middleBrick

API Security Risk Scoring Platform

middleBrick scans any API endpoint and returns a security risk score (A+ through F) with actionable findings โ€” no agents, no config, no credentials required.

How it works

Submit a URL or OpenAPI spec. middleBrick runs 12+ security checks in parallel and delivers a prioritized report with severity ratings and remediation guidance in under 60 seconds. It tests what an unauthenticated attacker would see โ€” black-box, zero setup.

AI & LLM API Security

The only self-service scanner with dedicated LLM checks: * System prompt leakage detection * Prompt injection testing * Jailbreak probes * Data exfiltration vectors * Excessive agency and cost exploitation

What it covers

OWASP API Security Top 10: * Access Control: BOLA/IDOR and BFLA. * Authentication: Multi-method bypass detection and JWT analysis. * Data Exposure: PII, API keys, and credit cards with Luhn validation. * Technical Vulnerabilities: Input Validation, Rate Limiting, SSRF, and Security Misconfiguration. * Modern Architecture: GraphQL vulnerabilities, Encryption & Transport Security, and API Inventory gaps. * Specifications: Full OpenAPI 2.0/3.0/3.1 spec analysis included.

Built for your workflow

  • Dashboard: Scan, track scores, and export PDF compliance reports (SOC 2, PCI-DSS, HIPAA, ISO 27001).
  • CLI: npx middlebrick scan in your terminal or CI pipeline.
  • GitHub Action: Fail builds when security score drops below threshold.
  • MCP Server: Scan from Claude, Cursor, or any MCP-compatible AI tool.

KnowCSS features and specs

  • Interactive CSS Learning
    KnowCSS provides an interactive way to learn and practice CSS properties and concepts, making it easier for beginners to understand how CSS works through hands-on experimentation.
  • Quick Reference Tool
    The site serves as a handy quick-reference tool for CSS properties, allowing developers to quickly look up syntax, values, and usage examples without digging through lengthy documentation.
  • Visual Demonstrations
    KnowCSS offers visual demonstrations of CSS properties, helping users see the immediate effect of different CSS values, which accelerates understanding of styling concepts.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

Analysis of KnowCSS

Overall verdict

  • KnowCSS is a lightweight, no-frills CSS framework that helps developers quickly style HTML documents without writing custom CSS or dealing with class-heavy frameworks, making it a decent choice for simple, semantic styling needs, though it lacks the extensive ecosystem, community support, and advanced features of more established frameworks like Bootstrap or Tailwind CSS.

Why this product is good

  • Provides classless or minimal-class styling that works directly on semantic HTML elements
  • Lightweight footprint reduces page load times compared to bulkier frameworks
  • Simple to integrate for quick prototypes or small projects without a steep learning curve
  • Encourages clean, semantic HTML markup rather than div-heavy class-based structures

Recommended for

  • Developers building small to medium-sized websites who want quick styling without writing custom CSS
  • Beginners learning HTML/CSS who want to see immediate visual results with minimal setup
  • Projects prioritizing semantic HTML and minimal class usage
  • Quick prototypes, documentation sites, or internal tools where extensive customization isn't required

Analysis of middleBrick

Overall verdict

  • I don't have verified information about middleBrick (middlebrick.com) in my training data, so I can't confirm details about its offerings, reputation, or quality. I'd recommend checking independent review sites, verifying business registration, reading recent customer feedback, and confirming security/legitimacy indicators (SSL, contact info, reviews on Trustpilot or BBB) before using the service.

Why this product is good

  • No verified data available about this specific domain to confirm legitimacy or quality
  • Unable to assess without independent, up-to-date research from trusted review sources
  • Recommend checking Trustpilot, BBB, or similar consumer protection sites
  • Verify company registration, physical address, and customer service responsiveness

Recommended for

  • Anyone considering this site should conduct independent due diligence first
  • Not recommended to rely solely on AI-generated claims for unfamiliar or niche websites
  • Best suited for users who verify through multiple independent, current sources before purchasing
