Browser Research Tool vs SEO Engine for Coding Agents
SEOAgent
SEOAgent 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.
Frase
Frase is a browser-based content research and optimization tool. It analyzes top-ranking pages, builds content briefs, and scores drafts against a target so writers can match what already ranks. The work happens in Frase’s app, and you export and publish the result yourself.

Key Differences
Where the work happens
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.
Frase works in its own browser app. You research, brief, and write against its score in the editor, then export and publish the content 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 against the SERP, Frase fits that flow.
How decisions get made
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.
Frase analyzes the SERP and gives you a target content score and brief. Judging what to act on — and shipping it — is left to you and your writers.
SEOAgent leans on your own performance data and keeps a human in the loop on every change. Frase gives strong research and scoring signals but no in-repo, measurement-driven workflow.
Who it’s built for
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 writers, content marketers, and agencies who research and optimize articles in a browser before publishing.
Pick SEOAgent if a developer or coding agent touches the site. Pick Frase if a writing team owns the content.

Frequently Asked Questions
Is SEOAgent a Frase alternative?

Can I use SEOAgent and Frase together?
Yes. Some teams research and draft long-form articles in Frase, 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.
How much does SEOAgent cost?
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.
