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.

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. -

iii
Effortlessly compose, extend, and observe every service
iii is a backend unification engine that organizes application behavior around a small set of primitives such as functions, triggers, and workers. It is designed to connect existing backend systems into a more inspectable and programmable runtime. The project includes a console for developers and operators to inspect functions, triggers, traces, and live state. Its goal is to reduce backend sprawl by giving teams a single operational layer for event-driven and function-based workflows. iii appears especially useful for teams that want clearer visibility into distributed backend behavior without replacing every existing component. Its main value is combining orchestration, observability, and operational control into a compact backend engine. -

Java JWT
Java implementation of JSON Web Token (JWT)
A Java implementation of JSON Web Token (JWT) - RFC 7519. This library requires Java 8 or higher. The last version that supported Java 7 was 3.11.0. The library implements JWT Verification and Signing using several algorithms. The Algorithm defines how a token is signed and verified. It can be instantiated with the raw value of the secret in the case of HMAC algorithms, or the key pairs or KeyProvider in the case of RSA and ECDSA algorithms. Once created, the instance is reusable for token signing and verification operations. When using RSA or ECDSA algorithms and you just need to sign JWTs you can avoid specifying a Public Key by passing a null value. The same can be done with the Private Key when you just need to verify JWTs. -

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. -

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. -

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. -

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. -
