New: SEO & AEO scanning — see how Google ranks you and how ChatGPT, Claude & Perplexity cite youSee how it works
Both scan vibe-coded apps for security issues from a URL. Vibe App Scanner sells one-time security audits ($9–19) and a $99/month continuous plan — security only. CheckVibe is an all-in-one subscription ($0 free, $24–59/month) that adds SEO + AEO scanning, uptime monitoring, an API, and an MCP server.
TL;DR
Vibe App Scanner (vibeappscanner.com) is one of the best-known security scanners for vibe-coded apps — it popularized the "89.5% of AI-built apps ship with vulnerabilities" framing and offers quick, affordable one-time audits. CheckVibe covers the same security ground on a subscription model and extends it to the rest of what a shipped app needs: search and AI-answer-engine visibility, uptime, performance, and email health.
