Excalidraw vs Mattermost
A side-by-side editorial comparison of Excalidraw and Mattermost — release velocity, themes, recent moves, and the top alternatives to consider.
Excalidraw vs Mattermost: at a glance
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 Mattermost?
Mattermost v12 puts user-scoped permissions, private models and audit trails on every agent action.
Mattermost's feed spent five weeks on security and resilience essays; the last product release was v11.11's data-spillage exposure report. v12 changes that: agents now act with the requesting user's access rather than a shared service account, can run on private models, and leave an audit trail per action. The announcement is short on detail, but the pitch is clear and aimed at defense and regulated buyers.

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.
Mattermost
6.3COLLAB
Mattermost v12 puts user-scoped permissions, private models and audit trails on every agent action.
◆ Current state
Mattermost's feed spent five weeks on security and resilience essays; the last product release was v11.11's data-spillage exposure report. v12 changes that: agents now act with the requesting user's access rather than a shared service account, can run on private models, and leave an audit trail per action. The announcement is short on detail, but the pitch is clear and aimed at defense and regulated buyers.
◆ Where it's heading
The essays on zero trust, data spillage and out-of-band response were building toward this. Mattermost is positioning its AI agents as governed, mission-safe tools inside its classified-environment niche rather than competing on agent breadth. The in-house Matty Code agent shows it also uses agents to build the product itself.
◆ Prediction
Expect v12.x follow-ups that publish admin controls and audit-log detail for agent actions, plus more deployment-focused content aimed at defense buyers.
