1. Vibe App Scanner
Security for Apps Built with AI
Vibe App Scanner is an external security scanner designed to detect vulnerabilities in apps built with AI. Its non-aggressive, but provides thorough crawling and fingerprinting of your web app to identify weaknesses. This includes areas like database and authentication security, exposed api endpoints and much more. Simply enter your app URL and an automated scan will run. All scans are then manually reviewed by a security professional. All findings will be displayed in your dashboard with evidence and remediation guidance.
2. RedVeil
Penetration Testing Powered Entirely by AI
Traditional pentesting is too slow for modern engineering. Waiting weeks for a consultant and paying tens of thousands for a single "point-in-time" snapshot doesn't work when you deploy code daily. RedVeil offers a new standard: the reasoning of a human hacker with the speed of software. Spin up a full, autonomous, AI driven penetration test in minutes and get an actionable audit-ready report by the afternoon. Why RedVeil? Speed & Price: Traditional pentests take weeks. RedVeil takes hours at a fraction of the cost. One-Click Retesting lets you remediate at your speed.

5. Safety Checkpoint
Safety check-ins that alert your people when you can't
CheckPoint is an automated emergency communication system. Set a check-in deadline, attach encrypted files, messages, vocal messages, and credentials to an emergency package, and choose who gets alerted if you miss it. Alerts are sent via email, SMS, and WhatsApp (soon). Built for solo travelers, night workers, protesters, families, and anyone in high-risk situations. Unlike GPS tracking apps, CheckPoint is privacy-first: no location sharing, no surveillance. Just proactive check-ins with end-to-end encrypted context.
6. Cutline
Cutline is a technical product manager that helps vibecoders
Building Cutline. We’ve identified a 'Vibecoding Cliff' where AI coding agents start to fail as production constraints (security, stability, latency) increase. Cutline is a technical product manager that helps vibecoders build with security, stability, and scalability from the start. Cutline helps you survive the MVP cliff by dynamically injecting security, stability, and scalability requirements into your coding agent, avoiding 'vibecoding whack-a-mole' sessions where the coding agent drops a previous requirement to satisfy the new one.
7. Feedbugs
