A multilingual website is more than just translating text. Proper internationalization includes language-based routing, per-language SEO, a language switcher, and a translation management system. This very website runs in both Czech and English — that’s the best proof of concept.
I work with Astro i18n, but I also have experience with other approaches like i18next or react-intl. The key is choosing a solution that doesn’t slow down the site or complicate adding more languages in the future.
