No, using WooCommerce on a free web host is not recommended, because it is quite a heavy plugin and will not perform well. We wouldn’t suggest using free hosting for anything other than a personal blog. As soon as you need to depend on performance and reliability or want to brand a website, free hosting is not an option. To run a successful online store you need it to be fast, secure and reliable. Free web hosts will not invest in those things without seeing a return as they are simply too expensive.
