AFFiNE vs Kavita: at a glance
What is AFFiNE?
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
What is Kavita?
Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.
Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.

AFFiNE
5.0COLLAB
AFFiNE's canaries stay on upkeep: a Swift Collections bump follows CVE and migration fixes.
◆ Current state
AFFiNE ships a canary build almost daily, and nearly all of October has been dependency and infrastructure work. The newest, canary 915, bumps Apple's Swift Collections package to 1.7.4 for the native apps. Before it came a happy-dom code-execution CVE patch, payment-record repairs during a data migration, and non-root, read-only containers with multi-architecture Windows builds.
◆ Where it's heading
The feed reads like a team hardening the backend and toolchain ahead of a larger cutover: a payment-identity migration, stricter deployment defaults and steady Renovate bumps across web, server and native code. Feature work isn't visible in canaries this month; the last user-facing fix was October 12's blob-upload quota correction.
◆ Prediction
Expect the data migration to finish in the next canaries, followed by a stable release that bundles it; the entries don't show which user-facing feature is next.
Kavita
6.3COLLAB
Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.
◆ Current state
Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.
◆ Where it's heading
The Kavita+ overhaul repositions the premium tier from a metadata downloader into a connected reading ecosystem. Hardcover integration is the first external service partnership for Kavita+, suggesting the project is moving beyond a standalone reader toward a recommendation and discovery layer. The recurring pattern of epub reader and reading experience improvements reflects a platform that has matured past basic library management.
◆ Prediction
Kavita will deepen the Hardcover integration with additional recommendation signals and expand Kavita+ to include connections to other reading platforms — likely Anilist or similar — as the subscription layer evolves from metadata tools to a reading discovery platform.
