Capacities vs Komga
A side-by-side editorial comparison of Capacities and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
Capacities vs Komga: at a glance
What is Capacities?
Capacities adds whiteboards and a global graph to its object-based notes.
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
What is Komga?
Komga's NextUI beta keeps gaining features while the old UI gets only translations.
Komga ships every one to two weeks, and almost all feature work lands in NextUI, the rewritten web interface served at /next. The third NextUI beta in 1.28.0 added contextual navigation, such as moving between books in a series or read list, and 1.29.0 added Notable Entities metadata that only NextUI shows. The latest patches fix page counts and KOReader hashes and carry dependency and translation updates.
Capacities vs Komga: editorial side-by-side
Capacities
2.5COLLAB
Capacities adds whiteboards and a global graph to its object-based notes.
◆ Current state
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
◆ Where it's heading
Two threads run together: AI that acts inside the workspace (connectors, chats that edit, a paid AI budget) and better ways to see and capture what is already stored (graph, whiteboards, audio). API 2.0 in July opened the space to outside tools.
◆ Prediction
Expect more AI actions inside chats and further work on the graph and whiteboard surfaces; the entries do not say whether whiteboards will reach the API.
Komga
5.0COLLAB
Komga's NextUI beta keeps gaining features while the old UI gets only translations.
◆ Current state
Komga ships every one to two weeks, and almost all feature work lands in NextUI, the rewritten web interface served at /next. The third NextUI beta in 1.28.0 added contextual navigation, such as moving between books in a series or read list, and 1.29.0 added Notable Entities metadata that only NextUI shows. The latest patches fix page counts and KOReader hashes and carry dependency and translation updates.
◆ Where it's heading
NextUI is moving from preview to the main interface: each minor release adds features exclusive to it, and the old web UI now receives only translations and dependency bumps. The server side keeps adding API checks and Kobo sync fixes underneath.
◆ Prediction
Expect further NextUI betas with editing and navigation features, and eventually a release that makes NextUI the default; the entries don't give a date.
