Top 5 Web Development Tools Growing on GitHub [As of November 6, 2026]｜かえる

This article is part of a series that monitors rapidly growing repositories on GitHub. Since the previous installment covered AI/ML open-source software, this edition focuses on web development tools, introducing editors, UI libraries, design systems, and other tools used in development environments.

The ranking is based on the ‘number of stars gained today’ as verified on GitHub Trending. Repositories already introduced in this series have been excluded. Each repository is accompanied by a conceptual diagram showing what problems it addresses and what it solves.

1st Place: microsoft/vscode

Total 194,802 stars (+295 today)

This is the main repository (Code – OSS) for Visual Studio Code, developed by Microsoft. According to the README, it combines the feel of a simple editor with the core features needed for the development cycle of editing, building, and debugging, including rich code editing, navigation, lightweight debugging, and an extension model. It is updated monthly and can be downloaded for Windows, macOS, and Linux. You should start by installing it from the official website, and those who want to try the latest version daily should choose the Insiders version. For most web developers, this is the standard editor they encounter first.

2nd Place: zed-industries/zed

Total 93,024 stars (+292 today)

A high-performance, multiplayer-ready code editor developed by the creators of Atom and Tree-sitter. The README states that it supports macOS, Linux, and Windows, and can be installed via downloads from the official website or through package managers for each OS. A web version is not yet available. It is suitable for those who prioritize performance and those who want to try collaborative editing within a team. If you are looking for a replacement for VS Code, it is worth trying out.

3rd Place: react/react

Total 252,053 stars (+244 today)

A JavaScript library for building user interfaces. The features highlighted in the README include a ‘declarative’ style that allows you to design simple views for each state, and a ‘component-based’ approach that combines encapsulated parts that manage their own state. It is designed for gradual adoption, meaning you can introduce as much or as little as you need; for new projects, you can start from the Installation section on react.dev. This repository is essential for both those who have just started web development and those who want to partially introduce it into existing projects.

4th Place: meta/astryx

Total 14,035 stars (+181 today)

This is the open-source version of a design system that has been developed within Meta for eight years and supports over 13,000 apps; it is currently in beta. It provides a complete set of over 150 accessible components, themes, dark mode, templates, and a CLI, allowing you to use typed React components without build plugins. Styles can also be used in conjunction with Tailwind or CSS Modules, and the design is such that AI assistants can be handled with the same CLI. It requires React 19 or later and is installed via ‘npm install @astryxdesign/core @astryxdesign/theme-neutral @stylexjs/stylex’. It is suitable for frontend teams looking to standardize their UI.

5th Place: southleft/figma-console-mcp

Total 3,161 stars (+179 today)

An MCP server specialized for design systems for Figma. The README declares ‘Your design system as an API’ and explains that AI can move bidirectionally between Figma and code, allowing for writing to Figma and definitively checking the consistency, accessibility, and health of the design system between design and code. It passes variables, variants, and more to the AI as structured data. For Claude Code, the basic registration command is ‘claude mcp add figma-console -s user — npx -y figma-console-mcp@latest’, and setting a Figma access token is also required. It is suitable for those who want to leave the bridge between designers and developers to AI.

Summary

This time, the lineup included two standard editors, a UI library, a design system, and an MCP server connecting AI and design. While the foundation of editors and React continues to be supported, Meta’s design system and tools that allow AI to directly handle design information have entered the top ranks, highlighting a trend where ‘humans and AI create things by sharing the same parts and information.’ Next time, we plan to deliver the AI/ML open-source software edition.
