EGroupware vs Komga
A side-by-side editorial comparison of EGroupware and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
EGroupware vs Komga: at a glance
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.
What is Komga?
A mature media server whose releases are format edge cases and Kobo plumbing.
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.

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.
Komga
0.0COLLAB
A mature media server whose releases are format edge cases and Kobo plumbing.
◆ Current state
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.
◆ Where it's heading
The work concentrates where a self-hosted library server actually breaks: malformed EPUBs, archive formats readers assume will just open, and the sync protocols third-party devices speak. Kobo integration keeps taking attention — content restriction enforcement, proxying raw request bodies to the Kobo store — which suggests e-reader compatibility is where the user pressure sits. Translation batches from Weblate appear in most releases.
◆ Prediction
Expect more format-tolerance work on EPUB and archive handling, with the Kobo and KOReader integrations continuing to absorb the fixes that a mature library server accumulates.
