CLUSTER EMAIL-CLIENT-DESKTOP-2 · 8 ENTRIES · EARLIEST ENTRY 2025-12-17

Desktop clients for secure webmail

This cluster consists of desktop email clients that provide browser-independent access to a private, cloud-based webmail service, with an emphasis on encryption and security features. The dated history is too thin to read a shape from—only one dated entry exists before the index start, and two members have no source date. Among the members, Neirmail-Windows leads in traction with 16 stars, while Proton-Mail-client (1 star) and ElectronMail (0 stars) trail.

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 8 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.
