term.js
A terminal written in javascript
term.js is a full xterm-style terminal emulator written in JavaScript. It was designed to bring interactive terminal behavior into the browser and was used by tty.js for web-based terminal sessions. The project includes server and client examples that connect browser terminal input and output through sockets. It supports terminal dimensions, screen keys, title events, terminal writing, data events, destruction on disconnect, and familiar xterm behavior. It also includes keyboard-driven tmux-like selection and copy-paste workflows in addition to mouse selection. The repository is no longer maintained, but it remains an important reference for browser terminal emulation and early JavaScript terminal UI work. -

ttystudio
A terminal-to-gif recorder minus the headaches
ttystudio is a terminal-to-GIF recorder built to capture command-line sessions without the usual external tooling headaches. It can record a terminal session and compile the result into a GIF or APNG using its own built-in writers. The project avoids dependencies such as ImageMagick, ffmpeg, shell scripts, and frame concatenation workflows. It records terminal frames through a pseudo-terminal, renders text using parsed bitmap fonts, and writes the animation directly from captured frame data. Users can record and compile in one step or save frames to JSON for later replay and editing. It also supports frame ranges, custom delays, borders, screenshot mode, custom quit keys, logging options, and APNG palette controls. -

uMatrix
Point and click matrix to filter net requests according to source
Definitely for advanced users. uMatrix does not guarantee that sites will work fine: it is for advanced users who can figure how to un-break sites, because essentially uMatrix is a firewall which works in relaxed block-all/allow-exceptionally mode out of the box: it is not unexpected that sites will break. uMatrix can be set to work in allow-all/block-exceptionally mode with a single click on all cells in the global scope if you prefer to work this way. This will of course break fewer sites, but you would then lose all the benefits which come with block-all/allow-exceptionally mode, though you will still benefit from the 62,000+ blacklisted hostnames by default. HTTP Switchboard's documentation is still relevant, except for uMatrix's differences with HTTP Switchboard. -

volkswagen
Volkswagen detects when your tests are being run in a CI server
Volkswagen is a satirical Node.js package that deliberately interferes with automated tests when it detects a continuous integration environment. It was inspired by Volkswagen's emissions-testing scandal and applies the same “defeat device” idea to software testing. Once required by a project, it detects CI environments and alters failing test behavior so builds appear successful. It recognizes services such as Travis CI, CircleCI, Jenkins, GitLab CI, AppVeyor, Buildkite, and other systems exposing common CI variables. The package can affect tests that fail through thrown errors or nonzero exit codes. It works with testing libraries including assert, tap, tape, and Chai. The project is a programming joke and demonstration rather than a legitimate testing practice. -

workerpool
Offload tasks to a pool of workers on node.js and in the browser
workerpool is a JavaScript library that simplifies the creation and management of worker threads and process pools for parallel task execution in Node.js and browser environments. The project provides an abstraction layer that allows developers to offload CPU-intensive operations to background workers without manually handling thread communication or lifecycle management. It supports task queuing, dynamic worker scaling, timeouts, transferable objects, and proxy-based APIs for interacting with worker functions as if they were local calls. workerpool is designed to improve application responsiveness and throughput in workloads involving heavy computation, data processing, or asynchronous execution. The library works across multiple environments, supporting Web Workers in browsers and Worker Threads or child processes in Node.js. Its architecture emphasizes ease of integration, scalability, and efficient concurrency management for modern JavaScript applications. -

Alpine.js
A rugged, minimal framework for composing JavaScript behavior
Alpine.js is a lightweight JavaScript framework designed to bring declarative, reactive behavior directly into HTML markup, functioning similarly in spirit to Vue but with a much smaller footprint. It’s often described as “jQuery for the modern web,” enabling you to sprinkle interactivity onto static HTML without needing a full SPA framework. You use directives like x-data, x-bind, x-on, x-if, and others to attach reactive state, event listeners, and conditional rendering straight in the DOM. Because Alpine is so minimal, it avoids virtual DOM overhead and focuses on being incremental and composable; you can use it for small interactive components inside traditional server-rendered pages. The project has grown a robust ecosystem (plugins, devtools, helper libraries) as people adopt it for micro-frontend patterns, admin panels, interactive widgets, and anything that benefits from having bits of reactivity without a heavy JavaScript framework. -

Antigravity Claude Proxy
Proxy that exposes Antigravity provided claude / gemini models
Antigravity Claude Proxy is a purpose-built proxy server that enables developers to interface with Claude models through a standardized RESTful API, allowing tools and workflows that expect generic HTTP APIs to operate on Anthropic’s Claude without native support. The project acts as a translation layer, receiving web requests in common formats (such as OpenAI-style endpoints) and forwarding them to Anthropic’s API in the required structure, while converting responses back into a familiar shape. This makes it easier to integrate Claude into existing toolchains, scripts, notebooks, or agent frameworks that do not have built-in support for Anthropic’s native SDKs. It abstracts away key differences like authentication choreography, request schema quirks, and streaming protocols so client code can remain unchanged when switching between models. -

Apisauce
Axios + standardized errors + request/response transforms
Talking to APIs doesn't have to be awkward anymore. Low-fat wrapper for the amazing Axios HTTP client library. All responses follow the same flow: success and failure alike. Responses have a problem property to help guide exception flow, attach functions that get called each request, attach functions that change all request or response data. Detects connection issues (on React Native). The only required property is baseURL and it should be the starting point for your API. It can contain a sub-path and a port as well. The responses are promise-based, so you'll need to handle things in a .then() function. The promise is always resolved with a response object. Even if there was a problem with the request! This is one of the goals of this library. It ensures sane calling code without having to handle .catch and has 2 separate flows. -

AsyncAPI
Allows you to create machine-readable definitions of asynchronous APIs
AsyncAPI is an open-source initiative that seeks to improve the current state of Event-Driven Architecture (EDA). Our long-term goal is to make working with EDAs as easy as working with REST APIs. That goes from documentation to code generation, from discovery to event management, and beyond. The AsyncAPI Specification defines a standard, protocol-agnostic interface that describes message-based or event-driven APIs. The AsyncAPI document allows people or machines communicating with one another to understand the capabilities of an event-driven API without requiring access to the source code, documentation, or inspecting the network traffic. It allows you to define your API structures and formats, including channels the end user can subscribe to and the message formats they receive. You can develop, validate, and convert the AsyncAPI document to the latest version or preview your AsyncAPI document in a more readable way using the AsyncAPI Studio. -
