It's been a while since I've done a collection (maybe month ago), but today let's look at 12 new and not-so-new projects that can really help you in development.

They touch on different areas of development, but we will mainly talk about web development.

If there's a project worth adding to the next collection, feel free to write about it in the comments, and maybe it will be included.

And we will continue, of course, with AI projects. This tool will allow you to work in one convenient interface with many popular LLMs.

OpenWork is the desktop app that lets you use 50+ LLMs.

If you know a YouTuber like Theo, then you should know this project. It's an OpenCode alternative that lets you work with AI in an easy-to-use chat interface.

It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app.

A **truly legendary** engine like Unity or Unreal Engine for games. If you are a game developer, you should know this project. From pet projects for the university to multi-million dollar games - it gives it all.

If you would like to make it possible to create videos on your website by writing just one prompt, then this tool is perfect for you.

Create real MP4 videos with React. Use coding agents, build apps and render in bulk.

If you’ve ever wished Express had a bit more structure, Nest.js is the upgrade you’ve been looking for. It brings TypeScript, OOP, and a modular architecture to Node.js development.

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses modern JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

The following project is a server implementing the MCP protocol that connects LLM directly to a GitHub repository.

GitMCP is a free, open-source, remote Model Context Protocol (MCP) server that transforms any GitHub project (repositories or GitHub pages) into a documentation hub.

The next tool from Vercel allows you to create user interfaces literally from a json object.

Predefined components and actions for safe, predictable output.

If you've ever worked with Scratch, then you may be familiar with a slightly similar interface. This project will allow you to create AI agent workflow in a practical builder.

Open source agentic systems development platform.

An excellent framework from Apple that will allow you to teach your MacBook, iMac and other devices to solve many necessary tasks for business and more.

MLX is designed by machine learning researchers for machine learning researchers. The framework is intended to be user-friendly, but still efficient to train and deploy models. The design of the framework itself is also conceptually simple.

Well, the last project, no, not an AI project, but a small javascript library for working with fonts and text at all.

``` js
const prepared = prepare(textareaValue, '16px Inter', { whiteSpace: 'pre-wrap' })
const { height } = layout(prepared, textareaWidth, 20)
```

Pretext side-steps the need for DOM measurements (e.g. getBoundingClientRect, offsetHeight), which trigger layout reflow, one of the most expensive operations in the browser. It implements its own text measurement logic, using the browsers' own font engine as ground truth (very AI-friendly iteration method).

In this article, I have reviewed only a small part of the volume of projects that are important and even necessary for every developer to know. It is clear that, well, let's say, there are hundreds of such projects today, and maybe more. But I hope you have discovered something new, and if not, at least remembered that there is.

**Thank you very much for reading this article ❤️!**

*What other projects do you know that are not so popular, but also useful? It will be interesting to find out in the comments!*
