Komga vs Paperless-ngx: at a glance
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.
What is Paperless-ngx?
Paperless-ngx shipped seven releases in October, two of them for security
Paperless-ngx ran from 3.3.0 to 3.4.1 in October. 3.3.0 added stored barcode contents and more control over LLM requests, 3.3.2 fixed a reported security issue, and 3.3.4 updated dependencies for the eMudhra CA incident plus Pillow and aiohttp vulnerabilities. 3.4.0 brought custom fields in workflow title templates, relative-date custom field queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. The other releases were fixes, many around document versions and search.

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.
Paperless-ngx
5.0COLLAB
Paperless-ngx shipped seven releases in October, two of them for security
◆ Current state
Paperless-ngx ran from 3.3.0 to 3.4.1 in October. 3.3.0 added stored barcode contents and more control over LLM requests, 3.3.2 fixed a reported security issue, and 3.3.4 updated dependencies for the eMudhra CA incident plus Pillow and aiohttp vulnerabilities. 3.4.0 brought custom fields in workflow title templates, relative-date custom field queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. The other releases were fixes, many around document versions and search.
◆ Where it's heading
The AI features introduced in 3.x are being refined rather than expanded, while workflows and search get steady quality-of-life work.
◆ Prediction
Another 3.4.x patch for UI regressions is likely, following the 3.3.x pattern of several fix releases after each minor.
