A side-by-side editorial comparison of Zulip and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
Zulip vs SiYuan: at a glance
What is Zulip?
Zulip donates itself to a nonprofit foundation as its founder joins Anthropic.
Two consequential moves landed inside three weeks. Tim Abbott, Zulip's longtime leader, is stepping back to join Anthropic along with three senior Kandra Labs engineers, and the for-profit company is being donated to a newly formed independent Zulip Foundation. In parallel, Zulip Server 12.0 shipped — roughly 5,500 commits, end-to-end encryption for mobile push notifications, a major Docker upgrade, and configurable image previews — alongside routine 11.x security patches and a self-hosted AI search integration via Atolio.
What is SiYuan?
SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

Zulip donates itself to a nonprofit foundation as its founder joins Anthropic.
◆ Current state
Two consequential moves landed inside three weeks. Tim Abbott, Zulip's longtime leader, is stepping back to join Anthropic along with three senior Kandra Labs engineers, and the for-profit company is being donated to a newly formed independent Zulip Foundation. In parallel, Zulip Server 12.0 shipped — roughly 5,500 commits, end-to-end encryption for mobile push notifications, a major Docker upgrade, and configurable image previews — alongside routine 11.x security patches and a self-hosted AI search integration via Atolio.
◆ Where it's heading
Governance is being separated from product velocity: the foundation owns long-term stewardship while the technical roadmap (E2E push, self-hostable AI integrations, hardened install path) keeps targeting security-conscious, self-hosted teams. Losing the founder to a frontier AI lab is the kind of transition that either accelerates community ownership or stalls momentum — the 12.0 commit volume suggests the team built up runway before the announcement.
◆ Prediction
Expect the Zulip Foundation to publish formal governance, a maintainer charter, and a funding model in the next quarter, and for the AI integration story (Atolio-style connectors rather than first-party AI) to harden into Zulip's positioning against Slack and Mattermost's first-party AI bets.

SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
◆ Current state
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.
◆ Where it's heading
The headline direction is extensibility and automation: a plugin-capable kernel, CLI access, and secrets/variables move SiYuan from a self-contained app toward something developers can script and integrate. The breaking kernel API changes and the new serve subcommand are the cost of that platform shift. Underneath, steady editor/database hardening and broad localization continue.
◆ Prediction
Expect 3.7.0 to ship from the beta line with the plugin system and CLI as its banner features, followed by an ecosystem period of plugins and integrations building on the new kernel APIs. The repeated dev-build entries don't add direction beyond this.
