CLUSTER CALENDAR-GUESTS-SYNC · 23 ENTRIES · EARLIEST ENTRY 2026-07-30
Calendar booking link schedulers
This cluster consists of scheduling apps that let users create shareable booking links, pick free times, and sync events to calendars, with guest booking across time zones. Dated entries before the index start appear at irregular intervals from February 2025 to July 2026, with two entries in July 2026 being the most in a single month. The traction leader is opencalendar, the only product with any activity signal (1 star).
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.

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.
