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.

TikTok Live Connector

Node.js library to receive live stream events

TikTok Live Connector is a Node.js library for receiving real-time TikTok LIVE events from TikTok’s internal Webcast push service. It can connect to a live stream by username and listen for events such as comments, gifts, member joins, follows, shares, questions, likes, subscriptions, viewer updates, and battles. The library does not require user credentials for basic live chat connection, which makes it useful for overlays, chat readers, bots, dashboards, alerts, and livestream interaction tools. It is a reverse-engineering project rather than an official TikTok production API, so developers should expect platform changes and occasional breakage. Recent development has focused on a more modular TypeScript architecture and expanded event schema support. It is best used for experiments, prototypes, creator tools, and non-critical realtime TikTok LIVE integrations.

KnowNote

A local-first AI knowledge base & NotebookLM alternative

KnowNote is a local-first, open-source AI knowledge base and notebook application created as an Electron-based alternative to Google NotebookLM that emphasizes privacy, control, and simplicity. It lets users build an intelligent, searchable knowledge base from uploaded documents such as PDFs, Word files, PowerPoints, and web pages, and then interact with that content using LLM-powered chat, summarization, and reasoning tools. Unlike many NotebookLM alternatives that rely on Docker or cloud deployments, KnowNote runs natively on desktop platforms without complex setup, meaning all data stays local unless the user opts to integrate with self-managed or private LLM APIs. Its retrieval-augmented generation (RAG) system offers semantic search and traceable source references, and it supports multiple LLM providers through a flexible plugin-style provider architecture.

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.

brain.js

GPU accelerated Neural networks in JavaScript for Browsers

GPU accelerated Neural networks in JavaScript for Browsers and Node.js. brain.js is a GPU accelerated library for Neural Networks written in JavaScript. Brain.js depends on a native module headless-go for GPU support. In most cases installing brain.js from npm should just work. However, if you run into problems, this means prebuilt binaries are not able to download from GitHub repositories and you might need to build it yourself. Brain.js is super simple to use. You do not need to know Neural Networks in detail to work with this. Brain.js performs computations using GPU and gracefully fallback to pure JavaScript when GPU is not available. Brain.js provides multiple neural network implementations as different neural nets can be trained to do different things well. Easily export and import trained models using JSON format or as a function. Host pre-trained models on your website easily.

Driver.js

A lightweight, dependency-free JavaScript library

Driver.js is a lightweight, framework-agnostic JavaScript library for building guided tours, feature spotlights, and product walkthroughs. It programmatically highlights elements on a page, dims the background, and attaches callouts so users learn new flows without leaving the UI. The API lets you define steps, order, and behavior, while handling positioning, scrolling, and viewport collisions gracefully. It strives to be unobtrusive: tours can be triggered contextually, resumed, or dismissed without hijacking the app. Accessibility and keyboard interaction are considered so tours remain usable beyond simple mouse clicks. Because it has no hard dependency on a specific framework, it integrates into vanilla JS apps or modern stacks alike.
