CLUSTER CLIENT-HOSTED-IMAP · 4 ENTRIES · EARLIEST ENTRY 2026-10-02

Self-hosted keyboard-first email clients

This cluster consists of self-hosted email clients that connect to IMAP/SMTP servers, with an emphasis on keyboard-first and AI-assisted interfaces. Its dated history is too thin to read a shape from: it predates the index or its members are undated. On traction, mailmomo-oss leads with 8 stars, ahead of mailwick (3 stars) and slipstream (1 star).

Entry timeline

ENTRY TIMELINE

OCT 2026: 4
OCT 2026

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.
