Paperless-ngx vs SiYuan: at a glance
What is Paperless-ngx?
Paperless-ngx is rebuilding for v3 with AI, a plugin framework, and a Tantivy search rewrite.
Two release lines run in parallel. The v2.20.x stable branch is in aggressive security-patch mode — five GHSA-tagged security releases in roughly two months (v2.20.7, 2.20.8, 2.20.9, 2.20.12, 2.20.15) plus a stream of permission-scope and workflow bug fixes. Meanwhile, v3.0.0-beta.rc1 just dropped with the largest feature surface in the project's history: Paperless AI, Remote OCR via Azure AI, sharelink bundles, document file versions, a document parser plugin framework, and a swap of the Whoosh search backend for Tantivy. The v3 cut also lands eleven explicit breaking changes — old API versions removed, encryption support dropped, Python 3.10 support cut, OCR control decoupled from archive-file control.
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.

5.0COLLAB
Paperless-ngx is rebuilding for v3 with AI, a plugin framework, and a Tantivy search rewrite.
◆ Current state
Two release lines run in parallel. The v2.20.x stable branch is in aggressive security-patch mode — five GHSA-tagged security releases in roughly two months (v2.20.7, 2.20.8, 2.20.9, 2.20.12, 2.20.15) plus a stream of permission-scope and workflow bug fixes. Meanwhile, v3.0.0-beta.rc1 just dropped with the largest feature surface in the project's history: Paperless AI, Remote OCR via Azure AI, sharelink bundles, document file versions, a document parser plugin framework, and a swap of the Whoosh search backend for Tantivy. The v3 cut also lands eleven explicit breaking changes — old API versions removed, encryption support dropped, Python 3.10 support cut, OCR control decoupled from archive-file control.
◆ Where it's heading
The arc is a generational rewrite landing on top of a hardened v2 foundation. The team is using v2.20.x to absorb security disclosures (often credited to community researchers) while v3 takes on the architectural debt — fresh migrations from scratch, removed legacy paths, a search engine swap, and a plugin framework that opens the parser surface to extensions. The simultaneous Paperless AI and Azure AI Remote OCR features signal a deliberate move into AI-augmented document processing rather than a passive integration.
◆ Prediction
Expect more v2.20.x security and bugfix releases through the v3 beta period, then a coordinated migration push when v3 stabilizes — Tantivy reindexing and the API-version removals will both gate that upgrade. Watch the next v3 beta for what Paperless AI actually exposes (suggestion-only vs auto-classification) and whether the plugin framework gets a public extension point doc.

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.
