SiYuan vs AFFiNE: at a glance
What is SiYuan?
SiYuan keeps grinding on its database engine, flashcards, and cross-platform reach
SiYuan is a local-first, block-based knowledge base — self-hostable, privacy-oriented, and increasingly a Notion-style database tool as much as an editor. The current cycle pours effort into the database layer (relations, rollups, deep links, column alignment, templates), spaced-repetition flashcards (now buildable from callouts and blockquotes), and broad platform parity across iOS, Android, HarmonyOS, and tablets.
What is AFFiNE?
A canary-speed engineering grind on storage GC and import reliability
AFFiNE is iterating through daily canary and beta builds, and the current focus is backend housekeeping: implementing and hardening document and blob garbage collection so trashed and orphaned workspace docs reconcile correctly, plus reliability fixes for Obsidian import, kanban row handling, and desktop window behavior. The feed carries near-duplicate canary/beta entries for the same PRs, so the real change count is lower than the release count suggests.

◆ Current state
SiYuan is a local-first, block-based knowledge base — self-hostable, privacy-oriented, and increasingly a Notion-style database tool as much as an editor. The current cycle pours effort into the database layer (relations, rollups, deep links, column alignment, templates), spaced-repetition flashcards (now buildable from callouts and blockquotes), and broad platform parity across iOS, Android, HarmonyOS, and tablets.
◆ Where it's heading
The product ships on a fast alpha/beta/stable train, with each stable (v3.7.2, v3.7.3) consolidating dozens of small enhancements plus routine security fixes. Direction is steady rather than pivoting: deepen the database toward Notion parity, harden mobile/HarmonyOS input, and expand flashcards — with AI touched only lightly (provider/model config tweaks, an AI edit window).
◆ Prediction
Expect a v3.7.4 stable that folds in the current alpha's automatic heading numbering, expanded flashcard sources, and precise database relation filters. Continued HarmonyOS and mobile-input polish is the safe bet; no larger architectural or AI shift is visible in these entries.

A canary-speed engineering grind on storage GC and import reliability
◆ Current state
AFFiNE is iterating through daily canary and beta builds, and the current focus is backend housekeeping: implementing and hardening document and blob garbage collection so trashed and orphaned workspace docs reconcile correctly, plus reliability fixes for Obsidian import, kanban row handling, and desktop window behavior. The feed carries near-duplicate canary/beta entries for the same PRs, so the real change count is lower than the release count suggests.
◆ Where it's heading
The work is maturation, not expansion — AFFiNE is paying down correctness debt in its sync and storage layer (GC resumability, checkpoint persistence, blob discovery) that matters most for self-hosted and larger workspaces. Import fidelity from Obsidian signals continued attention to migration as an acquisition path.
◆ Prediction
Expect the doc/blob GC work to converge into a stable 0.27.3 release, with the canary stream moving on to the next reliability target once reconciliation lands cleanly.
