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 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.

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.
