Nextcloud Calendar VS CrossBox

Probably at nextcloud calendar app. Source: about 1 year ago

However, what you're describing seems like any simple Calendar will meet the needs (effectively, here's an event are you coming or not?). Might be overkill, but check out Nextcloud in that case (https://apps.nextcloud.com/apps/calendar). Source: about 1 year ago

I have moved from Google calendar to NextCloud calendar self-host and quite happy with it. I use it with Apple Calendar for creating events, etc. Though sometimes it doesn't sync properly, most of the time, it does the job. The only downside is, I would like to connect my domain/email to the calendar but it is not possible with NextCloud, so it is quite inconvenient if someone tries to invite me.

If you are a roll-your-own person, you could install and maintain a NextCloud server. See https://apps.nextcloud.com/apps/calendar and https://nextcloud.com/athome/ this is not for the faint of heart. Source: over 2 years ago

There is nothing good open source , you could roll a bunch of directadmin + almalinux servers and then use something like https://crossbox.io/. Source: 5 months ago

We rolled our own solution using directadmin plus https://crossbox.io/. Source: 11 months ago

Sounds like this is specific to Crossbox (mail.mxlogin.com). Crossbox does have several different webmail solutions, but they are all built in as part of this software that we license: https://crossbox.io. Source: over 1 year ago

Not sure if Crossbox would fit the bill of this subreddit, but check it out: https://crossbox.io/. Source: over 1 year ago

Not free but self hosted you can use crossbox.io I use it it’s reasonably priced. Source: about 2 years ago
