Sellfy vs Wheelhouse

Wheelhouse ships API surface faster than app features. The current release rolls segment performance metrics up across every listing a saved segment matches, works across owned and shared or managed listings, and converts monetary metrics into whichever currency the caller asks for. It reaches the same MCP server that already exposes the platform to AI assistants, so the aggregate is available from a prompt as well as an endpoint.

The sequencing is deliberate: expose everything through an API, make it reachable from AI clients, then let it push events out so partners can build without polling. This release is the follow-through on a promise made in July — the aggregated metrics endpoint was announced then, and now covers shared and managed inventory and multi-currency portfolios, which is what property managers running someone else's listings actually need. IntelliHost remains the proof of the model, a third party closing the full pricing loop on Wheelhouse rails.

With webhooks, scoreboards and segment aggregates in place, the remaining gap is write-side automation at portfolio scale rather than per-listing. Expect the partner roster to grow before the app does — the entries consistently describe the API as the product's leading edge.
