What is Excalidraw?
Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.
This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.
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.

Excalidraw
0.0COLLAB
Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.
◆ Current state
This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.
◆ Where it's heading
The package's direction has been to expose more of the editor to host applications — API subscribers, programmatic element creation, viewport control, sidebar tabs — so Excalidraw can be embedded as a component rather than only used as a site. The ESM transition fits that: tree-shakable output matters to the teams shipping it inside their own products. With no releases captured in over a year, this source no longer says anything about current activity, which more likely reflects the crawl target than the project.
◆ Prediction
Insufficient data for a forward call from this feed: the last captured release predates the window by more than a year, so any prediction would be about the package's dormancy rather than Excalidraw's actual roadmap.
Outline
6.3COLLAB
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.
