Best internationalization solutions for SaaS?

I’m exploring i18n solutions for a SaaS project and comparing tools like i18next, next-intl, LinguiJS, Tolgee, Phrase, Lokalise, and Crowdin. I recently discovered Intlayer, an open-source dev-native CMS that integrates directly with React, Next.js, Vue, and Nuxt. It keeps translations close to code, automates missing keys, and connects to CI/CD. Has anyone here tried it or compared it with Tolgee or Phrase in production?
