AFFiNE vs SiYuan
A side-by-side editorial comparison of AFFiNE and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs SiYuan: at a glance
What is AFFiNE?
AFFiNE's canary stream is mostly dependency hygiene, with AI-model work just behind it
AFFiNE is a local-first, open-source knowledge base shipping near-daily canary builds. The recent window is dominated by automated maintenance: Renovate dependency bumps, CI action upgrades, a build-system migration to rspack, and small bug and reliability fixes. The more directional work, integrating Gemini 3.5 Flash and updating Claude Sonnet with a BYOK key UI, sits just outside this six-entry window.
What is SiYuan?
SiYuan opens up: a kernel plugin system and CLI turn the notes app into a platform
SiYuan is shipping at a high cadence on the 0.x line, and the headline of the current cycle is extensibility — a kernel plugin system, a new command-line interface, and in-place editing for embed blocks. Alongside it sit steady i18n and export-quality improvements.

AFFiNE's canary stream is mostly dependency hygiene, with AI-model work just behind it
◆ Current state
AFFiNE is a local-first, open-source knowledge base shipping near-daily canary builds. The recent window is dominated by automated maintenance: Renovate dependency bumps, CI action upgrades, a build-system migration to rspack, and small bug and reliability fixes. The more directional work, integrating Gemini 3.5 Flash and updating Claude Sonnet with a BYOK key UI, sits just outside this six-entry window.
◆ Where it's heading
Day-to-day cadence is maintenance churn that keeps the canary channel healthy rather than changing the product surface. The signal worth tracking is the embedded-AI investment from late May: model bumps plus bring-your-own-key provider UI point at AFFiNE positioning AI as a first-class part of the editing experience, not a bolt-on.
◆ Prediction
Expect continued rapid canary releases and more AI provider and model expansion building on the BYOK work. The dependency and CI churn will keep flowing in the background and isn't itself a signal of direction.

SiYuan opens up: a kernel plugin system and CLI turn the notes app into a platform
◆ Current state
SiYuan is shipping at a high cadence on the 0.x line, and the headline of the current cycle is extensibility — a kernel plugin system, a new command-line interface, and in-place editing for embed blocks. Alongside it sit steady i18n and export-quality improvements.
◆ Where it's heading
The product is moving from a self-contained privacy-first notebook toward an extensible platform: plugins at the kernel level, a CLI for automation, HTTPS/HTTP2 hosting, and broad language support. That widens both the developer surface and the self-host audience.
◆ Prediction
Expect a plugin ecosystem to form around the kernel plugin API, with SiYuan leaning further into self-hosted, automation-friendly workflows.
