ArchivesSpace vs Komga
A side-by-side editorial comparison of ArchivesSpace and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
ArchivesSpace vs Komga: at a glance
What is ArchivesSpace?
An archives platform whose big releases are infrastructure debt being paid down
ArchivesSpace publishes release candidates rather than a continuous stream, and the two substantive entries here bracket its recent history. v4.0.0-RC1 was an infrastructure release — Bootstrap, Rails, JRuby, jQuery and Jetty all moved forward, the staff CSS migrated from less to sass, and specs were ported to capybara. v4.2.0-RC1 is the opposite in scale: bug fixes plus small configurable options for the staff and public interfaces.
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.

◆ Current state
ArchivesSpace publishes release candidates rather than a continuous stream, and the two substantive entries here bracket its recent history. v4.0.0-RC1 was an infrastructure release — Bootstrap, Rails, JRuby, jQuery and Jetty all moved forward, the staff CSS migrated from less to sass, and specs were ported to capybara. v4.2.0-RC1 is the opposite in scale: bug fixes plus small configurable options for the staff and public interfaces.
◆ Where it's heading
The pattern is a maintained institutional application, not a product chasing new capability. The 4.0 work was explicitly framed as changes users would barely notice but that unblock future development, and 4.2 spends its budget on the specific friction archivists hit — mobile PDF downloads, setting users inactive, controlling which fields carry over when duplicating a resource. Configuration options rather than features is the recurring shape.
◆ Prediction
Expect 4.2.0 to reach a final release with the RC contents intact, and subsequent releases to continue mixing small interface fixes with periodic dependency modernization.

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.
