EGroupware vs Komga: at a glance
What is EGroupware?
EGroupware's feed has become a security treadmill, with the 23.1 branch days from end of life.
Almost every release in this window is a security release, and most ship as a pair — one build for 26.x, an identical-scope backport for 23.1. Feature work exists but arrives as single lines inside those security notes: WebAuthN two-factor moving out of the former EPL add-on, OpenID bumped to current upstream libraries, invoice XML gaining reverse-charge exemption codes. The recurring theme in the fixes themselves is authentication — OAuth bearer tokens, OpenID regressions, an inverted email_verified check, passkeys broken by a missing proxy config.
What is Komga?
Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.

EGroupware
5.0COLLAB
EGroupware's feed has become a security treadmill, with the 23.1 branch days from end of life.
◆ Current state
Almost every release in this window is a security release, and most ship as a pair — one build for 26.x, an identical-scope backport for 23.1. Feature work exists but arrives as single lines inside those security notes: WebAuthN two-factor moving out of the former EPL add-on, OpenID bumped to current upstream libraries, invoice XML gaining reverse-charge exemption codes. The recurring theme in the fixes themselves is authentication — OAuth bearer tokens, OpenID regressions, an inverted email_verified check, passkeys broken by a missing proxy config.
◆ Where it's heading
The project is consolidating everyone onto 26.x and has put a date on it: security coverage for 23.1 ends August 15, 2026, repeated as a warning in every 23.1 build since July. After that the twin-release pattern should stop and the cadence should halve. The authentication stack is the least settled part of the codebase right now — the July and August releases keep re-fixing OpenID and WebAuthN regressions introduced by their own predecessors.
◆ Prediction
Expect 23.1 builds to cease after August 15 and the feed to become single-track 26.x. On the evidence of the last six releases, expect at least one more OpenID or WebAuthN regression fix to follow the recent upstream library bump.
Komga
6.3COLLAB
Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
◆ Current state
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.
◆ Where it's heading
The project is running a long, deliberately cautious frontend migration: both UIs ship in the same binary, the feature gap is tracked publicly in an issue, and users opt in by URL. That arrangement should persist across several minor versions before the old WebUI is retired. The parallel v2 referential API suggests the rewrite is also being used to revise the server contract rather than only restyle the client.
◆ Prediction
Near-term releases should keep closing the NextUI feature gap issue by issue, with patch releases landing within days of each other. The old WebUI is unlikely to be removed before NextUI reaches parity and browser refresh stops falling back to it.
