It is one of the SEO tools available online for website owners who want to use HTML tags on their websites where there are different pages in different languages/regions. This tool helps in telling the search engines which version of the page is for which particular language/region. As an instance, there may be two pages (English and Hindi) on a single website for its users. Instead of writing the tag for each page, you just need to put the URL of the page along with the language code. The Hreflang generator by ToolFlora makes it easier for website owners or SEO people. Before you add those tags to your website, ensure that all language versions point to themselves and other relevant versions.
