httpAgentOptions

Last updated April 23, 2026

In Node.js versions prior to 18, Next.js automatically polyfills fetch() with undici and enables HTTP Keep-Alive by default.

To disable HTTP Keep-Alive for all fetch() calls on the server-side, open next.config.js and add the httpAgentOptions config:

next.config.js

module.exports = {
  httpAgentOptions: {
    keepAlive: false,
  },
}
