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. -

Nomulus
Top-level domain name registry service on Google Cloud Platform
Nomulus is a production-grade, open-source domain registry platform used to operate top-level domains (TLDs). It implements the core registry protocols—EPP for registrar interactions, WHOIS/RDAP for public data access—and manages the lifecycle of domain objects, hosts, and contacts. The system is built to scale and to enforce policy: pricing rules, reserved names, premium tiers, grace periods, and automated renewals are modeled explicitly. It integrates with DNS provisioning, data escrow, and billing so you can run a compliant registry end-to-end rather than stitching together separate services. Operators get admin tools for reporting, manual adjustments, and policy configuration, while registrars interact through standards-compliant channels. Nomulus treats registries as serious infrastructure: audited flows, durable storage, and clear extension points for custom policies and TLD-specific behavior. -

Header filters and programmatic filters can be set independently allowing you to use a header filter to further restrict the rows shown in an already filtered data set. If an input element is used as the filter element, the table will be filtered in real-time as the user types in the input element. To prevent excessive redrawing of the table Tabulator will wait 300 milliseconds after the user has finished typing before triggering the filter. -

jsdom
JavaScript implementation of various web standards, for use with Node
jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern. -

Bedrock
WordPress boilerplate with modern development tools
WordPress boilerplate with modern development tools, easier configuration, and an improved folder structure. Bedrock is an open source project and completely free to use. Bedrock is a modern WordPress stack that helps you get started with the best development tools and project structure. Much of the philosophy behind Bedrock is inspired by the Twelve-Factor App methodology including the WordPress specific version. Bedrock is multisite network compatible, but needs the roots/multisite-url-fixer mu-plugin on subdomain installs to make sure admin URLs function properly. This plugin is not needed on subdirectory installs but will work well with them. Composer is used to manage dependencies. Bedrock considers any 3rd party library as a dependency including WordPress itself and any plugins. -

Jupyter Enterprise Gateway
Enables Jupyter Notebooks to share resources across clusters
Jupyter Enterprise Gateway is a headless web server with a pluggable framework for anyone supporting multiple notebook users in a managed-cluster environment. Some of the core functionality it provides is better optimization of compute resources, improved multi-user support, and more granular security for your Jupyter notebook environment - making it suitable for enterprise, scientific, and academic implementations. From a technical perspective, Jupyter Enterprise Gateway is a web server that enables the ability to launch kernels on behalf of remote notebooks. This leads to better resource management, as the web server is no longer the single location for kernel activity. It essentially exposes a Kernel as a Service model. By default, the Jupyter framework runs kernels locally - potentially exhausting the server of resources. By leveraging the functionality of the underlying resource management applications like Hadoop YARN, Kubernetes, and others. -

NewsBlur
NewsBlur is a personal news reader that brings people together

The backend crawls and parses feeds at scale, stores stories, and pushes updates to users in near real time, while the web app and mobile apps provide rich reading experiences. Its hallmark is “training”: you can tell the system what you like or dislike—authors, keywords, tags—and it prioritizes stories accordingly, surfacing what matters most. Features like saved stories, tagging, full-text search, and offline reading make it practical for heavy information consumers. Social elements allow sharing to your own “blurblog,” following friends, and discovering curated content, which turns a solitary reader into a lightweight network. Architecturally, it demonstrates a production-ready aggregation pipeline, a multi-tenant web app, and cross-platform clients living in one coherent codebase. -
