Neiki's Editor
Lightweight WYSIWYG Rich Text Editor
Neiki's Editor is a WYSIWYG rich text editor written in plain JavaScript with zero dependencies. You attach it to an existing <textarea> (or any element), and it becomes a full editing surface — toolbar, formatting tools, tables, images, video, and a status bar — without pulling in a framework or a build step. Most rich text editors ask you to make a trade-off: either pull in a dependency tree and a bundler, or commit to a specific framework. Neiki's Editor avoids that trade-off. One file, no dependencies. The editor ships as a single script. The minified build embeds its CSS, so there is nothing else to install, import, or bundle. Drop it into a static page, a PHP template, or a SPA component — it behaves the same way. Zero-config by default, configurable when you need it. new NeikiEditor('#editor') gives you the full toolbar immediately. Every option is optional, so you only reach for configuration when you actually want to change something. -

90s Cursor Effects
Old-school cursor effects for your browser built with modern JS
"Knowing the codes" used to be all the rage, I want to bring a few back. A repo of the old effects that inspired creativity and the desire to learn at least a little code around the world. Modernized so they're a little more efficient, and just as annoying (and twice as fun) as they were before. -

AI Shell
CLI tool turning natural language into executable shell commands
AI Shell is an open source command-line interface tool designed to translate natural language instructions into executable shell commands, helping users interact with their terminal more intuitively. It acts as a bridge between human intent and command-line syntax by leveraging large language models to interpret plain English input and generate accurate commands. This approach reduces the need to memorize complex command structures, making it especially useful for beginners or users working across different environments. AI Shell is inspired by similar AI-assisted terminal workflows but is made openly available for customization and extension. It integrates into a developer’s existing workflow by running directly in the terminal and responding to prompts with suggested commands. Users can configure it with an API key and begin issuing requests immediately, making setup relatively straightforward. -

AI-Media2Doc
AI tool converting video/audio into structured documents instantly
AI-Media2Doc is a web-based application that uses large language models to convert video and audio content into structured, readable documents in a single workflow. It is designed to transform multimedia inputs into formats such as knowledge notes, summaries, mind maps, and social-style articles, making content easier to review and reuse. AI-Media2Doc emphasizes privacy by processing media locally in the browser using WebAssembly-based ffmpeg, ensuring that original video files are not uploaded externally. It separates client-side media handling from backend AI processing, reducing data exposure while still enabling transcription and document generation. AI-Media2Doc supports flexible customization through prompts, allowing users to tailor output styles based on their needs. It also includes features like subtitle export and AI-assisted follow-up questioning for deeper interaction with the generated content. -

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. -

Atropos
Stunning touch-friendly 3D parallax hover effects
Atropos is a lightweight, open-source JavaScript library designed to add visually striking 3D parallax and hover effects to webpage elements — giving a sense of depth and interactivity when users hover or touch elements (cards, images, UI components). It works not only with vanilla JavaScript, but also provides integrations or support for modern frameworks (React, Vue, Web Components, etc.), making it easy to incorporate into a variety of web projects. Because Atropos is very small (just ~2 KB minified + gzipped) and has zero dependencies, it's ideal for performance-conscious applications and does not bloat bundle size. Developers can customize parameters — for example, perspective, rotation, scale, and responsiveness to pointer/touch events — to fine-tune how elements respond to user interaction. -

Babel Loader
Babel loader for webpack
This package allows transpiling JavaScript files using Babel and webpack. Within your webpack configuration object, you'll need to add the babel-loader to the list of modules. You can pass options to the loader by using the options property. Make sure you are transforming as few files as possible. You can also speed up babel-loader by as much as 2x by using the cacheDirectory option. This will cache transformations to the filesystem. Babel uses very small helpers for common functions such as _extend. By default, this will be added to every file that requires it. You can instead require the Babel runtime as a separate module to avoid the duplication. Webpack supports bundling multiple targets. For cases where you may want different Babel configurations for each target (like web and node), this loader provides a target property via Babel's caller API. -

Bloom
An open source, agentic Loom alternative
Bloom is an open-source, agent-centric video recording and processing platform designed as a modern alternative to tools like Loom, but with a strong emphasis on AI-driven workflows and programmability. It allows users to record sessions locally while simultaneously preparing those recordings to be processed, indexed, and analyzed by AI systems, effectively turning simple screen captures into structured, queryable data. The project is part of the broader VideoDB ecosystem, which focuses on giving AI agents perception and memory through video, enabling them to understand and act upon visual information. Bloom supports the concept of “agentic video,” where recordings are not just passive media files but interactive assets that can be searched, summarized, and transformed into workflows or insights. This makes it particularly useful for use cases such as debugging AI agents, documenting processes, training models, or creating automated video-based reports. -

Chalk
Terminal string styling done right
Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now. Chalk comes with an easy to use composable API where you just chain and nest the styles you want. Chain styles and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that chalk.red.yellow.green is equivalent to chalk.green. Color support is automatically detected, but you can override it by setting the level property. You should however only do this in your own code as it applies globally to all Chalk consumers. Detect whether the terminal supports color. Used internally and handled for you, but exposed for convenience. chalkStderr contains a separate instance configured with color support detected for stderr stream instead of stdout. Override rules from supportsColor apply to this too. supportsColorStderr is exposed for convenience. -

Commander.js
node.js command-line interfaces made easy
The complete solution for node.js command-line interfaces. Commander exports a global object which is convenient for quick programs. For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|'). Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value). You may specify a function to do custom processing of option-arguments. The callback function receives two parameters, the user specified option-argument and the previous value for the option. It returns the new value for the option. This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing.
