What is Shiori?

A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.

Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.

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.

A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.

◆ Current state

Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.

◆ Where it's heading

The project is converting from a web app with an API bolted on into an API-first service with a client, and the login component, PWA and theme work are being rewritten around that split. Proxy forward-header authentication in particular is a deployment-shape decision: it assumes Shiori sits behind an authenticating reverse proxy rather than owning identity itself. The RC-only tagging pattern makes it hard to tell what the maintainers consider stable.

◆ Prediction

The next step is presumably a final v1.8.0 consolidating the API v1 tag work, though nothing in these entries indicates the RC-to-stable promotion is scheduled. If the pattern holds, the following RC continues on API endpoints rather than the UI.

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.
