## What it is
Ky is a tiny, zero-dependency JavaScript HTTP client built on the Fetch API, offering a simpler API with method shortcuts, automatic retries, timeouts, JSON handling, hooks, and TypeScript support. It works in modern browsers, Node.js, Bun, and Deno.

## Use cases
- make http requests in javascript without boilerplate
- wrap fetch with retries and timeouts
- post  to a rest api
- treat non-2xx responses as errors automatically
- create http client instances with custom defaults
- track upload and download progress
- validate api responses with zod

## When to choose
- you want a lightweight axios alternative built on fetch
- you need retries, timeouts, or hooks on top of fetch
- you target modern browsers, Node.js, Bun, or Deno
- you want better TypeScript ergonomics than raw fetch

## When to avoid
- you need to support legacy browsers without fetch
- you need interceptors or features only axios provides
- you need request cancellation via AbortController wrappers with advanced semantics

## Facets
- artifact type: library
- maturity: stable
- function: http-client
- domain: web-development, apis, developer-tools
- platform: browser, bun, cross-platform
- tags: fetch-api, rest, typescript, zero-dependency, retry, timeout, nodejs, deno
