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 Readwise?

Readwise splits its bundle into Reader-only and Highlights-only plans and renames its first app.

Readwise posts a weekly changelog. The October 23 release changes packaging: the original app is now Readwise Highlights, and users can subscribe to Reader or Highlights alone instead of the full bundle, switching plans themselves. The same week adds 38 Lifelike beta voices in 14 languages, rebuilds Daily Review audio on those voices, and makes YouTube transcripts twice as fast without filler words.

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.

6.3

Readwise splits its bundle into Reader-only and Highlights-only plans and renames its first app.

◆ Current state

Readwise posts a weekly changelog. The October 23 release changes packaging: the original app is now Readwise Highlights, and users can subscribe to Reader or Highlights alone instead of the full bundle, switching plans themselves. The same week adds 38 Lifelike beta voices in 14 languages, rebuilds Daily Review audio on those voices, and makes YouTube transcripts twice as fast without filler words.

◆ Where it's heading

Reader has been the main product thread for months (TTS, Ghostreader on GPT-6 Luna, video transcripts), and the plan split lets it be sold on its own. Lifelike voices are spreading from Reader's Listen into Highlights' Daily Review, so the two apps now share an audio layer while being priced separately.

◆ Prediction

Expect follow-up fixes around plan switching and more Lifelike voice tuning; Lifelike leaving beta is the most supported next feature step.
