esbuild is a high-performance JavaScript/TypeScript/CSS bundler and minifier written in Go, designed to be 10-100x faster than traditional web build tools. It offers a unified CLI, JS, and Go API with built-in support for ESM/CommonJS, JSX, tree shaking, source maps, and plugins.
PostCSS is a tool for transforming CSS with JavaScript plugins. It parses CSS into an abstract syntax tree, lets plugins inspect and mutate it, then stringifies the result — powering everything from autoprefixing to future-syntax polyfills and minification.
Mitosis is a compiler that lets you author UI components once in a JSX-like syntax and transpile them into idiomatic code for many frameworks — React, Vue, Angular, Svelte, Solid, Qwik, web components and more. It's the open-source engine behind Builder.io's cross-framework component delivery.
