Kavita vs Rocket.Chat: at a glance
What is Kavita?
A self-hosted reading server that spent two releases becoming infrastructure, then paid for it with a CVE.
Kavita ships two to four substantial releases a year with hotfixes trailing each one, and the last two years moved it well past a comic reader: OIDC login, an annotation system, a rebuilt epub reader, a reading-list overhaul, a stats system, and a scanner reported 50x faster. The most recent release is a critical security hotfix carrying CVE-2026-47202 that affects every prior version. Kavita+ remains the paid tier where metadata features land first.
What is Rocket.Chat?
A long RC train of dependency bumps, with the real work landing in the 8.7 branch opener.
Rocket.Chat publishes every release candidate, and the shape is consistent: the .rc.0 that opens a minor carries the substance, and every RC after it is a Meteor version bump with the occasional fix. The 8.7 line opened with server-side OAuth, PKCE and state validation under a phishing-resistant MFA banner, plus session identification in device management. The four RCs since have added one user-visible fix — seekable audio attachments.

Kavita
0.0COLLAB
A self-hosted reading server that spent two releases becoming infrastructure, then paid for it with a CVE.
◆ Current state
Kavita ships two to four substantial releases a year with hotfixes trailing each one, and the last two years moved it well past a comic reader: OIDC login, an annotation system, a rebuilt epub reader, a reading-list overhaul, a stats system, and a scanner reported 50x faster. The most recent release is a critical security hotfix carrying CVE-2026-47202 that affects every prior version. Kavita+ remains the paid tier where metadata features land first.
◆ Where it's heading
The arc is a hobby-scale project taking on the obligations of infrastructure — standard auth, an external API contract for third-party clients, sync with other readers, and formal vulnerability disclosure. Each of those decisions expands the attack surface, and the 0.9.x line shows the bill arriving: security hardening now leads the release notes rather than following them. The team has also visibly grown from one maintainer to a named pair, which is what made the parallel reader and foundation rewrites possible.
◆ Prediction
The next release is likely the delayed scanner-improvement work that 0.8.7 displaced, with continued API hardening rather than new reader surfaces. Expect the CVE details to be published once adoption of 0.9.0.2 is high enough.
Rocket.Chat
6.3COLLAB
A long RC train of dependency bumps, with the real work landing in the 8.7 branch opener.
◆ Current state
Rocket.Chat publishes every release candidate, and the shape is consistent: the .rc.0 that opens a minor carries the substance, and every RC after it is a Meteor version bump with the occasional fix. The 8.7 line opened with server-side OAuth, PKCE and state validation under a phishing-resistant MFA banner, plus session identification in device management. The four RCs since have added one user-visible fix — seekable audio attachments.
◆ Where it's heading
The feature direction is enterprise and regulated deployment: phishing-resistant authentication in 8.7, attribute-based access control with an external Virtru attribute store in 8.6, federation and personal-access-token correctness fixes throughout. These are the requirements of buyers who run Rocket.Chat themselves because they cannot use a hosted competitor, and the release notes read like a queue of their procurement checklists.
◆ Prediction
Expect 8.7 to reach general availability with the OAuth rework as its headline and little added beyond it, since the RC train has been quiet since rc.0. The unified presence engine whose backend landed in 8.6 has no user-facing surface yet, making it the likeliest candidate for the next minor.
