Head to head

One Model vs Workday

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

One Model

Sales-quoted

Enterprise people-analytics platform that unifies HR data and adds AI Q&A plus an MCP server. Pricing is quote-based.

Where One Model fits

Enterprise people-analytics teams on Workday or SAP
CHROs who need board-ready workforce stories
Teams that want AI chat on governed HR data
Companies replacing spreadsheet HR metrics

Workday

Sales-quoted

Enterprise HCM of record where recruiting is one module. Quote only, with long implementations and a tenant-scoped MCP rather than a public one.

Where Workday fits

Global enterprises already on Workday
HR IT teams standardising the HCM
Talent teams that must live in the system of record
Selections that name Workday Recruiting

Where they pull apart

One Model

Stands out: MCP lets Claude, Copilot, and ChatGPT query governed workforce data instead of a generic model.

Watch out: Editions are named but unpublished. One AI predictive modeling is Enterprise-only. MCP is an add-on on lower editions.

Not the right fit for

Small HR teams that want self-serve pricing
Buyers who only need a simple pulse survey

Workday

Stands out: It is the system of record for very large companies; recruiting rides along with it.

Watch out: Recruiter sentiment is among the most negative of any platform here, and implementations run long.

Not the right fit for

Small businesses
Agencies
Teams that want a public MCP endpoint
