Mako
Fast JS bundler.
What we like
Zero config - supports bundling CSS, images, WASM, fonts, polyfills, etc from JS/TS. Hot reload (HMR) with component-level reloading. Configurable code splitting and tree shaking. Faster than every other bundler.
What we don't like
Only supports macOS and Linux. Not compatible with Webpack (which is a feature so they can go their own way, but worth highlighting).
