-Ky targets [modern browsers](#browser-support) and [Deno](https://github.com/denoland/deno). For older browsers, you will need to transpile and use a [`fetch` polyfill](https://github.com/github/fetch) and [`globalThis` polyfill](https://github.com/es-shims/globalThis). For Node.js, check out [Got](https://github.com/sindresorhus/got). For isomorphic needs (like SSR), check out [`ky-universal`](https://github.com/sindresorhus/ky-universal).
