OSS Tanbou

federate reading activity and reviews across small ActivityPub communities

About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

BookWyrm is a social reading platform for tracking books, publishing reviews, quotes, and comments, and discovering what to read next. ActivityPub federation connects independent BookWyrm instances with each other and with compatible services such as Mastodon.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Treat reading activity and reviews as social content

Users can maintain reading shelves, post reviews and quotes, comment on activity, and discover books through people they follow.

Sources: [2]

Federate independent instances through ActivityPub

Small communities can operate their own instances while following and interacting with users on other BookWyrm or ActivityPub services.

Sources: [2]

Best fit

Fits reading communities that want their own moderation and hosting

It supports interest-based or group-based instances rather than requiring every user to join one centralized service.

Sources: [2]

Before adoption

Federation adds moderation and instance-operations work

Administrators choose federation relationships and are responsible for moderation, upgrades, backups, and ongoing service operations.

The license includes eligibility conditions

Supplemental curator note

BookWyrm provides a Goodreads-like reading experience through small federated communities. GitHub reports NOASSERTION for the license; LICENSE.md contains the Anti-Capitalist Software License 1.4 with explicit eligibility conditions for users and organizations, so it should not be treated like a standard permissive or OSI-style license.
