparison, not a benchmark, and we will not pretend otherwise. Where a detail was not stated on a vendor's own pages, the cell says so rather than guessing. Vendors change fast; if you spot something out of date, tell us at hello@xlogs.com.
The comparison
| Tool | Account | Findings free | Layer | Read-only | Recurring |
|---|---|---|---|---|---|
| xlogs (this site) | No | Yes, all | Live URL | Yes | Watch (paid, in beta) |
| Vibe App Scanner | Not stated | Counts + 1 finding; full report from $19/month | Live URL (+ logged-in deep scan on Pro) | Yes (deep scan: not stated) | Weekly monitoring (Pro, $39/month) |
| Lovable built-in | Yes (Lovable) | Included | Repo + platform | Mixed | On publish |
| Aikido | Yes | Free tier limited | Repo + cloud + domain | Mostly | Rescan every 3 days (free) |
| ZeriFlow | Yes (Google or GitHub) | 1 quick scan/day free | Config + deploy pipeline | Mostly | Scheduled rescans (paid) |
| Snyk | Yes | Free tier | Dependencies + source | Mostly | Continuous |
xlogs (this site). Ours. Read-only live scan, every finding and fix free, no signup. Does not read your repo, so source-only bugs and dependency CVEs are out of scope. Source: our methodology.
Vibe App Scanner. The closest to xlogs: a URL-in scanner for AI-built apps, with a much larger content library, monitoring, and on Pro a weekly deep scan that logs into your app and tries to reach other users' data, which xlogs never attempts. The free scan shows issue counts and one finding in detail; the full report and fixes are on paid plans. Sources: vibeappscanner.com, Vibe App Scanner pricing, its monitoring page, checked 6 October 2026.
Lovable built-in. Lovable now ships its own security scans: a Quick scan of database access rules and dependencies on every publish, and a Deep scan of your code. If you build on Lovable, use it. xlogs is the outside-in second opinion. Source: Lovable security docs, checked 6 October 2026.
Aikido. The honest answer for a team with a codebase: SAST, dependencies, cloud, containers. Free tier caps at 10 repos, 1 domain, 10 AutoFixes/month; paid starts around $300/month. Source: Aikido pricing, checked 6 October 2026.
ZeriFlow. Strong on configuration checks (the TLS certificate, DNSSEC, DKIM and more) that xlogs does not run, and a paid Advanced Scan reads your repository. Paid plans can open fix pull requests. Free tier is 1 quick scan a day after signing in; paid from $9.99/month. Sources: zeriflow.com, ZeriFlow pricing, checked 6 October 2026.
Snyk. A different job: dependency and source vulnerability scanning at depth. It opens fix pull requests automatically on repos you import. Complementary to a live scan, not a substitute. Sources: Snyk plans, Snyk fix pull requests, checked 6 October 2026.
Where xlogs loses
If you have a codebase and a team, Aikido or Snyk will catch things xlogs structurally cannot, because they read your source and dependencies and xlogs only sees the deployed site. If you build on Lovable, its built-in checks already lint your RLS policies from inside the project. ZeriFlow runs configuration checks (the TLS certificate, DNSSEC, DKIM) that xlogs does not. Vibe App Scanner's Pro plan logs into your app to check whether one user can reach another's data, which xlogs, by design, never does. xlogs is the fastest way to answer "is my live app leaking something right now" with no account and no cost, and it is deliberately not trying to be a full application-security platform.
