Conceptboard vs Komga
A side-by-side editorial comparison of Conceptboard and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
Conceptboard vs Komga: at a glance
What is Conceptboard?
Conceptboard ships sparingly; Smart sections brings hierarchy and real accessibility to the canvas
Conceptboard ships infrequently, with long gaps between releases and mostly small canvas refinements. The latest and most substantive addition is Smart sections, which adds hierarchical organization to large boards with full keyboard navigation and screen-reader support. Earlier 2026 work was limited to cloud-storage integrations and minor copying and styling tweaks.
What is Komga?
After two years of quiet fixes, Komga puts a whole new web UI in front of users.
Komga's recent history is almost entirely maintenance — archive-format edge cases, EPUB table-of-contents parsing, Kobo and OPDS compatibility, and a long tail of dependency bumps and translations. Release 1.26.0 breaks that pattern by shipping NextUI, a rewritten web interface, in beta and served alongside the existing one from the same server. The old UI remains the default, and the new one is reached from a sidebar link or a /next path, with a published list of what is still missing.

Conceptboard ships sparingly; Smart sections brings hierarchy and real accessibility to the canvas
◆ Current state
Conceptboard ships infrequently, with long gaps between releases and mostly small canvas refinements. The latest and most substantive addition is Smart sections, which adds hierarchical organization to large boards with full keyboard navigation and screen-reader support. Earlier 2026 work was limited to cloud-storage integrations and minor copying and styling tweaks.
◆ Where it's heading
The pace is slow and the changes incremental, but accessibility is an emerging emphasis, with Smart sections leading on keyboard navigation and screen-reader descriptions for canvas content. Cloud integrations and visual customization round out the recent work. The direction reads as steady refinement of the existing whiteboard rather than expansion.
◆ Prediction
Expect continued low-frequency releases focused on canvas usability and accessibility, possibly with more board-organization and integration features. The sparse cadence makes a confident near-term call difficult.
Komga
6.3COLLAB
After two years of quiet fixes, Komga puts a whole new web UI in front of users.
◆ Current state
Komga's recent history is almost entirely maintenance — archive-format edge cases, EPUB table-of-contents parsing, Kobo and OPDS compatibility, and a long tail of dependency bumps and translations. Release 1.26.0 breaks that pattern by shipping NextUI, a rewritten web interface, in beta and served alongside the existing one from the same server. The old UI remains the default, and the new one is reached from a sidebar link or a /next path, with a published list of what is still missing.
◆ Where it's heading
This is a staged frontend replacement rather than a cutover: two UIs on one web server, a v2 referential API landing in the same release to back the new client, and a hotfix a few hours later for NextUI CSS layers under Tomcat. The backend is simplifying in parallel — RAR5 support moved to plain Java and libarchive was dropped from the Docker image and the tray app, removing a native dependency from the build. Feature work outside the UI stays narrow and format-focused.
◆ Prediction
Expect a run of point releases closing the gaps in NextUI's feature list and hardening the two-UI serving path, with the beta label staying on until parity is reached. A default switch is unlikely before the missing features land.
