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 moves builds to Python 3.14 and Ubuntu 26.04 by default.
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
What is SiYuan?
SiYuan's third 3.8.10 alpha adds a built-in Markdown editor and video looping.
SiYuan opened the 3.8.10 line on Oct 31 with workspace-level long-term memory for AI, database sub-items, HTTP requests in templates and an Exa key for built-in web search. Alpha.3 on Nov 2 grows the list to 19 items, adding a built-in lightweight Markdown editor, loop playback for video blocks, configurable floating dock visibility and a command-line switch for the fixed-port proxy. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.

Read the Docs
5.0COLLAB
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
◆ Current state
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
◆ Where it's heading
Two threads run through the releases: a direct upload path for docs built elsewhere, which has had design docs, workflows and onboarding in September and October, and steady hardening of the build platform. Most entries are still lists of merged PRs with dependency bumps.
◆ Prediction
Expect direct upload to move toward general availability and more GitHub App defaults replacing the OAuth app.
SiYuan
5.0COLLAB
SiYuan's third 3.8.10 alpha adds a built-in Markdown editor and video looping.
◆ Current state
SiYuan opened the 3.8.10 line on Oct 31 with workspace-level long-term memory for AI, database sub-items, HTTP requests in templates and an Exa key for built-in web search. Alpha.3 on Nov 2 grows the list to 19 items, adding a built-in lightweight Markdown editor, loop playback for video blocks, configurable floating dock visibility and a command-line switch for the fixed-port proxy. No stable 3.8.9 appears in the feed, so rc.1 is the last visible milestone for that line.
◆ Where it's heading
SiYuan runs fast alpha and beta cycles where each build extends a cumulative list. The AI agent and databases get the larger features, while editor and mobile items fill the rest.
◆ Prediction
Expect more 3.8.10 alphas with a growing list before a beta; whether 3.8.9 ships as stable first is unclear from the feed.
