Kavita vs EGroupware: 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 EGroupware?
EGroupware is pushing its old branch off a cliff on 15 August, and sweetening the landing with passkeys.
Releases arrive in pairs — one for the 23.1 branch, one for the current 26.x — usually within minutes of each other and usually flagged SECURITY. The 23.1 notes have carried an end-of-support warning for weeks; coverage stops on 15 August 2026. The 26.x side of each pair carries the actual product work: WebAuthN as a second factor, CalDAV timezone and recurrence fixes, invoice XML exemption codes, OpenID library upgrades.

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.
EGroupware
6.3COLLAB
EGroupware is pushing its old branch off a cliff on 15 August, and sweetening the landing with passkeys.
◆ Current state
Releases arrive in pairs — one for the 23.1 branch, one for the current 26.x — usually within minutes of each other and usually flagged SECURITY. The 23.1 notes have carried an end-of-support warning for weeks; coverage stops on 15 August 2026. The 26.x side of each pair carries the actual product work: WebAuthN as a second factor, CalDAV timezone and recurrence fixes, invoice XML exemption codes, OpenID library upgrades.
◆ Where it's heading
The pattern is a forced migration executed through security cadence rather than announcement. Each paired release makes the gap wider: 23.1 receives the fix, 26.x receives the fix plus features, and the deadline text repeats. Underneath, the substantive work is authentication — WebAuthN, OpenID Connect verification fixes, email_verified handling — for a self-hosted suite whose buyers care about exactly that.
◆ Prediction
Expect one or two more 23.1 security releases before 15 August and then nothing, with the paired-release rhythm collapsing to a single 26.x train afterwards.
