Your Data Never Leaves Your Device
Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The Next.js Config Generator lets you build a complete next.config.js file by toggling options instead of memorising the API. It covers the most commonly-used settings — strict mode, output targets, image domains, i18n, and experimental flags.
Once you're happy with the options, hit Copy or Download to drop the file straight into your project root. Everything runs in your browser — no data is sent anywhere.
