blinkof.ai is an AI tester and product manager for the vibe-coding era — built for apps made with Lovable, Bolt, v0, Replit and Cursor. Paste your app's URL and Blinkof uses it the way a hostile first-time customer would: it signs up, clicks around, types adversarial input and tries to break things before your users do.

Every run produces a report a human can actually read — bugs, security holes and UX friction, with screenshots, ranked by what loses you users. And because every finding ships as a ready-made fix prompt, you repair issues by pasting them straight back into your builder.

No setup, test scripts or IDE — just paste a URL
Probes sign-ups, forms and security like a real user
Findings ranked by user impact, with screenshots
One-paste fix prompts for Lovable, Bolt, v0 & Cursor
