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.

What is SiYuan?

SiYuan opened a 3.8 branch and put AI agents, embeddings search and MCP in the first alpha.

The 3.7.4 alpha series ran as pure enhancement work with cumulative notes — each alpha restates the previous list and adds a line or two — covering mobile and HarmonyOS parity, database view refinements, drag-and-drop polish, and sync performance. The first 3.8 alpha breaks that pattern with a Feature block: secure OIDC authentication, an AI Agent, semantic search using embeddings and reranking, and Model Context Protocol support.

Kavita vs SiYuan: editorial side-by-side

Kavita
COLLAB
0.0

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.

6.3

SiYuan opened a 3.8 branch and put AI agents, embeddings search and MCP in the first alpha.

◆ Current state

The 3.7.4 alpha series ran as pure enhancement work with cumulative notes — each alpha restates the previous list and adds a line or two — covering mobile and HarmonyOS parity, database view refinements, drag-and-drop polish, and sync performance. The first 3.8 alpha breaks that pattern with a Feature block: secure OIDC authentication, an AI Agent, semantic search using embeddings and reranking, and Model Context Protocol support.

◆ Where it's heading

Two years of this changelog have been editor and database ergonomics for a local-first note tool. The 3.8 opening moves the product into retrieval and agent territory in one step, and pairs it with OIDC — which suggests the target is shared or self-hosted deployments, not just single-user vaults. The mobile and HarmonyOS work continues underneath.

◆ Prediction

Expect the 3.8 alpha series to spend several releases stabilising the embedding and MCP surface, with the practical questions — which models, local or remote, and what leaves the vault — resolved in later alphas rather than this one.
