The ITA Matrix can do this (obviously. ITA Matrix can do everything and then some and then some more). So says the wiki:

Kayak has alliance filters (on the left, you can filter between carrier and alliance filters). Hipmunk also lets you filter by alliance under “airlines.” Google Flights works much the same way.
Yes you can try Kayak! It contains an alliance filter!
