How can I easily redirect my website to a specific URL with language detection using Webflow?

TL;DR
  • Inject JavaScript in Webflow’s Project Settings > Footer Code to detect browser language using the Navigator Language API.
  • Redirect users to the matching language-specific URL if on the root domain, avoid redirect loops using pathname checks, and optionally set a cookie to prevent repeated redirects.

To redirect your Webflow website to a specific URL based on user language, you’ll need to use custom JavaScript since Webflow doesn’t support language redirects natively.

1. Use the Navigator Language API

  • The browser exposes the user’s language via navigator.language or navigator.languages.
  • You can use this to determine the visitor’s preferred language and redirect them accordingly.

2. Add Custom Code in Webflow

  • Go to Project Settings > Custom Code > Footer Code.
  • Add a script that runs on page load and checks the language.

Example logic (don’t paste raw code, just the behavior):

  • Detect if the browser language starts with "fr", then redirect to your French site (e.g., example.com/fr).
  • If it starts with "es", redirect to example.com/es, and so on.
  • For all other languages or fallbacks, redirect to the default homepage.

3. Prevent Redirect Loop

  • Only run this script on the root domain (like example.com) and not on already localized URLs (example.com/fr, etc.).
  • You can check the current window.location.pathname and exit early if it's already a subpath.

4. Use with Webflow Hosting Structure

  • Make sure your language-specific pages or folders (e.g., /fr, /es) exist in Webflow.
  • These can be created as folders with their own homepage (index.html inside folder).
  • Use JavaScript to set a cookie after the first redirect.
  • Check that cookie before redirecting again, avoiding unnecessary bounce for return users.

Summary

To redirect users to a language-specific URL in Webflow, inject a JavaScript snippet using the Navigator Language API via Project Settings > Footer Code. Build conditional logic to check the user's language, redirect to the appropriate localized path, and ensure you avoid infinite loops by targeting only the root URL.
