I hope this message finds you well.
I would like to request the addition of radicale to our community apps section. This app is a calDAV server which could greatly benefit the community.
I was used to having it with truecharts but it won’t be supported on next Truenas update. I really don’t care about truechart but i will miss my Radicale app.
Alternative that I have used for 5 years, and definitely not as simple, is nextcloud. I use it for my reminders, calendar, address book, etc instead of Apple stuff.
Not saying it’s a better choice for you and some think it’s not reliable (more of an experience thing than anything, never had a problem with it.) It’s a side effect of me using nextcloud as it does carddav and caldav also.
