File Browser vs Kavita: at a glance
What is File Browser?
File Browser is shutting down — the repo archives on 2026-09-01 and no security fixes follow.
The project spent July shipping a rapid series of hardening releases — path canonicalization before access checks, atomic user provisioning, TUS upload length enforcement, download-permission gates, case-folded home directory collisions, several GHSA-tracked share and auth advisories — and then announced it was winding down. 2.63.23 is the last planned release; the repository archives on 2026-09-01.
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.

File Browser is shutting down — the repo archives on 2026-09-01 and no security fixes follow.
◆ Current state
The project spent July shipping a rapid series of hardening releases — path canonicalization before access checks, atomic user provisioning, TUS upload length enforcement, download-permission gates, case-folded home directory collisions, several GHSA-tracked share and auth advisories — and then announced it was winding down. 2.63.23 is the last planned release; the repository archives on 2026-09-01.
◆ Where it's heading
The shape of the final weeks tells the story: almost every commit was a scope-escape or permission-bypass fix, which is a heavy load for a Go binary that many people expose directly to the internet. Rather than keep absorbing that, the maintainers are stopping. Existing releases and Docker images stay online, but from September there is no one fixing the next advisory.
◆ Prediction
Existing deployments keep working and keep accumulating unpatched vulnerabilities; expect the community to consolidate around a fork or one of the existing alternatives before the archive date.

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.
