Whimsical vs HumHub: at a glance
What is Whimsical?
Whimsical rebuilt itself as a diagramming surface agents can drive, then went back to polishing the canvas
The agent work landed in two steps: April put Whimsical inside ChatGPT and shipped a remote MCP server reachable from Claude, Cursor and other agents without the desktop app; July shipped Ask Whimsical, an in-product AI agent that creates diagrams, wireframes and mind maps and searches the workspace. Since then the releases have gone back to craft — dark mode across whiteboarding and embeds, Turbopuffer-backed search, icons inside flowchart shapes, snappier elbow connectors, SVG export and a Linux desktop app. MCP coverage keeps widening, most recently to editable doc tables.
What is HumHub?
HumHub's public feed carries only betas, and 1.19's is mostly about surviving the upgrade.
The three releases visible here are all pre-release: 1.19.0-beta.1 in July, and 1.18.0-beta.6 and beta.5 before it. The 1.19 beta is dominated by upgrade-path and data-integrity repair — a foreign key violation that aborted the 1.19 comment content_id migration on databases with orphaned rows, a fatal error when deleting a user or running PurgeDeletedContents against content whose underlying record was gone, and a permissions fix where users with ManageSettings but not ManageModules were offered a Configure button on disabled modules. The 1.18 betas are ordinary polish: login screen layout, theme inheritance, validators, translations and installer fixes.

◆ Current state
The agent work landed in two steps: April put Whimsical inside ChatGPT and shipped a remote MCP server reachable from Claude, Cursor and other agents without the desktop app; July shipped Ask Whimsical, an in-product AI agent that creates diagrams, wireframes and mind maps and searches the workspace. Since then the releases have gone back to craft — dark mode across whiteboarding and embeds, Turbopuffer-backed search, icons inside flowchart shapes, snappier elbow connectors, SVG export and a Linux desktop app. MCP coverage keeps widening, most recently to editable doc tables.
◆ Where it's heading
Whimsical is treating the agent as a second class of user with the same rights as a person: everything reachable in the UI is progressively becoming reachable over MCP, and the doc tables becoming editable rather than readable is the tell. Meanwhile the human-facing work targets the reasons people leave a diagramming tool — search that finds things across a large workspace, exports that survive the trip elsewhere, and a canvas that is comfortable to sit in for hours. The two tracks are not competing for the same roadmap slots, which suggests both are considered core.
◆ Prediction
Expect MCP write coverage to keep expanding toward boards and wireframes, matching what Ask Whimsical can already do in-product, and for the ChatGPT integration to be joined by equivalents in other assistant surfaces given the remote MCP server already makes that cheap.
HumHub
2.5COLLAB
HumHub's public feed carries only betas, and 1.19's is mostly about surviving the upgrade.
◆ Current state
The three releases visible here are all pre-release: 1.19.0-beta.1 in July, and 1.18.0-beta.6 and beta.5 before it. The 1.19 beta is dominated by upgrade-path and data-integrity repair — a foreign key violation that aborted the 1.19 comment content_id migration on databases with orphaned rows, a fatal error when deleting a user or running PurgeDeletedContents against content whose underlying record was gone, and a permissions fix where users with ManageSettings but not ManageModules were offered a Configure button on disabled modules. The 1.18 betas are ordinary polish: login screen layout, theme inheritance, validators, translations and installer fixes.
◆ Where it's heading
The 1.19 cycle is being spent making the migration survivable on real installations rather than adding capability, which is the usual shape when a schema change meets databases that have accumulated orphaned rows over years. The permission fix points the same way: tightening the boundary between managing settings and managing modules is cleanup of an authorisation model, not an extension of it.
◆ Prediction
Only beta tags appear in this feed, so a 1.19.0 stable is the obvious next milestone, but nothing here dates it. Note that the gap between the 1.18 betas and the 1.19 beta is roughly six months, which is the only cadence signal available.
