A CalDAV client with offline sync and conflict resolution. Works with iCloud, Nextcloud, and other CalDAV servers.
Requires JVM 17+ and Kotlin 1.9+. Android module requires API 21+.
Full iCalendar parsing and generation. Recurring events, timezones, alarms, and more.
Queue changes offline and sync when connected. Automatic conflict resolution.
Automatic CalDAV server and calendar discovery. Just provide credentials.

val client = CalDavClient.forProvider(
serverUrl = "https://caldav.example.com",
username = "user@example.com",
password = "password"
)
val discovery = client.discoverAccount(serverUrl)
if (discovery is DavResult.Success) {
val calendar = discovery.value.calendars.first()
// Create event
val event = ICalEvent(
uid = UUID.randomUUID().toString(),
summary = "Team Meeting",
dtStart = ICalDateTime.fromInstant(Instant.now()),
dtEnd = ICalDateTime.fromInstant(Instant.now().plus(1, ChronoUnit.HOURS))
)
client.createEvent(calendar.href, event)
