FlexQueries vs Semrush
Both sit in SEO & marketing. Here is how they differ on the things you can actually check.
FlexQueries
flexqueries.com
Keyword, SERP, backlink, competitor, rank-tracking and site-audit research, plus keyword research for the App Store and Amazon and checks of how often AI answers mention and cite a brand. It works in the browser, through a REST API and through an MCP connection for Claude, Cursor and ChatGPT, and Google Search Console data does not reduce the balance. There is no subscription, monthly minimum or per-seat fee: an account adds credits, each action is charged from that balance with an estimate shown before it runs, and unused credits do not expire.
Semrush
semrush.com
SEO, paid search, content, social and PR tooling in one suite — enormous surface area, priced accordingly.
