MatchMyType

MatchMyType is a free MBTI compatibility site. Choose your type and another person's type to get compatibility scores across three dimensions (love, work and friendship) plus a long-form analysis of how the two types communicate, where they clash and how to make the relationship work.

Every one of the 136 pairings, including same-type pairs, has its own page, and each type has a ranking of its best and most challenging matches. Pages are available in English, Japanese and Korean, and no account is needed to read them.

There is also a 16-type personality test: the basic result is free and a full personality report is an optional paid upgrade.
