Surfer scores and optimizes content you write 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.
Surfer SEO is a browser-based content optimization platform. It analyzes top-ranking pages and gives writers a real-time content editor with a SEO score, so the content they write better matches what is already ranking. The work happens in Surfer’s app, not in your codebase.

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.
Surfer works in its own browser app. You write or paste content into the editor, optimize against its score, then export and publish it to your site yourself.
If your site lives in a codebase, SEOAgent keeps SEO where your work already is. If you write in a browser and want live scoring, Surfer 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.
Surfer gives guidelines from SERP analysis and a target content score. Acting on them — and judging what actually matters — is left to you and your writers.
SEOAgent leans on your own performance data and keeps a human in the loop on every change. Surfer gives strong optimization signals but no measurement-driven workflow.
Built for founders and dev/SaaS teams who ship their site from a repo and already use a coding agent. Local-first, developer-credible, no AI slop.
Built for writers, content teams, and agencies who produce articles in a browser and want them optimized to rank.
Pick SEOAgent if a developer or coding agent touches the site. Pick Surfer if a writing team owns the content.
SEOAgent’s Skill is free forever and runs locally; the $49 per-site cloud tier adds Search Console measurement, research, and review. Surfer is a subscription tool with no free working tier. Verify Surfer’s current plan pricing on their site before quoting it.
They solve adjacent problems differently. Surfer optimizes content you write 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.
Yes. Some teams draft and score long-form articles in Surfer, then use SEOAgent to ship and continuously improve them in the codebase with real performance data. There is overlap on research, so most teams settle on one as their primary tool.
No real-time browser editor. SEOAgent’s model is different: your coding agent writes and edits pages in the repo, and the cloud layer reviews them against your Search Console performance and competitor research, proposing changes you approve.
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.
