OpenPromptStudio
Visual editor for AI prompts with translation, categories, and tools
OpenPromptStudio is an open source visual editor designed to help users create, organize, and manage prompts for AI image generation tools. It focuses on improving the workflow for building prompts by turning them into structured, visual components that are easier to edit and rearrange. It supports the creation and classification of prompt segments, allowing users to organize them into different types such as styles, quality modifiers, commands, or general prompt elements. OpenPromptStudio also provides translation capabilities that can convert Chinese prompts into English and display Chinese translations for English prompts, which is especially useful for tools that require English inputs. A built-in prompt dictionary helps users quickly access commonly used prompt fragments and reuse them in different projects. Users can optionally manage and maintain this dictionary using a connected workspace database, enabling more flexible prompt organization. -

Optimize JS
Optimize a JS file for faster parsing
Optimize JS is an experimental JavaScript transformation tool created to reduce initial parsing and execution time in older browser engines. It parses JavaScript into a syntax tree and identifies functions that are immediately invoked or likely to execute eagerly. Those functions are wrapped in parentheses so engines such as older V8 versions can avoid unnecessary lazy preparsing. The tool can operate from the command line or through a JavaScript API and can optionally generate source maps. Plugins were also created for Grunt, Gulp, and webpack workflows. Historical benchmarks showed improvements in several older browsers, but results varied significantly by engine and workload. The project is unmaintained, and its author and the V8 team now advise against assuming the technique benefits modern browsers. -

PawWork
Selection-first web agent for Chrome
PawWork ZhuaZhua is a Chrome extension that turns an already logged-in browser session into a workspace for an AI web agent.

The extension can execute browser-side actions and guest JavaScript through its sandboxed runtime. It supports editable artifacts such as spreadsheets, document-style content, and generated site HTML. Model access is bring-your-own-key and credentials are stored locally in Chrome rather than routed through a hosted PawWork server. The project installs as an unpacked Manifest V3 extension and requires a recent Chrome release. -

PoisonTap
Exploits locked/password protected computers over USB
PoisonTap is a security research project that demonstrates risks involving USB networking, locked computers, browser sessions, and internal network exposure. It was created to show how a small device can emulate network behavior when connected to a computer over USB. The project became notable because it highlighted how physical access, even for a short time, can create serious security problems. It is best understood as a proof of concept for awareness, testing, and defensive hardening rather than a general-purpose utility. PoisonTap also illustrates why organizations need strong endpoint policies, USB restrictions, browser protections, and network segmentation. Its main value is educational: it makes invisible trust assumptions in desktop networking much easier to understand. -

Pokémon Cards CSS
Collection of advanced CSS styles to create realistic-looking effects
pokemon-cards-css is a CSS-driven styling framework that lets web developers render Pokémon card visuals purely in HTML and CSS. It defines layouts, frames, typography, and image placeholders to mimic the look of real Pokémon trading cards, enabling users to create “virtual cards” with custom content. Because the design is built into CSS, cards respond to responsive constraints and adjust nicely across devices. The project supports common card types (basic, stage, trainer, etc.), and includes classes to manage energy symbols, attack boxes, and flavor text. Many community users combine it with JavaScript to dynamically generate cards from data (e.g. Pokédex entries or user input). It offers a playful, educational example of what you can achieve with modern CSS, especially in combining design fidelity with flexible markup. -

Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync.
