Sistrix Hreflang tool is super easy to use. Unfortunately, it is not intended for larger websites with many language/country versions and it does not allow bulk upload. For individual URLs, one of my favourite tools.

@HermanTinkura Also, Merkle can test hreflang specified in sitemap; my tool can’t. But Merkle can’t bulk test list/sitemap of URLs, I can :)
