- Node.js's built-in fetch is powered by a bundled version of undici, from Node.js v18.
- Installing the package gives a newer undici than the one bundled with Node, plus APIs the built-in fetch lacks, such as ProxyAgent, Socks5Agent and MockAgent.
- Gives control over connection pooling and supports HTTP/1.1 pipelining.
- Its README advises keeping fetch and FormData from the same implementation and not mixing the global and undici versions.
