Komga vs PhotoPrism: 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 PhotoPrism?
PhotoPrism now lets AI assistants search your photo library over MCP.
PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.
Komga vs PhotoPrism: editorial side-by-side
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.
PhotoPrism
6.3COLLAB
PhotoPrism now lets AI assistants search your photo library over MCP.
◆ Current state
PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.
◆ Where it's heading
The vision stack is now fully ONNX and GPU-capable, and the library itself is becoming something other tools can query. PostgreSQL support breaks the long MariaDB/SQLite limit for larger installs.
◆ Prediction
PostgreSQL leaving experimental status and MCP gaining more than read-only search are the likely next steps, given both arrived in first form here.
