Playback
Video player built using electron and node.js
playback is another project by the same author, aimed at simplifying media playback of streaming sources in JavaScript/Node.js contexts. The goal of Playback is to act as a thin wrapper or abstraction layer that eases the task of launching and controlling a media player from code or CLI, perhaps integrating with torrent-based streaming (e.g. from peerflix) or other streaming sources. The library provides programmatic controls over launching playback, passing custom options or arguments, and managing process lifecycle — making it useful for scripts, automation, or tooling where you need to play media without manually wiring up system calls. Playback can be especially handy when building applications that need to fetch media dynamically (from network, torrent, or remote URL) and immediately play it, without requiring the user to manually download, open, and configure a media player themselves. -

RESTful API Node Server Boilerplate
A boilerplate for building production-ready RESTful APIs using Node.js
A boilerplate/starter project for quickly building RESTful APIs using Node.js, Express, and Mongoose. By running a single command, you will get a production-ready Node.js app installed and fully configured on your machine. The app comes with many built-in features, such as authentication using JWT, request validation, unit and integration tests, continuous integration, docker support, API documentation, pagination, etc. The app has a utility ApiError class to which you can attach a response code and a message, and then throw it from anywhere (catchAsync will catch it). Request data is validated using Joi. Check the documentation for more details on how to write Joi validation schemas. In production mode, only info, warn, and error logs will be printed to the console. It is up to the server (or process manager) to actually read them from the console and store them in log files. -

Ramme
Unofficial Instagram Desktop App
Unofficial Instagram Desktop App. The latest version of Ramme for macOS, Linux and Windows is available. macOS 10.9+, Windows 7+ & Linux are supported. Although technically it is possible to access Instagram from the desktop of the PC thanks to its web version , it is not the same as using the app. The design is not the same, the navigation is also different and in general it does not provide the same user experience as the mobile app. Ramme, (name whose meaning in Danish is " photo frame ") replicates the design of the mobile app in detail, in an agile and easy-to-use interface (because you already know it very well). Of course, do not expect extra functions or added options beyond the basic ones of the Instagram app itself. Precisely this simplicity and minimalism is one of its strengths. Ramme is a good alternative for those looking to have the same Instagram experience on desktop as on their mobile, and don't want to rely on a web page in the browser. -

Ruler AI
Centralize and sync AI coding rules across tools and projects
Ruler is a CLI tool that centralizes instructions for AI coding assistants in one place.

This reduces duplication, avoids inconsistent outputs, and keeps guidance aligned as projects evolve. Ruler supports nested rule loading, allowing teams to define context-specific instructions for different parts of a codebase. It also manages MCP server settings, automates .gitignore updates, and provides simple commands to initialize, apply, and revert configurations. Designed for teams using multiple AI agents, it improves workflow consistency, simplifies onboarding, and ensures all assistants follow the same standards across projects. -

SVGO
Node.js tool for optimizing SVG files
SVG Optimizer is a Node.js-based tool for optimizing SVG vector graphics files. SVG files, in particular those exported from multiple editors, normally contain tons of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result. Some options can be configured with CLI though it may be easier to have the configuration in a separate file. SVGO has a plugin-based architecture, so almost every optimization is a separate plugin. -

UIkit
Lightweight modular front-end framework for developing web interfaces
A lightweight and modular front-end framework for developing fast and powerful web interfaces. UIkit will work on pretty much any modern browser. Using UIkit works best if you have a solid code editor, for example Sublime Text or Atom. To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand. -
