Komga vs Tana
A side-by-side editorial comparison of Komga and Tana — release velocity, themes, recent moves, and the top alternatives to consider.
Komga vs Tana: 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 Tana?
The knowledge graph quietly turned itself into a meetings product.
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.

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.
Tana
6.3COLLAB
The knowledge graph quietly turned itself into a meetings product.
◆ Current state
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.
◆ Where it's heading
Tana is moving from a tool that stores what happened in a meeting to one that runs the meeting. Native Tana calls are now the default path on Today, with Zoom, Meet and Teams demoted to a capture case handled through desktop audio. The agent work points the same way: voices for meeting agents, AI that acts immediately rather than proposing changes for approval. The graph is becoming the substrate rather than the interface.
◆ Prediction
Given the pace of meeting-surface work and the AI moving from proposals to direct action, the next step is most likely deepening what agents can do during a live call. Nothing in these entries indicates how the token optimisation affects the underlying usage limits.
