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, checked in August 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 Vendors change fast; if you spot something out of date, tell us at hello@xlogs.com.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) |
| 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 | 3 scans/day free | Config + deploy pipeline | Yes | On commit (paid) |
| Snyk | Yes | Free tier | Dependencies + source | Yes | 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.
Lovable built-in. Lovable now ships its own security checks including RLS policy linting, and offers a deeper agentic scan. If you build on Lovable, use it. xlogs is the outside-in second opinion.
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.
ZeriFlow. Strong on configuration and deploy-pipeline checks (cookies, DNSSEC, DKIM and more) that xlogs does not run. Free tier is 3 scans/day; paid around €9.99/month.
Snyk. A different job: dependency and source vulnerability scanning at depth. Complementary to a live scan, not a substitute.
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 (cookies, DNSSEC, DKIM) that xlogs does not. 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.
