BookStack vs Komga: at a glance
What is BookStack?
BookStack's first feature release since May requires an APP_KEY and needed two quick patches
After four months of security patches on the 26.05 line, BookStack shipped v26.09 in late September: an interface layout system with theme support, API search within a book or chapter, a page scroll indicator, changelog messages on page API writes, and password changes that require the current password. It also stopped falling back to a default APP_KEY. Two patches followed within a month, one checking ZIP imports' real uncompressed size and one fixing comment and attachment exposure around the recycle bin and drafts.
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.

◆ Current state
After four months of security patches on the 26.05 line, BookStack shipped v26.09 in late September: an interface layout system with theme support, API search within a book or chapter, a page scroll indicator, changelog messages on page API writes, and password changes that require the current password. It also stopped falling back to a default APP_KEY. Two patches followed within a month, one checking ZIP imports' real uncompressed size and one fixing comment and attachment exposure around the recycle bin and drafts.
◆ Where it's heading
Security hardening keeps setting the cadence even after a feature release, with researcher reports credited in most patches. The new layout system opens the UI to customization through the theme system.
◆ Prediction
Further 26.09.x security releases are likely given the steady run of researcher reports; the entries give no date for the next feature release.
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.
