Komga vs Shiori: 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 Shiori?
A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.

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.
Shiori
0.0COLLAB
A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.
◆ Current state
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.
◆ Where it's heading
The project is converting from a web app with an API bolted on into an API-first service with a client, and the login component, PWA and theme work are being rewritten around that split. Proxy forward-header authentication in particular is a deployment-shape decision: it assumes Shiori sits behind an authenticating reverse proxy rather than owning identity itself. The RC-only tagging pattern makes it hard to tell what the maintainers consider stable.
◆ Prediction
The next step is presumably a final v1.8.0 consolidating the API v1 tag work, though nothing in these entries indicates the RC-to-stable promotion is scheduled. If the pattern holds, the following RC continues on API endpoints rather than the UI.
