Read the Docs vs SiYuan
A side-by-side editorial comparison of Read the Docs and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
Read the Docs vs SiYuan: at a glance
What is Read the Docs?
Read the Docs deploys weekly, and almost all of it is rebuilding how builds run.
Read the Docs cuts a dated release every week, most of them thin — a dependency sweep, a docs correction, a CI bump. The substance in this window is concentrated in the build platform: ephemeral builders moving from experiment to implementation, uv installed and configured for generic builders, private-repo permissions plumbed through to the isolated builder, and a hardened tar extraction filter when unpacking doctools.
What is SiYuan?
SiYuan's 3.8 alpha turns the note vault into an agent surface: embeddings, reranking, MCP.
SiYuan runs a rolling alpha train in which each release restates the cumulative changelog of the one before it, so the feed reads as repetition unless you track first appearances. The 3.7.4 alphas were a long run of platform polish — Android and HarmonyOS audio recording, S Pen hover on tablets, mobile font import, sync performance, drag-and-drop cues. Then 3.8.0-alpha.1 opened a new block with three things absent from that line: OIDC authentication, an AI Agent with embedding-based semantic search and reranking, and Model Context Protocol support.

Read the Docs
5.0COLLAB
Read the Docs deploys weekly, and almost all of it is rebuilding how builds run.
◆ Current state
Read the Docs cuts a dated release every week, most of them thin — a dependency sweep, a docs correction, a CI bump. The substance in this window is concentrated in the build platform: ephemeral builders moving from experiment to implementation, uv installed and configured for generic builders, private-repo permissions plumbed through to the isolated builder, and a hardened tar extraction filter when unpacking doctools.
◆ Where it's heading
The through-line is the build layer being re-founded on isolation and speed. Ephemeral builders, an isolated builder that receives permissions explicitly rather than inheriting them, and uv replacing the older Python environment path all point at builds that start faster and share less. Around that, the product-facing changes are small and mostly clarifying: renaming External versions to Pull request in the interface, distinct commit statuses for skipped builds, a dropdown instead of free text when filtering redirects.
◆ Prediction
Ephemeral builders moved from a test to real wiring across these releases, so the next step is most likely rolling that path out more widely and continuing the uv migration, rather than user-facing feature work.
SiYuan
6.3COLLAB
SiYuan's 3.8 alpha turns the note vault into an agent surface: embeddings, reranking, MCP.
◆ Current state
SiYuan runs a rolling alpha train in which each release restates the cumulative changelog of the one before it, so the feed reads as repetition unless you track first appearances. The 3.7.4 alphas were a long run of platform polish — Android and HarmonyOS audio recording, S Pen hover on tablets, mobile font import, sync performance, drag-and-drop cues. Then 3.8.0-alpha.1 opened a new block with three things absent from that line: OIDC authentication, an AI Agent with embedding-based semantic search and reranking, and Model Context Protocol support.
◆ Where it's heading
The 3.7.4 line was about making an existing editor pleasant on more devices; 3.8.0 is about making the vault legible to something other than a human. Semantic search over the note graph plus an MCP server positions the personal knowledge base as a context source for external agents, and OIDC landing in the same release suggests the multi-user and self-hosted deployments that make agent access worth governing. The alpha train will keep restating this block verbatim until 3.8.0 stabilizes, so the feed will understate how much has changed.
◆ Prediction
The AI Agent and MCP features will likely accumulate configuration surface across the remaining 3.8.0 alphas — model and embedding-provider choice, and scoping of which notebooks an agent may read — before a stable release.
