Flarum vs SiYuan
A side-by-side editorial comparison of Flarum and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
Flarum vs SiYuan: at a glance
What is Flarum?
Flarum's 2.0 candidates are accelerating, but the feed publishes only a link per tag.
Flarum is eight release candidates into 2.0, with rc.6, rc.7, and rc.8 landing within five days after a gap of roughly seven weeks following rc.5. The feed carries no notes: each entry is a single line pointing at the CHANGELOG.md for that tag, so the content of these candidates is not visible here. The last entry with substantive text was rc.1 in April, which addressed discussion-list and notification query costs.
What is SiYuan?
SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.
SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Flarum
5.0COLLAB
Flarum's 2.0 candidates are accelerating, but the feed publishes only a link per tag.
◆ Current state
Flarum is eight release candidates into 2.0, with rc.6, rc.7, and rc.8 landing within five days after a gap of roughly seven weeks following rc.5. The feed carries no notes: each entry is a single line pointing at the CHANGELOG.md for that tag, so the content of these candidates is not visible here. The last entry with substantive text was rc.1 in April, which addressed discussion-list and notification query costs.
◆ Where it's heading
Tempo is the only signal this feed supports, and it has clearly changed: three candidates in five days after seven quiet weeks reads as convergence on a final rather than continued development. What is actually changing between candidates cannot be determined from this source without following the linked changelog.
◆ Prediction
A 2.0.0 final looks near given the candidate cadence, but this feed will not say what it contains.
SiYuan
5.0COLLAB
SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.
◆ Current state
SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.
◆ Where it's heading
The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.
◆ Prediction
A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
