Picked by use case, not by marketing budget.
Moz Pro's strength is Domain Authority and a polished marketing-team UI. If you don't need DA and you want SEO checks programmatically, the right alternative depends on what you actually want.
If you spend most of your Moz Pro time on site audits and you'd rather get JSON your code can act on, SEO Score API is the cheapest, fastest path. If you rely on Moz Pro for backlinks, keyword research, or rank tracking, no API-first tool will fully replace it. For a direct feature-by-feature breakdown, see SEO Score API vs Moz Pro.
Run an audit before you commit to anything.
