MarketMuse analyzes content gaps and plans strategy in a browser. SEOAgent gives your coding agent the tools to build and improve SEO pages in your codebase — measured against real Search Console data, approved by you.
Install the Skill — freeSEOAgent is the SEO engine for coding agents. It ships as a free Skill for Claude Code, Cursor, and Codex (plus a local CLI) that audits your site and builds landing pages and blog articles directly in your repo. The optional cloud layer analyzes Google Search Console performance, researches competitors and keywords, and proposes evidence-backed updates — which your coding agent implements only after you approve them.
MarketMuse is a browser-based content intelligence platform. It uses topic modeling to surface content gaps, score drafts, and plan content strategy, then hands those briefs and recommendations to your writing team. The planning happens in MarketMuse’s app; producing and publishing the content is on you.

SEOAgent works inside your codebase through your coding agent. Pages, metadata, schema, and internal links are created and edited as real files in your repo — and ship through your existing CI/CD.
MarketMuse works in its own browser app. It produces gap analysis, briefs, and recommendations there; turning those into published pages is left to your writers and developers.
If your site lives in a codebase, SEOAgent keeps SEO where your work already is. If you want deep planning and topic modeling in a browser, MarketMuse fits that flow.
The cloud layer grounds suggestions in your real Google Search Console data and competitor research, then proposes specific, evidence-backed updates. Nothing changes until you approve it.
MarketMuse models topics and scores opportunities to guide strategy, but it does not ship the work. Acting on its recommendations — and producing the pages — is up to your team.
SEOAgent ties suggestions to your own performance data and then builds the change in your repo. MarketMuse gives strong strategic intelligence but stops at the plan.
Built for founders and dev/SaaS teams who ship their site from a repo and already use a coding agent. Local-first, developer-credible, grounded in your real expertise rather than AI slop.
Built for content teams and agencies who need deep strategic planning and topic intelligence to direct professional writers.
Pick SEOAgent if a developer or coding agent touches the site. Pick MarketMuse if a content team needs heavy strategic planning before writing.
SEOAgent’s Skill is free forever and runs locally; the $49 per-site cloud tier adds Search Console measurement, research, and review that ships changes into your repo. MarketMuse offers a limited free tier and paid plans for deeper intelligence — verify its current plan pricing on marketmuse.com before quoting it.
They solve adjacent problems differently. MarketMuse plans content and models topics in a browser; SEOAgent gives your coding agent the tools to build and improve SEO pages in your codebase, grounded in Search Console data. If your site lives in a repo, SEOAgent is the more natural fit.
No. MarketMuse is a planning and intelligence platform — it produces gap analysis, briefs, and scores, but your team still writes and publishes the content. SEOAgent grounds suggestions in your Search Console data and has your coding agent build the changes in the repo, which you approve.
Yes. Some teams plan strategy and find gaps in MarketMuse, then use SEOAgent to build and continuously improve the pages in the codebase with real performance data. There is overlap on research, so most teams settle on one as their primary tool.
The Skill is free forever and runs locally. Pro is $49 per site per month and adds Google Search Console analysis, competitor and SERP research, and cloud review of suggested updates that sync back to your repo with one command.
Install the free SEOAgent Skill for Claude Code, Cursor, or Codex and run your first audit in minutes. Add the cloud when you want measurement and review.
