Yes, Webkul Magento Multi Vendor Marketplace supports Multi-sites & Multi-stores. By default, Magento provides a single language and single currency support. For the multi-store, the admin will create multiple store views for multiple languages in the back-end. Like for the English, the admin will create a store view and for the French language, admin will create another store view. Now these store views are reflected on the vendor’s side for the product upload.

For the multi-sites, the admin can create separate store views for each language in the back-end and the URLs for all the multi-sites will be same.
