eslint-plugin-jsx-a11y vs Sherlock Forensics Port Scanner

eslint-plugin-jsx-a11y is a free MIT-licensed package that uses ESLint to statically inspect JSX for accessibility issues in React applications. Its rules cover alternative text, ARIA properties, values, roles and requirements, labels, keyboard access, and captions for audio and video. It can flag clickable non-interactive elements without keyboard listeners and interactive handlers on elements that are not focusable. Recommended and strict configurations are documented for legacy .eslintrc files and flat eslint.config.js files. Configuration can map custom component names to DOM element types and DOM attributes to JSX properties, allowing those abstractions to be checked. An optional polymorphicPropName setting is supported, although the project warns that polymorphic components can be harder to maintain. Installation instructions cover npm and Yarn and require ESLint. The plugin analyzes static code rather than rendered DOM. Its maintainers recommend pairing it with @axe-core/react and assistive-technology testing. It has no manual review tools, mobile testing, browser extension, or remediation guidance. The repository links to Tidelift for professional support.

Sherlock Forensics Port Scanner is a free desktop GUI tool for identifying exposed TCP ports and the services behind them. It scans the top 1,000 TCP ports by default, accepts custom port and CIDR ranges, and can scan all 65,535 TCP ports. For open ports, it retrieves service banners to identify software and version strings. Scans use TCP connect with the full three-way handshake; SYN scans are not supported. Results export to CSV with timestamps, target host, port, protocol, state and service identification. Each export includes an Ed25519-signed sidecar with the CSV’s SHA-256, signature, per-installation public key and UTC timestamp. The scanner identifies ports and services but does not check results against CVE databases or attempt exploitation. It runs on Windows and Linux. Version 0.1.7 supports 64-bit Windows 10/11 as a single executable without installation dependencies or elevated privileges; the native Linux x64 binary requires libgtk-3, libfontconfig1 and libxkbcommon. The free plan has no trial period, feature restrictions or expiry.
