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.

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. -

Site Kit for WordPress
Site Kit is a one-stop solution for WordPress users
Site Kit is a first-party WordPress plugin that brings key Google services into a single dashboard so site owners can see how their content performs and fix issues without leaving wp-admin. After a guided setup and verification flow, it connects properties to Search Console, Analytics, AdSense, PageSpeed Insights, and other services, surfacing the most relevant metrics per page and per site. The plugin focuses on clarity: traffic sources, search queries, top pages, and monetization signals appear alongside actionable performance recommendations. It also handles authentication and permission scopes securely, so multiple collaborators can access insights without sharing credentials. Widgets and contextual panels put data where it’s needed—for example, on the post list or edit screen—reducing tab-switching. For developers and agencies, Site Kit simplifies client onboarding and standardizes reporting across many sites. -

WorkerVless2sub
Automate batch replacement to generate subscription generators
WorkerVless2sub is a dedicated subscription generator focused on providing “preferred line” subscriptions by processing VMess, VLESS, Trojan nodes, filtering and replacing automatically via a Cloudflare Worker script. The idea is you supply node lists (or use existing APIs/CSV sources) and the worker filters them by criteria like speed or reliability and then emits a subscription link for end-users. It supports deployment on Cloudflare Pages or Workers, offers configuration via variables like HOST, UUID, PATH, ADD, ADDAPI etc., and has an Apache-2.0 license. The tool supports both IPv4 and IPv6 node sources, speed test CSV inputs, and logic to drop nodes that don’t meet the threshold (DLS variable). It has a sizeable star count and forks indicating broader adoption in self-hosted proxy subscription communities. The README also explicitly warns about hosting personal private nodes in the script if intending public use. -

Fenix Web Server
A simple and visual static web server with collaboration features
Fenix is a desktop-based static web server application built for developers who want a quick, visual, and easy way to serve local folders as HTTP servers — useful for previewing static sites, mocking APIs, or sharing directories without requiring heavy web server setup. It provides a GUI that lets you point to a local directory, pick a port (or auto-choose an available port), and start a server with a single click; this makes it a handy tool for front-end developers, static-site creators, or anyone needing a fast local web server. Beyond just serving static files, Fenix supports features like automatic port management, optional GZip compression, optional JS/CSS minification, Markdown-to-HTML rendering, and simple server logging — making it more capable than the most minimal style tools. The app can also share your local site publicly (for example via tunnelling) — useful for quick demos, sharing prototypes, or collaborating with remote reviewers. -

Headless Chromium-based modular web performance metrics collector. Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance. -

A PHP script with maps of the World, China, Canada, USA, India, Africa and Europe that allows the user to select the countries, provinces or states by clicking on them or selecting a checkboxes. Selection causes the entity to turn a default color which contrasts with defaults colors of all bordering countries. Thus a patchwork is made to show the history of countries, states or provinces traveled. Added features allow users to download their maps, to blow them up to posters of any size printed with media of any standard size such as A4 or letter size paper; and to get permanent URLs of their made maps in order to come back and further annotate them at a later date.

AST explorer
A web tool to explore the ASTs generated by various parsers
Paste or drop code into the editor and inspect the generated AST. Depending on the parser settings, it not only supports ES5/CSS3. Since the future syntax is supported, the AST explorer is a useful tool for developers who want to create AST transforms. In fact, transformers are included so you can prototype your own plugins. Save and fork code snippets. Copy the URL to share them. Copying an AST or dropping a file containing an AST into the window will parse the AST and update the code using escodegen. Otherwise, the content of the text editor will be replaced with the content of the file (i.e. you can drag and drop JS files). Choose between multiple parsers and configure them. shift+click on a node expands the full subtree. Hovering over a node highlights the corresponding text in the source code. Editing the source or moving the cursor around will automatically highlight the corresponding AST node (or its ancestors of it isn't expanded). -
