Advanced Port Scanner vs eslint-plugin-jsx-a11y

Advanced Port Scanner is a free Windows desktop utility for finding open network ports and identifying software versions reachable through them. It scans TCP and UDP ports across an IP address range and lets you specify which ports to check. Multi-threaded scanning is available, while a high-accuracy mode checks each computer repeatedly at a slower pace. For LAN administration, the program provides Wake-On-LAN, remote shutdown, and commands that can run on remote computers. Discovered systems can be opened through HTTP, HTTPS, FTP, Telnet, SSH, RDP, or Radmin, with configurable clients for some protocols. Computer lists can be exported to XML, HTML, or CSV, and favorites can be loaded from XML. Radmin connections require Radmin Viewer. Famatech describes the tool for LAN and networking work, and says shutdown actions require authorization. It is distributed as a Windows executable installer and costs nothing.

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.
