WMR is a tiny all-in-one development tool for modern web apps, packaged as a single 2MB dependency-free file. It provides a zero-config dev server with hot reloading, npm package handling without installation, and Rollup-based production builds with static prerendering.

Use cases

• serve a directory of HTML files with ES modules without configuration
• develop a Preact app with hot module reloading
• build and prerender a web app to static HTML for production
• import npm packages during development without installing them
• use TypeScript and CSS Modules with no setup
• scaffold a new modern web app project quickly

When to choose

• you want a zero-config dev server and bundler for a small Preact or ES module app
• you need fast startup and HMR without heavy tooling
• you want Rollup plugin compatibility in a lightweight tool

When to avoid

• starting any new project - the project is officially unmaintained and recommends Vite with @preactjs/preset-vite instead
• you need long-term support, security updates, or modern ecosystem compatibility
• you need a robust production build pipeline
