Reproduce a cross-tenant RLS leak and verify the fix
Supabase RLS Leak Demo is a focused, open-source testing tool designed for developers and founders working on multi-tenant applications. It provides a simple yet powerful fixture to simulate a cross-tenant Row-Level Security (RLS) leak in PostgreSQL, allowing users to verify whether their security policies are truly effective. By running a straightforward test suite with commands like 'npm ci && npm test', users can identify potential leaks and confirm their fixesβno need for Docker, cloud credentials, or production data. This makes it an excellent resource for teams committed to security and data integrity in multi-tenant SaaS platforms. The tool's unique value lies in its ability to demonstrate that a policy may appear correct but still harbor vulnerabilities, offering clear evidence before deploying to production.
Pros
- Simple setup with zero dependencies on Docker or cloud credentials
- Open-source and easy to run locally for immediate security testing
- Provides clear, reproducible evidence of security leaks and fixes
- Designed specifically for multi-tenant SaaS applications
- Helps teams validate security policies before deployment
Cons
- Limited to PostgreSQL and Supabase environments
- Primarily focused on RLS leak testing, not a comprehensive security suite
- Requires familiarity with SQL policies and testing practices
Best for
- β’ Testing and verifying multi-tenant data security policies
- β’ Demonstrating RLS vulnerabilities during security audits
- β’ Validating fixes for RLS leaks before production deployment
- β’ Educational tool for developers learning about RLS security
Pricing: Open source and free to use, with no costs involved. It is designed as a lightweight fixture for local testing and validation.

Multi-agent review catching bugs early in AI-generated code
Claude Code Review is an advanced AI-powered tool designed to enhance the quality and security of AI-generated code through multi-agent analysis. It dispatches a team of AI agents to scrutinize every pull request, identifying bugs, security vulnerabilities, and hidden logic flaws that might be overlooked by conventional reviews. This proactive approach ensures that code is thoroughly vetted before reaching production, reducing costly errors and improving overall reliability. Currently available in research preview for Team and Enterprise plans, Claude Code Review appeals to development teams seeking an intelligent, automated layer of code quality assurance. Its ability to verify findings helps minimize false positives, making feedback more actionable and trustworthy. By integrating this tool into their workflow, organizations can benefit from faster, more accurate code reviews, ultimately accelerating development cycles while maintaining high standards of security and performance.

- Multi-agent analysis provides comprehensive code review coverage
- Detects bugs, security issues, and hidden logic flaws effectively
- Reduces false positives through verification of findings
- Automates early bug detection, saving time in development
- Suitable for teams seeking AI-enhanced development workflows
Cons
- Currently in research preview, so may have limited availability or stability
- Primarily designed for AI-generated code, so less effective for human-written code
- Pricing details are not explicitly disclosed, possibly costly for small teams
Best for
- β’ Automated review of pull requests in AI-driven development projects
- β’ Early detection of security vulnerabilities in codebases
- β’ Reducing manual review workload for large development teams
