CLUSTER CALDAV-CALENDAR-DESKTOP · 25 ENTRIES · EARLIEST ENTRY 2024-11-09
CalDAV calendar apps
This cluster consists of calendar and task management applications that sync with CalDAV servers, often also supporting local, Google, Microsoft, or iCloud calendars, with desktop, terminal, widget, or self-hosted web interfaces. Pre-index dated entries span from October 2013 to July 2026, starting with a single entry in 2013, then isolated entries in 2018 and 2022-2024, before a denser run of releases from late 2025 into 2026. The only member with any activity signal is 'lucid' (1 star); 'clockenstein' and 'movie-planner' each have 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 5 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
