eslint-plugin-jsx-a11y vs Pentest-Tools 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.

Pentest-Tools Port Scanner is a cloud-hosted Nmap scanner for discovering open TCP and UDP ports and services on network targets. Users can scan a domain, one IP address, or a network range, including bulk IP ranges. Light scans cover the top 100 TCP and UDP ports; deep scans can extend to all 65,535 ports. Options include service-version and operating-system detection, TCP SYN, full TCP connect, and UDP scanning. Findings can be exported in CSV, JSON, or PDF. The product describes scheduled and parallel scans, notifications, API access, and scan-template workflows, with integrations including Jira, Slack, Microsoft Teams, webhooks, Burp Suite, and GitHub Actions. Internal targets require the VPN Agent, and internal network scanning is an optional add-on. A free plan is listed, but its tier limits are unspecified. Paid plans start at $95 a month, with pricing varying by asset count and billing cycle. The full scanner has a seven-day trial requiring a business email and card; cancel before day eight to pay nothing.
