next.js
Next.js is a React framework for building full-stack web applications, extending current React features and using Rust-based JavaScript tooling for builds. This repository is the framework itself, not an AI starter. It is the base that many AI web app templates build on.
Who it is for: Web developers building React apps, including AI products on top
Strengths
- Full documentation, a Learn course and a showcase of production sites
- Rust-based tooling is used for builds
- MIT license, with a recent release and recent commits
- GitHub Discussions, Discord and a bug bounty program
Weaknesses
- Framework only: no built-in AI features, auth, billing or database
- README gives no install steps, version requirements or feature list
- Not an AI project; relevant here only as a dependency of starters
- README does not describe hosting or deployment options
- JavaScript
- Needs React
heroui
HeroUI (formerly NextUI) is a React component library that pairs React Aria accessibility primitives with Tailwind CSS v4 styling. It uses a compound component API such as Card.Header and Card.Content, needs no Provider wrapper, and targets React 19 and Next.js. It also publishes an MCP server (@heroui/react-mcp), llms.txt and agent skills for AI coding tools.
Who it is for: React and Next.js developers building SaaS UIs and dashboards
Strengths
- Built on React Aria for keyboard, focus and screen-reader behavior
- Tailwind CSS v4 styling with no CSS-in-JS runtime
- No Provider wrapper; per-component subpath imports available
- Ships MCP server, llms.txt, AGENTS.md download and agent skills
Weaknesses
- UI library only; no auth, billing, database or AI features included
- React and Tailwind v4 only; no support for other frameworks
- v3 API differs from v2, so older NextUI code needs migration
- Not copy-paste source like shadcn/ui; customization goes through the library
- TypeScript
- Needs React 19, Tailwind CSS v4
