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. -

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). -

DigitalPlat FreeDomain
DigitalPlat FreeDomain: Free Domain For Everyone
FreeDomain is a DigitalPlat project that provides free domain names for individuals, developers, open-source projects, nonprofits, and small organizations. It is built around the idea that everyone should be able to create a public web identity without paying for a domain upfront. Users can register a domain and connect it to a DNS provider such as Cloudflare, FreeDNS, Hostry, or their own DNS infrastructure. The repository includes documentation for account setup, DNS configuration, and domain activation. It is intended to be approachable even for users with little prior DNS experience. FreeDomain is best suited for personal websites, small projects, testing environments, and public-interest web initiatives. -

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. -

Screenshot as a Service
Website screenshot service powered by node.js and phantomjs
Screenshot as a Service is an archived Node.js project that provides a simple website screenshot service powered by Express and PhantomJS. It exposes an HTTP server that can receive a URL, render the page through PhantomJS, and return or save a screenshot image. The project was designed as a lightweight service for automating visual captures of websites without manually opening a browser. It includes asynchronous usage examples for taking screenshots of multiple sites at regular intervals and saving them to disk. Because it relies on PhantomJS, it reflects an older generation of headless browser tooling and should not be treated as a modern screenshot stack. It remains useful as a reference for the basic architecture of screenshot APIs and automated web capture services. -

CF-Workers-SUB
Aggregates any of your nodes with multiple subscriptions
CF-Workers-SUB is a project that uses Cloudflare Workers to aggregate or convert multiple subscription sources (for proxy nodes/configs) into a personalized subscription link for the user. Essentially, it lets you input your own node(s) and then generate a unified subscription endpoint that others can use with tools like Clash, Sing-box, or V2Ray. The repository emphasizes being user-friendly for scenarios where one has many proxy/node links but wants to streamline into a single subscription feed. It also supports variable configuration (token, built-in nodes, custom add/CSV/API sources) to produce automated “preferred line” generation. The project is aimed at “subscription” style services (i.e., providing proxies as subscriptions) rather than pure application logic, and is tailored toward self-hosters. It’s designed for ease of deployment on Workers or Pages, enabling people to maintain their own subscription link infrastructure cheaply. -

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. -

Web Archives
Browser extension for viewing archived and cached versions of websites
Browser extension for viewing archived and cached versions of web pages, available for Chrome, Edge and Safari. Web Archives is a browser extension that enables you to find archived and cached versions of web pages, and comes with support for more than 10 search engines. Searches can be initiated from the context menu and the browser toolbar. A diverse set of archive and cache sources are supported, which can be toggled and reordered from the extension's options. Visit the wiki for the full list of supported search engines. You may choose to allow the extension to run on every website, or grant access to the current website before a search. When you grant access only to the current website, access must also be granted to each search engine in order to view search results. A handful of search modes are offered that serve different use cases. The search mode can be set independently for the context menu and the browser toolbar from the extension's options. -

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. -

CF-Workers-docker.io
Docker Warehouse Image Proxy Tool
CF-Workers-docker.io is a project by cmliu that sets up a proxy for Docker Hub (and potentially other container image registries) using Cloudflare Workers, effectively acting as a middle-man mirror to improve image pull reliability and speed in regions where direct access is degraded. The idea is to intercept registry requests, reroute or mirror them through a worker endpoint, and therefore bypass regional limitations or firewall blocks affecting official Docker registries. Users can deploy their own copy of this proxy, point their Docker daemon’s registry-mirrors configuration to it, and benefit from an accelerated and more accessible image pull experience. The project’s README warns about possible policy risks—since Cloudflare’s terms forbid use of Workers for VPN or similar proxy services, so users deploy at their own risk. It also includes instructions for setting up both Docker daemon and containerd/podman equivalents by customizing configuration files.
