Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Vite

  • Does not support Node.js built-in polyfills, requiring manual configuration for CommonJS libraries
  • File watching fails on Windows Subsystem for Linux 2 in certain conditions
  • Smaller ecosystem and community compared to webpack
  • Ampersands in Windows project paths cause module resolution failures

Answered from the vendors’ own pages

Preact: Is Preact free?

Yes, open source under the MIT licence.

Vite: Does Vite support CommonJS dependencies?

Vite automatically converts CommonJS dependencies to ES modules during pre-bundling using esbuild, but it does not support Node.js built-in polyfills. For projects requiring Node builtins, additional configuration may be needed.

Source
Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Vite: Can Vite work offline?

Vite requires internet for initial dependency pre-bundling with esbuild. Once dependencies are pre-bundled and cached, development can continue with local file serving, but full offline development is not supported.

Source
Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

Vite: What are Vite's system requirements on Windows?

Vite can run on Windows, but WSL2 users may experience file watching issues where Vite cannot detect file changes in certain conditions. Windows users with project paths containing ampersands may encounter module resolution failures with npm.

Source
Vite: Does Vite support TypeScript, JSX, and CSS out of the box?

Yes. Vite natively supports TypeScript, JSX, CSS, and WebAssembly without additional configuration needed for basic use.
