Security Scanner for AI-Built (Vibe-Coded) Apps

Find security issues AI agents miss

In plain English

Apps written quickly by AI helpers can hide security problems those helpers never notice. CheckVibe looks for those weak spots so a builder can see them before a real user does. Builders pay a plan that can change with use, or a set of tiers, because a missed hole is worse than a careful extra look. The AI does most of the checking and the payments. The person running CheckVibe still checks quality, writes clear instructions, helps users, and treats risky findings with extra care.
