CodexPro
Use ChatGPT Developer Mode as a local coding agent for your repo
CodexPro is a local MCP bridge that lets ChatGPT Developer Mode work inside a specific code repository. It starts a local server for the current workspace so ChatGPT can read files, search code, apply scoped edits, run guarded shell checks, and review changes. The project is designed around local control rather than hosting code or proxying model access through a third-party service. It supports setup, start, doctor, settings, handoff, and pro modes for different levels of agent involvement. Public access can be routed through options such as Cloudflare tunnels, ngrok, Tailscale Funnel, or local-only mode. CodexPro is useful for developers who want ChatGPT to act like a repo-aware coding assistant while keeping the actual workspace on their own machine. -

Context Hub
Makes coding agents get smarter with every task
Context Hub is a curated documentation system built to help coding agents write more accurate code. It gives agents versioned, language-specific reference material instead of forcing them to rely on noisy web searches or stale model memory. The project includes a CLI called chub that agents can use to search for available docs, fetch specific API guidance, and request only the files they need. It also supports local annotations, allowing an agent to remember project-specific notes, pitfalls, or workarounds across future sessions. Feedback can be sent back to maintainers so shared documentation improves over time. Context Hub is especially useful for teams that use AI coding assistants and want more reliable API usage, fewer hallucinated calls, and a transparent source of agent-readable context. -

Crypto Arbitrage
A cryptocurrency arbitrage opportunity calculator
A cryptocurrency arbitrage opportunity calculator and trading bot. Over 800 currencies and 50 markets. In short, it collects JSON from multiple different cryptocurrency markets, goes through the results, and finds the highest and lowest price for each coin. The script will find the highest price (chbtc.com), and lowest price (Bittrex), and divide the two: 51.8/38.23 = ~1.35 (~35% profit margin) and then push these results to the browser. It will also find the next highest market pairs, e.g. chbtc / jubi is the second-highest pair and chbtc/Bittrex the third, jubi/Bittrex the fourth and so on until every possible combination has been computed. Currently you will have to add a market object with the correct settings in the array markets, situated in the settings.js file. I am updating the project every day and this will change soon. You can temporarily stop loading a market from the frontend, or remove the market by deleting the object in settings.js. -

DISCORD.js-selfbot
An unofficial discord.js fork for creating selfbots
DISCORD.js-selfbot is an archived Node.js library based on discord.js that targets Discord user-account API behavior instead of normal bot accounts. It exposes structures for messages, guilds, interactions, status, activity, voice, video, and other user-specific Discord features. The project was built around Discord API v9 and backported selected functionality from later discord.js versions. It includes documentation, examples, tests, and npm distribution history, but the repository is no longer actively maintained. Because automating Discord user accounts violates Discord’s Terms of Service and can lead to account penalties, this project should be treated as a risky proof-of-concept or research library. It is not appropriate for compliant production bot development. -

EJS
Embedded JavaScript templates for node
EJS is a templating engine for JavaScript/Node.js that allows developers to embed plain JavaScript code into HTML markup. The idea is to avoid introducing a separate DSL for templating and instead use familiar JavaScript logic inside template tags to generate dynamic content. You write templates using <% %> scriptlet tags, <%= %> for output, and you can include other templates, pass data, and control flow with loops and conditionals. It’s fast because it compiles templates to JavaScript functions and caches them by default, so subsequent rendering is efficient. EJS supports both server-side render (in Node/Express) and client-side use in the browser, making it versatile for universal apps. Because you’re using raw JS, debugging is simple—the errors are standard JS stack traces with template line numbers included. While it doesn’t impose a rigid structure (you’re free to organize templates however you like), it works reliably and is simple to adopt. -

Easings.net
Easing Functions Cheat Sheet
Easings .net is a visualization and reference project dedicated to easing functions, which are widely used in animations and transitions to create natural motion. Instead of linear changes, easing functions help define how values accelerate or decelerate over time, resulting in smoother and more dynamic effects. The project provides a clear, interactive showcase of common easing equations such as quadratic, cubic, quartic, and elastic functions. It is a valuable resource for developers and designers who want to understand and compare different easing behaviors before applying them to web animations, game mechanics, or UI interactions. With its focus on simplicity and clarity, Easings .net has become a popular go-to reference for motion design and development. -
