Komga vs Wiki.js
A side-by-side editorial comparison of Komga and Wiki.js — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:self-hosted
Komga vs Wiki.js: at a glance
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.
What is Wiki.js?
Wiki.js 2.x is in security-maintenance mode, and the feed has been quiet since May
Six patch releases on the 2.5 line, most of them fixes. The substantive ones are security: a permissions flaw allowing user assignment to elevated groups, open redirect validation on the login redirect cookie, authentication for GraphQL subscription WebSocket connections, prototype pollution in Rocket.Chat auth, and secure cookie flags on HTTPS sites. Two small features appear — OIDC and OAuth2 avatar claim mapping, and MySQL socket path connections.

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.

Wiki.js 2.x is in security-maintenance mode, and the feed has been quiet since May
◆ Current state
Six patch releases on the 2.5 line, most of them fixes. The substantive ones are security: a permissions flaw allowing user assignment to elevated groups, open redirect validation on the login redirect cookie, authentication for GraphQL subscription WebSocket connections, prototype pollution in Rocket.Chat auth, and secure cookie flags on HTTPS sites. Two small features appear — OIDC and OAuth2 avatar claim mapping, and MySQL socket path connections.
◆ Where it's heading
This is a mature 2.x line receiving externally reported vulnerability fixes and community contributions rather than product direction. Several fixes credit outside researchers and contributors, which is what maintenance looks like when the maintainer's attention is elsewhere. Release intervals stretched from days in January to nothing since early May.
◆ Prediction
More 2.5.x patches driven by reported vulnerabilities are the likely continuation. Nothing in this window indicates when feature work resumes.
