next-lang is a lightweight, zero-routing localization package built for Next.js and React. It removes the need for complex folder structures like /[locale]/, locales/, or changing the URL during language switches. Instead, it offers a minimal setup with centralized translations, full control over the current language state, and clean integration into your frontend logic.
Designed for developers who want simple, state-driven internationalization in modern frontend apps — without the overhead.
