Introduction
vibecheck is a specialized security scanner designed for AI-generated code, helping developers catch critical vulnerabilities before shipping applications. It provides a robust security layer for projects built rapidly with AI coding assistants like Cursor, Lovable, Bolt, v0, Replit, and Windsurf.
Target Audience & Use Case
This SaaS is primarily aimed at solo developers and small teams who leverage AI coding assistants to accelerate their development process. It addresses the unique security challenges that arise from "vibe coding," where functional code is prioritized over inherent security, often leading to common vulnerabilities.
Key Features
- Comprehensive Scanning: Integrates industry-standard tools like Gitleaks, Semgrep, njsscan, and 50 custom checks tailored for AI-generated code.
- AI-Powered Triage: Utilizes Claude AI to explain findings in plain language, prioritize vulnerabilities, and suggest actionable fixes, moving beyond raw scanner output.
- GitHub Integration: Connects directly to GitHub repositories to scan source code for secrets, unauthenticated routes, SQL injection, and many other issues.
- Live URL Checks: Offers instant header and TLS checks for live URLs without requiring an account.
- AI-Specific Vulnerability Detection: Specifically targets common security mistakes in AI-built apps, such as disabled Row Level Security (RLS), missing authentication, and secrets in source code or AI prompts.
- VS Code Extension: Available as a VS Code extension for scanning code directly within the development environment before deployment.
Use Cases
vibecheck is invaluable for developers who are rapidly building and deploying applications with AI assistance. For instance, a solo developer using Cursor to generate a Supabase-backed application can use vibecheck to automatically detect if Row Level Security (RLS) has been inadvertently disabled on critical tables, a common oversight in AI-generated code. This prevents data exposure that might otherwise go unnoticed until after deployment.
Another key scenario involves ensuring that sensitive API keys or tokens are not hardcoded into the codebase or exposed in public-facing client code, a frequent finding in AI-generated projects. By integrating with GitHub, vibecheck can scan for these secrets, as well as identify potential SQL injection points or unauthenticated API routes, providing a crucial security check before pushing changes to production. It's an essential tool for maintaining security hygiene in fast-paced, AI-driven development environments.
Pricing Information
vibecheck operates on a freemium model. The Free plan allows for 2 repositories with unlimited scans, providing vulnerability counts and titles. The Solo plan, priced at £12/month, supports up to 5 repositories and includes full explanations, suggested fixes, scan history, and diffing. For unlimited repositories and priority queue access, the Indie Stack plan is available at £27/month, also offering auto-PR for safe fixes. Pricing is per portfolio, not per seat.
User Experience and Support
The user experience is streamlined, offering both a web interface for GitHub integration and a VS Code extension for in-editor scanning. A standout feature is the Claude AI triage, which translates complex security findings into clear, human-readable explanations and prioritized fixes, making security accessible even for developers without deep security expertise. This eliminates the guesswork often associated with raw scanner outputs. The platform emphasizes ease of use, allowing developers to quickly identify and address vulnerabilities.
Technical Details
vibecheck leverages a powerful combination of static analysis tools: Gitleaks for secret detection, Semgrep for OWASP Top 10 patterns, njsscan for Node.js-specific vulnerabilities, and 50 custom checks tailored for AI-generated app patterns. Claude AI then processes the normalized results from these tools to provide intelligent explanations and prioritization. The scanning process involves a shallow clone of the repository in an isolated worker, with GitHub tokens AES-256-GCM encrypted at rest, ensuring code privacy and security.
Pros
- Specifically designed to catch vulnerabilities common in AI-generated code.
- Bundles multiple powerful security scanners into one easy-to-use platform.
- Claude AI provides clear, human-like explanations and prioritized fixes.
- Offers both GitHub integration and a VS Code extension for flexible scanning.
- Includes live URL checks for immediate feedback on deployed applications.
- Transparent pricing model with a generous free tier.
Cons
- Focuses primarily on AI-generated code, which might imply less emphasis on traditional codebases (though still effective).
- While Claude explains fixes, implementing them still requires developer effort.
- No explicit mention of support channels beyond the AI explanations.
- The `njsscan` tool implies a strong focus on Node.js, potentially less comprehensive for other languages.
Conclusion
vibecheck is an indispensable security scanner for developers embracing AI coding assistants, providing a crucial safety net for rapidly developed applications. By combining robust static analysis with intelligent AI-powered explanations, it empowers builders to ship secure products faster.
