What you gain

  • No per-word or per-language-tier billing as your site grows
  • Translations live in your own repo or database, not a vendor proxy
  • Self-hosted so your content is not routed through a third-party service
  • No vendor lock-in on your translated content

What you give up

  • No drop-in JavaScript snippet that translates an existing site with no code changes
  • No automatic content detection and translated subdomains managed for you
  • No built-in machine-translation, you connect your own engine
  • More integration work to get strings out of your app and back in

Switching Cost

Weglot's value is that you paste one snippet and your whole site is translated, with no code changes. That convenience is exactly what you give up. Weblate and Tolgee manage translations properly, but they expect your strings to live in your codebase, so moving off Weglot usually means actually internationalizing your app instead of proxying it. A small content site faces real work here. A team already using i18n libraries in their code switches the management layer in a week. The hidden cost is the engineering to extract strings Weglot was translating on the fly.

What open source can't replace

Weblate and Tolgee replace the translation management, but not Weglot's core trick: translating an existing site with a single snippet and no code changes. Moving off Weglot usually means internationalizing your app properly first.
