HLS.js
HLS.js is a JavaScript library that plays HLS in browsers
HLS.js is a JavaScript library that implements an HTTP Live Streaming client. It relies on HTML5 video and MediaSource Extensions for playback. It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a Web Worker when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016. HLS.js works directly on top of a standard HTML<video> element. HLS.js is written in ECMAScript6 (*.js) and TypeScript (*.ts) (strongly typed superset of ES6), and transpiled in ECMAScript5 using Babel and the TypeScript compiler. Webpack is used to build the distro bundle and serve the local development environment. -

Render Farm Deployment Kit on AWS (RFDK)
Library for use with the AWS Cloud Development Kit
The Render Farm Deployment Kit on AWS (RFDK) is an open-source software development kit (SDK) that can be used to deploy, configure, and manage your render farm infrastructure in the cloud. It offers high-level object-oriented abstractions to define render farm infrastructure using the power of Python and Typescript. The Render Farm Deployment Kit (RFDK) on AWS is an open-source software development kit that can be used to deploy, configure, and manage your render farm infrastructure in the cloud. The RFDK is built to operate with the AWS Cloud Development Kit (CDK) and provides a library of classes, called constructs, that each deploy and configure a component of your cloud-based render farm. The current version of the RFDK supports render farms built using AWS Thinkbox Deadline render management software, and provides the ability for you to easily go from nothing to a production-ready render farm in the cloud. -

OmniTools
Self-hosted collection of powerful web-based tools for everyday tasks
OmniTools is a self-hosted web application that bundles a large collection of everyday utilities into a single clean interface you can run on your own infrastructure. It’s designed to replace the random assortment of “free online tools” people use for quick tasks, while avoiding ads, tracking, and the need to upload sensitive files to unknown servers. A key design choice is that file processing happens entirely on the client side, meaning your data stays in your browser instead of being sent to the backend. The tool catalog spans both technical and non-technical needs, including image, video, audio, PDF, text, date/time, math, and data format utilities like JSON/CSV/XML helpers. It’s also packaged for straightforward self-hosting, with a lightweight Docker image and simple run commands, so it can be deployed quickly on a homelab or internal network. -

Seerr also integrates with backend automation tools such as Sonarr, Radarr, and others to automatically handle content delivery once a request is approved. The project emerged from a merge of similar tools to create a single unified codebase focused on elegant media discovery, streamlined request flows, and a modern UI. It’s designed for both home users and self-hosters who want an easier way to coordinate media requests among family, friends, or community members. Seerr’s architecture supports plugins, themes, and APIs for extensibility, and the community continues to build add-ons and mobile extensions. -

Ionicons
Hand-crafted icons built by Ionic for web apps
Premium designed icons for use in web, iOS, Android, and desktop apps. Support for SVG and web font. Completely open source, MIT licensed and built by Ionic.

Ionicons was made for Ionic Framework, a cross-platform hybrid and Progressive Web App framework. The Ionicons Web Component is an easy and performant way to use Ionicons in your app. The component will dynamically load an SVG for each icon, so your app is only requesting the icons that you need. Also note that only visible icons are loaded, and icons which are "below the fold" and hidden from the user's view do not make fetch requests for the svg resource. If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary. -

Mock Service Worker
Seamless REST/GraphQL API mocking library for browser and Node.js
Mock by intercepting requests on the network level. Seamlessly reuse the same mock definition for testing, development, and debugging. A dedicated layer of requests interception at your disposal. Keep your application's code and tests unaware of whether something is mocked or not. Request the same production resources and test the actual behavior of your app. Augment an existing API, or design it as you go, when there is none. Use Express-like routing syntax to capture outgoing requests. Parameters, wildcards, regular expressions, mocking has never been easier. Browser usage is what sets Mock Service Worker apart from other tools. Utilizing the Service Worker API, which can intercept requests for the purpose of caching, Mock Service Worker responds to captured requests with your mock definition on the network level. This way your application knows nothing about the mocking. -

Design-forward shadcn kit for interfaces that stand out
ReUI is a design-forward component library built for the shadcn/ui ecosystem, offering a large-scale collection of production-ready UI components and layouts intended to accelerate modern React and Next.js development.

nbdime
Tools for diffing and merging of Jupyter notebooks
nbdime provides tools for diffing and merging Jupyter notebooks. Jupyter notebooks are useful, rich media documents stored in a plain text JSON format. This format is relatively easy to parse. However, primitive line-based diff and merge tools do not handle well the logical structure of notebook documents. nbdime, on the other hand, provides “content-aware” diffing and merging of Jupyter notebooks. It understands the structure of notebook documents. Therefore, it can make intelligent decisions when diffing and merging notebooks. Many of us who are writing and sharing notebooks do so with git and GitHub. Git doesn’t handle diffing and merging notebooks very well by default, but you can configure git to use nbdime and it will get a lot better. -
