JMAP for Calendars, Contacts and Files Now in Stalwart

Reading weirdly many “but there are no clients” posts. Of course something has to come first. You can’t really develop a client without a server implementation and Stalwart is essentially the first server implementation of JMAP.

With Stalwart in place, there’s finally a reason to develop a client for JMAP.

I hope y’all are aware that Mozilla’s new mail service will use it, so that is likely going to give JMAP a big push!

There are clients. I use one called aerc.

Cyrus was probably the first

I'm cautiously optimistic that Stalwart is a game-changer. I would normally stick with a simpler platform (like mox) if I wasn't interested in the groupware space. I've previously tried Nextcloud and SoGo and left disappointed, and have more or less been waiting for a project like this to come along.

Nextcloud was such a terrible experience for me (the file sharing/storage was good, but the groupware aspect was incredibly buggy). But knowing that Nextcloud is partnering with Stalwart to hopefully overhaul their stack, Opencloud is developing their JMAP integration, and Mozilla/Thunderbird is using it too (they already have a webmail in development here: https://github.com/thunderbird/stormbox)... we might finally see some exciting development in this space. And now is also a ripe time, as there seems to be a perfect storm of people wanting to get away from Big Tech platforms.
