eslint-plugin-jsx-a11y vs RustScan

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.

RustScan is a free command-line port scanner for finding open network ports. The project says it can scan all 65,000 ports in three seconds, and discovered ports can be passed automatically to Nmap for further analysis. It supports IPv6, CIDR ranges and file input, with scripting in Python, Lua and Shell. Listed capabilities include service detection, operating-system detection and greppable-text output. RustScan describes adaptive learning that uses information about the scan environment and usage to improve over time. The project also says its continuous integration checks whether the scanner becomes significantly slower than the previous version and aims to ensure accessibility. Cargo is the only officially supported installation method, although releases and package-manager options are also listed. The installation guide recommends Docker and says its image works across systems, including Windows, which is not officially supported. The maintainer says RustScan has been tested only on Linux and that macOS or Windows may have issues; the guide also notes macOS's low open-file limit can significantly affect scanning. The project is licensed under GPL-3.0.
