Use Express for REST APIs and web servers in Node.js, especially when you value a minimal core with full control over what you add. It's the most documented Node.js framework with the largest ecosystem of compatible middleware.
Use Ky in browser-only or Deno applications where bundle size matters and you don't need Node.js compatibility. It's a direct replacement for axios in these contexts with a fraction of the footprint.
Express is synchronous by default and has poor built-in TypeScript support. For TypeScript-first APIs, try Fastify or Hono. For full-stack apps with server-side rendering, use Next.js. For edge/serverless, Hono's smaller footprint is better.
Ky doesn't support Node.js's older http module (though it works in Node 18+ with native fetch). For isomorphic code (same HTTP client in browser and Node), use axios or got. For React apps that need caching and state, React Query provides the better abstraction.
