Most security tools scan your code. Preflyt scans what actually matters - the live deployment. After you push to production, Preflyt checks your public URL for the security mistakes that slip through: .env files served publicly with database passwords, open Redis and Postgres ports, missing HSTS and CSP headers, exposed .git repositories, admin panels without protection, and debug endpoints left on. Run it from your browser at preflyt.dev or from your terminal with npx preflyt-check. Takes about 30 seconds, no signup needed. Every scan generates a shareable report with a unique link - send it to your team, post it on social media, or keep it as a record. Preflyt also works with AI coding agents. Drop a SKILL.md file in your project and agents like Cursor, Claude Code, GitHub Copilot, OpenClaw, and Cline automatically scan after every deploy. No CI/CD configuration needed. Built for indie developers, vibe coders, and small teams who ship fast and want a quick safety check before users find the problems first. Free for 3 scans. Pro at $9.99/month for unlimited scans and CLI access.

Preflyt.dev features and specs

  • File and Code Exposure Scanning
    Detects publicly accessible .env files, .git repositories, backup files, source maps, and sensitive configuration files.
  • Server and Network Security Scanning
    Checks for open database ports (MySQL, Postgres, Redis, MongoDB), exposed admin panels, debug endpoints, and dev server ports
  • HTTP Hardening Analysis
    Verifies security headers (HSTS, CSP, X-Frame-Options), CORS configuration, cookie security flags, and server version leakage.
  • Command Checker
    Paste any terminal command to detect typosquatted packages, hidden unicode characters, and piped downloads before you run them.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Preflyt.dev and Nullstack.

What makes your product unique?

Preflyt.dev's answer

Preflyt scans the live deployment, not the code. Most security tools analyze source code or dependencies. Preflyt checks what's actually exposed on the public internet - the same perspective an attacker has.

Why should a person choose your product over its competitors?

Preflyt.dev's answer

Zero friction. Paste a URL and scan instantly - no account, no setup, no agents on your server. Also works from the terminal with npx (no install) and with AI coding agents via a skill file. Most alternatives require signup, onboarding, or complex configuration

How would you describe the primary audience of your product?

Preflyt.dev's answer

Indie developers, solo founders, and small teams who ship fast and want a quick safety check before users find the problems. Especially relevant for developers using AI coding tools like Cursor and Claude Code who deploy frequently

What's the story behind your product?

Preflyt.dev's answer

Kept seeing the same deployment mistakes in live web apps - .env files with database passwords served publicly, open database ports, missing security headers. These aren't code bugs, they're deployment oversights. Built Preflyt to catch them in 30 seconds.

Who are some of the biggest customers of your product?

Preflyt.dev's answer

Preflyt is early stage with 80+ developers using it organically. Focused on indie developers and small teams right now
