SiYuan vs Happeo: at a glance
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.
What is Happeo?
Happeo's feed is intranet and knowledge-management SEO content, not a product changelog.
Happeo's crawled feed is its marketing blog — knowledge-management explainers, intranet-category arguments (why Notion isn't an intranet), competitor comparisons (vs. LumApps), enterprise-AI-search think-pieces, and a Visma customer case study. No entries describe shipped features.

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.

5.0COLLAB
Happeo's feed is intranet and knowledge-management SEO content, not a product changelog.
◆ Current state
Happeo's crawled feed is its marketing blog — knowledge-management explainers, intranet-category arguments (why Notion isn't an intranet), competitor comparisons (vs. LumApps), enterprise-AI-search think-pieces, and a Visma customer case study. No entries describe shipped features.
◆ Where it's heading
The narrative centers on enterprise AI search and knowledge management as the intranet's core job, with Happeo positioning against general tools (Notion) and direct rivals (LumApps). It is a content cadence, not a release log; product direction isn't visible here.
◆ Prediction
Expect continued AI-search and knowledge-management positioning content; feature-level signal requires Happeo's actual release notes.
