Komga vs Paperless-ngx: at a glance
What is Komga?
Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.
What is Paperless-ngx?
Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.
3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
◆ Current state
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.
◆ Where it's heading
The project is running a long, deliberately cautious frontend migration: both UIs ship in the same binary, the feature gap is tracked publicly in an issue, and users opt in by URL. That arrangement should persist across several minor versions before the old WebUI is retired. The parallel v2 referential API suggests the rewrite is also being used to revise the server contract rather than only restyle the client.
◆ Prediction
Near-term releases should keep closing the NextUI feature gap issue by issue, with patch releases landing within days of each other. The old WebUI is unlikely to be removed before NextUI reaches parity and browser refresh stops falling back to it.

6.3COLLAB
Paperless-ngx shipped its 3.0 rewrite, then spent a week putting out the fires.
◆ Current state
3.0.0 landed on July 22 after a long beta, carrying both the largest feature set in the project's history and nine breaking changes. The five releases since are pure repair: a broken migration in 3.0.1 that forced an immediate 3.0.2, then three patch rounds covering OCR skipping, permission-filtered dedup, Gotenberg conversion, email date parsing, AI suggestion caching and search index edge cases. The pace tells you 3.0 shipped into real deployments fast.
◆ Where it's heading
The project has moved from a document scanner-and-tagger to a document platform with AI in the core: Paperless AI, remote OCR via Azure, a document parser plugin framework, tantivy replacing Whoosh for search, file versions and sharelink bundles. The breaking changes are the other half of that story — dropping API v1, Python 3.10, document encryption and the old consumer clears the decks for that platform. Recent patches keep touching LLM plumbing, including passing output language into chat and adding docstrings so the classifier reads better as an LLM tool.
◆ Prediction
The 3.0.x patch cadence looks set to run at least another round or two — 3.0.5 is still landing search-compatibility and AI-suggestion fixes rather than tapering. Feature work resuming before that queue empties would be the surprise.
