What is Docspell?

Docspell's tagged releases stopped in 2025; the upload API only moves on the nightly.

No numbered release has landed since 0.43.0, which was itself a fixes-and-dependencies close-out. Work continues on the rolling nightly tag, where the current build adds optional priority to upload metadata, returns file keys and job ids from the upload API, and exposes a secured endpoint to fetch a file by key. That is real API surface, but it reaches only users willing to run nightly builds.

What is Outline?

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

Docspell vs Outline: editorial side-by-side

2.5

Docspell's tagged releases stopped in 2025; the upload API only moves on the nightly.

◆ Current state

No numbered release has landed since 0.43.0, which was itself a fixes-and-dependencies close-out. Work continues on the rolling nightly tag, where the current build adds optional priority to upload metadata, returns file keys and job ids from the upload API, and exposes a secured endpoint to fetch a file by key. That is real API surface, but it reaches only users willing to run nightly builds.

◆ Where it's heading

The project is drifting toward nightly-only distribution: contributors keep landing work, maintainers keep not cutting tags. The newest additions cluster on programmatic ingestion — a caller submitting a document, then retrieving it by key — which points at Docspell being shaped as a component other systems feed rather than a standalone archive.

◆ Prediction

The upload-API work in #3338 is the most likely core of a next tagged release if one is cut. Whether the tagged line resumes at all is not readable from these notes.

6.3

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

◆ Current state

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

◆ Where it's heading

Outline is positioning itself as an agent-native knowledge base rather than just a polished wiki. The pattern across the last several releases is deliberate: MCP support expanded significantly in April, Open Knowledge Format export added portability in September, and WebMCP makes the agent integration surface browser-accessible. The OKF export is also a meaningful portability move — structured markdown bundles that survive outside Outline reduce lock-in risk and could attract teams evaluating it against more closed alternatives.

◆ Prediction

Outline will likely expand the WebMCP tool surface — the April MCP work gave them a solid set of structured tools to expose, and WebMCP makes those available without setup friction. Expect more agent-facing capabilities (summarization, cross-document linking, task extraction) rather than another round of baseline UX polish.
