FixVibe scans AI-generated and fast-shipped web apps for the security mistakes that slip through when you're moving quickly. Paste your URL and it checks for exposed API keys and secrets baked into your bundle, misconfigured Supabase or Firebase settings, missing Row Level Security (RLS) policies, public file leaks, and weak or absent HTTP security headers. It's built around the failure modes that are most common in vibe-coded or prototype-turned-production apps — the kind of issues AI coding assistants introduce when security isn't part of the prompt. The tool is designed as a pre-launch preflight, not a full penetration test: it surfaces the obvious, high-impact problems fast, so solo developers and indie founders can ship with less exposure. Works without installing anything.
