First, we had SquirrelMail and its ilk. Then, Roundcube became the standard. Their dominance is being eroded by Mailpile, RainLoop, and Nylas. Around the edges, we have Peps[1], Mailr[2] & Kite[3] which may all someday take off. Zimbra and the well known groupware vendors (OnlyOffice, Horde, Citadel, Kolab) are competing in more-or-less the same space. Probably dozens of other projects that are on the same level that I have never even heard of. I would love some sort of comparison, even a biased one written by the respective teams. Anyone have useful links?
