CLUSTER HOSTED-SELF-READING · 21 ENTRIES · EARLIEST ENTRY 2026-01-27
Self-hosted ebook library readers
These self-hosted web apps manage and read personal ebook libraries, with upload, organization, and cross-device progress syncing. The dated history is too thin to read a shape from, with only three dated entries before the index start, so the cluster predates the index or its members are undated. Traction is led by bookshelf (366 stars), with cedar-server (10 stars) and Kolibre (9 stars) trailing.
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 1 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
