With a similar user interface and matching system, OKCupid.com is basically the free version of Match.com. OKCupid lacks some of the detailed matching features of Match.com but is an excellent option if you are just starting to explore online dating.
OKCupid is Match.com without all the bells and whistles. As a free service it's attractive to singles who are new to online dating, and tends to cater to those looking for a more casual dating experience up front. The site has a pairing system similar to Match, and a 'yay or nah' feature that's a bit like Tinder, which makes it one of the most popular dating sites available. Just like Match.com, OKCupid will give you better results the more you use it. Upgrade features are available, which allow you to do things such as browse anonymously and promote your profile for limited amounts of time.
