Comparison

Tree-shakeable entry points

Need	tanstack-fetch
Drop into TanStack Query `queryFn`	Returns data, throws `FetchError`, takes `signal`
Next.js SSR cookies	`ssr-forward` plugin
Interceptors without axios weight	Named, ordered, ejectable plugins
SSE with Authorization	`tanstack-fetch/sse` (not `EventSource`)
File upload + progress	`api.upload()` + `onUploadProgress`
tRPC transport	`tanstack-fetch/trpc`
Bundle	~3.5KB gzip HTTP core

Compared to axios / ky / ofetch: same mental model as Query, smaller core, SSR cookie forwarding, and SSE that can send Authorization.
