HedgeDoc vs SiYuan: at a glance
What is HedgeDoc?
A collaborative markdown editor on a security-driven maintenance cadence.
HedgeDoc's 1.x line ships every one to two months and is dominated by security response. Recent releases carry seven advisories between them — HTML injection via an email localpart, YAML frontmatter denial of service, CSRF in the Gist export, a rate-limit bypass through CF-Connecting-IP, a permission-value validation gap, missing upload security headers, and script execution in uploaded SVGs. Around those sit configuration knobs for the external-link warning, webp uploads, and rate limits.
What is SiYuan?
SiYuan's 3.8.9 betas add only LaTeX paste fixes as the release nears stable.
SiYuan has published four 3.8.9 betas since October 26. Beta.2 and beta.3 carry the same notes as beta.1; beta.4 adds only better LaTeX math delimiter handling when pasting and importing. The cumulative list is long: resizable table rows, database-field backlink filters, mind map themes and node copy/paste, block-reference collection through database automation, macOS proxy detection, TIFF previews and better sync checkout.

HedgeDoc
2.5COLLAB
A collaborative markdown editor on a security-driven maintenance cadence.
◆ Current state
HedgeDoc's 1.x line ships every one to two months and is dominated by security response. Recent releases carry seven advisories between them — HTML injection via an email localpart, YAML frontmatter denial of service, CSRF in the Gist export, a rate-limit bypass through CF-Connecting-IP, a permission-value validation gap, missing upload security headers, and script execution in uploaded SVGs. Around those sit configuration knobs for the external-link warning, webp uploads, and rate limits.
◆ Where it's heading
Two threads run in parallel. The perimeter work reduces attack surface and maintenance burden at once: old API endpoints and unused config are deleted, Node 18 support is dropped now that its security window has closed, and features added in one release tend to gain an off switch in the next. The second thread is realtime correctness — concurrent-editing data loss, connections dropped mid-handshake, operations discarded during revision gap recovery — which is the only work aimed at the core editing experience rather than its edges.
◆ Prediction
Expect the 1.x line to continue as security and correctness maintenance, with more legacy endpoints and configuration removed rather than new editing features added.
SiYuan
5.0COLLAB
SiYuan's 3.8.9 betas add only LaTeX paste fixes as the release nears stable.
◆ Current state
SiYuan has published four 3.8.9 betas since October 26. Beta.2 and beta.3 carry the same notes as beta.1; beta.4 adds only better LaTeX math delimiter handling when pasting and importing. The cumulative list is long: resizable table rows, database-field backlink filters, mind map themes and node copy/paste, block-reference collection through database automation, macOS proxy detection, TIFF previews and better sync checkout.
◆ Where it's heading
3.8.9 is a large, mostly incremental release, with mind maps and database automation as the two deepest threads, and pinned agent sessions showing a growing AI layer. Four betas in two days with a nearly frozen feature list mean the release is in final fix mode.
◆ Prediction
Expect a stable 3.8.9 within days, consistent with past cycles.
