SiYuan vs Lidarr
A side-by-side editorial comparison of SiYuan and Lidarr — release velocity, themes, recent moves, and the top alternatives to consider.
SiYuan vs Lidarr: at a glance
What is SiYuan?
SiYuan's 3.8 branch turns a local-first notebook into an agent-readable knowledge store.
SiYuan publishes near-daily alpha tags whose notes are cumulative, so each release restates the previous one's feature list and appends what is new. The 3.7.4 line was pure enhancement work — Android and HarmonyOS parity, export fidelity, Pandoc packaging, drag-and-drop and font handling. The 3.8.0 line, opened on 4 August, carries four genuinely new features that had no predecessor in 3.7.4: OIDC authentication, an AI Agent, semantic search via embeddings and reranking, and MCP support.
What is Lidarr?
Lidarr's release notes still tell you not to update Radarr — the fork's seams are showing.
Lidarr publishes auto-generated pre-release builds every few weeks, each carrying a handful of commits. The recent ones add rate limiting to Spotify lookup endpoints, fix basic auth and cookie reuse for qBittorrent, pull in Weblate translation updates and bump ImageSharp and MailKit. The boilerplate at the top of every entry warns against updating Radarr inside an existing container — text inherited from the upstream project and never changed.

SiYuan
6.3COLLAB
SiYuan's 3.8 branch turns a local-first notebook into an agent-readable knowledge store.
◆ Current state
SiYuan publishes near-daily alpha tags whose notes are cumulative, so each release restates the previous one's feature list and appends what is new. The 3.7.4 line was pure enhancement work — Android and HarmonyOS parity, export fidelity, Pandoc packaging, drag-and-drop and font handling. The 3.8.0 line, opened on 4 August, carries four genuinely new features that had no predecessor in 3.7.4: OIDC authentication, an AI Agent, semantic search via embeddings and reranking, and MCP support.
◆ Where it's heading
The mobile and export grind continues underneath, but the branch cut is where the direction changed. Semantic search plus MCP means the vault becomes queryable by meaning and reachable by external agents, while OIDC is the first real answer for multi-user or organizational deployment — a notable turn for a product built around single-user local storage. The alpha.3 addition of LAN peer-assisted sync acceleration points the same way: sync is being optimized for several devices, or several people, on one network.
◆ Prediction
Expect the 3.8 alphas to keep layering onto the AI Agent and MCP surfaces — most likely which blocks or notebooks an agent may read, since OIDC arriving in the same release implies identity is about to gate access rather than just login.
Lidarr
5.0COLLAB
Lidarr's release notes still tell you not to update Radarr — the fork's seams are showing.
◆ Current state
Lidarr publishes auto-generated pre-release builds every few weeks, each carrying a handful of commits. The recent ones add rate limiting to Spotify lookup endpoints, fix basic auth and cookie reuse for qBittorrent, pull in Weblate translation updates and bump ImageSharp and MailKit. The boilerplate at the top of every entry warns against updating Radarr inside an existing container — text inherited from the upstream project and never changed.
◆ Where it's heading
This is a project maintained rather than developed. Version numbers advance through build counts more than features, one release in this window contains nothing but a version bump, and the substantive work is defensive: staying within third-party rate limits, keeping torrent client authentication working, absorbing dependency updates. The metadata providers it depends on are where the pressure shows.
◆ Prediction
Expect continued small builds driven by external breakage — torrent client authentication changes and metadata provider limits are the two recurring sources here. The rate limiting added for Spotify suggests provider throttling is an active problem, so more of the same is the likeliest next move.
