Paperless-ngx vs Kavita: at a glance
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.
What is Kavita?
A self-hosted reading server that spent two releases becoming infrastructure, then paid for it with a CVE.
Kavita ships two to four substantial releases a year with hotfixes trailing each one, and the last two years moved it well past a comic reader: OIDC login, an annotation system, a rebuilt epub reader, a reading-list overhaul, a stats system, and a scanner reported 50x faster. The most recent release is a critical security hotfix carrying CVE-2026-47202 that affects every prior version. Kavita+ remains the paid tier where metadata features land first.

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.
Kavita
0.0COLLAB
A self-hosted reading server that spent two releases becoming infrastructure, then paid for it with a CVE.
◆ Current state
Kavita ships two to four substantial releases a year with hotfixes trailing each one, and the last two years moved it well past a comic reader: OIDC login, an annotation system, a rebuilt epub reader, a reading-list overhaul, a stats system, and a scanner reported 50x faster. The most recent release is a critical security hotfix carrying CVE-2026-47202 that affects every prior version. Kavita+ remains the paid tier where metadata features land first.
◆ Where it's heading
The arc is a hobby-scale project taking on the obligations of infrastructure — standard auth, an external API contract for third-party clients, sync with other readers, and formal vulnerability disclosure. Each of those decisions expands the attack surface, and the 0.9.x line shows the bill arriving: security hardening now leads the release notes rather than following them. The team has also visibly grown from one maintainer to a named pair, which is what made the parallel reader and foundation rewrites possible.
◆ Prediction
The next release is likely the delayed scanner-improvement work that 0.8.7 displaced, with continued API hardening rather than new reader surfaces. Expect the CVE details to be published once adoption of 0.9.0.2 is high enough.
