How they compare
Both are free, ad-supported tubes with huge libraries.
Pornhub, from Aylo, has verified amateur and professional uploaders and a polished site. Because of age-verification laws it's blocked in many US states and some countries.
SpankBang is built mostly on user uploads, with a large share in HD and 4K and good search and playlists. SpankBang Premium, from about $9.99 a month, removes the ads.
