UNPWNED is a passive web security scanner that runs 700+ automated checks against websites and GitHub repositories in under two minutes. It detects misconfigurations, leaked API keys and secrets, weak HTTP security headers, SSL/TLS issues, DNS and email auth gaps (DNSSEC, SPF, DKIM, DMARC), exposed config files (.env, credentials.json, SSH keys), Supabase and Firebase RLS problems, open API routes, dependency vulnerabilities, and more.

Every finding comes back in plain English with a copy-paste AI Fix Prompt that developers can paste into Cursor, Claude, ChatGPT, GitHub Copilot, Lovable, Bolt, Replit, v0, or any other AI coding agent โ€” turning security findings into one-shot fixes.

Built for: indie hackers, vibe coders, AI-builders, SaaS founders, and small teams shipping fast on Cursor / Lovable / Bolt / Replit / v0 / Base44.

Not a pentest replacement. UNPWNED is automated and passive (Deep Scan with active probing requires domain ownership verification). It is best used as a pre-launch and post-deploy hygiene check, plus continuous monitoring on Pro plans.

Pricing: Free plan includes 5 scans/month. Pro plans start at $9/mo and add unlimited fix prompts, PDF reports, scan history, GitHub repo monitoring with auto-issue creation, continuous monitoring with CVE alerts, and priority support.

The UNPWNED CLI (npm install -g unpwned) is open-source on GitHub. The hosted scanner platform itself is a closed-source SaaS.

UNPWNED features and specs

  • Data Breach Monitoring
    UNPWNED offers monitoring services to alert users if their personal information, such as email addresses or passwords, appears in known data breaches, helping them take timely action to secure their accounts.
  • User-Friendly Interface
    The platform is designed with simplicity in mind, making it accessible for users of varying technical expertise to check their exposure and understand security recommendations.
  • Proactive Security Alerts
    Users receive notifications when new breaches are detected involving their information, allowing for proactive password changes and security measures rather than reactive responses after damage occurs.
  • Privacy-Focused Approach
    The service emphasizes protecting user privacy in how it handles and checks personal data against breach databases, which can appeal to privacy-conscious individuals.
  • Educational Resources
    UNPWNED may provide guidance and resources on best practices for online security, helping users improve their overall digital hygiene beyond just breach detection.

Possible disadvantages of UNPWNED

  • Limited Brand Recognition
    Compared to more established breach-checking services like Have I Been Pwned, UNPWNED may have less name recognition, which could make some users hesitant to trust it with sensitive information.
  • Database Coverage Uncertainty
    It may be unclear how comprehensive or frequently updated UNPWNED's breach database is compared to larger, more established competitors, potentially leading to missed breach detections.
  • Potential Cost Barriers
    If the service requires a subscription or one-time payment for full features, this could be a barrier for users who prefer free alternatives already available in the market.
  • Dependency on Third-Party Trust
    Users must trust UNPWNED with potentially sensitive personal information to check for breaches, which requires confidence in the company's own security and data handling practices.
  • Limited Independent Reviews
    As a potentially newer or less mainstream service, there may be fewer independent reviews, security audits, or third-party validations available to verify the platform's effectiveness and reliability.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of UNPWNED

Overall verdict

  • UNPWNED appears to be a data breach monitoring and credential exposure checking service, though as a lesser-known player in this space, thorough independent research and verification of its security practices are recommended before entrusting it with sensitive information.

Why this product is good

  • Aims to help users check if their credentials have been exposed in data breaches
  • May offer monitoring services to alert users of new breaches
  • Focused on cybersecurity awareness and personal data protection

Recommended for

  • Individuals wanting to check personal data breach exposure
  • Users seeking basic credential monitoring services
  • Privacy-conscious users looking for alternative breach-checking tools beyond mainstream options
  • Those who conduct additional due diligence before relying on lesser-known security services

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment
