    Tabulator

    Tabulator

    Interactive tables and data grids for JavaScript

    Tabulator allows you to create interactive tables in seconds from any HTML Table, Javascript Array or JSON formatted data. Simply include the library and the css in your project and you're away! Tabulator has an enormous number of features to help customize your table experience to your needs. With new features released every month, there is bound to be something to get your interactive table juices flowing. Tabulator is built to work with all the major front-end JavaScript frameworks including React, Angular and Vue. 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.

    Lighthouse

    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.

    jsdom

    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.

    CF-Workers-SUB

    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.

    WorkerVless2sub

    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.

    AST explorer

    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: 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.
