eslint-plugin-jsx-a11y vs NetsCLI

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.

NetsCLI is an open-source network scanner for discovering LAN devices, scanning TCP and UDP ports, querying DNS, and inspecting hosts. It runs on Linux, macOS, and Windows, with a desktop app, terminal UI, command-line interface, and MCP server built on one Rust core. The desktop app supports multiple investigation tabs, sortable and filterable results, exports, and scan history. Discovery can add reverse DNS, ARP cache details, MAC addresses, and device makers when the operating system has that information. Network operations in the CLI support JSON and YAML output; list commands also support CSV and Markdown. The MCP server runs over stdio and exposes structured network tools to compatible AI clients, including Claude Code and Cursor. NetsCLI is MIT-licensed and free for personal, open-source, and commercial use. Its binaries and installers are said to be checksummed and signed with Sigstore cosign. Packet capture requires separate downloads and libpcap on Linux or macOS, or Npcap on Windows. It does not provide remote administration and lacks advanced service detection, NSE scripts, and OS fingerprinting.
