Lighthouse
Automated auditing, performance metrics, & best practices for the web
Lighthouse is an open-source, automated tool that analyzes and audits web apps and web pages in order to improve their quality. Lighthouse collects modern performance metrics and insights on developer best practices; auditing for performance, accessibility, SEO and more. After auditing it produces a report either in JSON or HTML. Included in the report is a reference doc that explains the importance of the audit and how to fix the problem areas, which you can use to improve the web app or web page. Lighthouse can be integrated directly into the Chrome DevTools with its own panel. To run it, you would simply have to select the Lighthouse panel and click on "Generate report". It can also be run from the command line, or as a Node module. -

axe-core
Accessibility engine for automated Web UI testing
Axe is an accessibility testing engine for websites and other HTML-based user interfaces. It's fast, secure, lightweight, and was built to seamlessly integrate with any existing test environment so you can automate accessibility testing alongside your regular functional testing. Axe-core has different types of rules, for WCAG 2.0 and 2.1 on level A and AA, as well as a number of best practices that help you identify common accessibility practices like ensuring every page has an h1 heading, and to help you avoid "gotchas" in ARIA like where an ARIA attribute you used will get ignored. With axe-core, you can find on average 57% of WCAG issues automatically. Additionally, axe-core will return elements as "incomplete" where axe-core could not be certain, and manual review is needed. -

eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user. -

Internet Pi
Raspberry Pi config for all things Internet
Internet Pi is an Ansible playbook and configuration framework for a Raspberry Pi (or similar single-board computer) that transforms it into a network-infrastructure monitoring and ad-blocking unit. The typical use case is: plug the Pi into your home network, install Pi-hole for DNS-level ad-blocking and privacy, and deploy Prometheus + Grafana to monitor internet connection quality, ping latency, speed tests, and uptime trends. The intention is both practical (reduce ads, manage DNS) and observational (track your internet link over time, identify drops, latency spikes, or service degradation). The project supports additional modules like monitoring smart plugs (e.g., Shelly), monitoring air quality (via AirGradient sensors), or monitoring Starlink statistics. By combining open-source monitoring, visualization, and infrastructure automation, it gives you a “set-and-watch” home network observability stack. -
