Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Bun

- Native Node.js addons not supported directly; requires FFI workarounds for C libraries
- Ecosystem less mature than Node.js; fewer third-party packages optimised for Bun
- Windows support newer and less mature than Linux/macOS; occasional edge cases
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
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.
SourceVite: 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.
SourceVite: 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.
SourceVite: 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.
