There are now two ways to get a free, AI-powered SEO audit without paying an agency $5–10K/month. Both run on your own machine, and both use Claude or another AI coding tool as the engine. But they're built for different people.

This isn't a "we're the best at everything" post. We built the SEO Audit Report Builder, but we'll tell you straight up when Claude SEO is the better pick.

The one-sentence version

Claude SEO creates audits fast, for developers who live in the terminal. The SEO Audit Report Builder delivers a structured, client-ready report for B2B SaaS founders and marketing teams. The choice comes down to whether you prioritise velocity or systematic methodology.

Where Claude SEO wins

	Claude SEO	SEO Audit Report Builder	Why they win
Speed to first audit	30 seconds	5–10 minutes	Install automation vs. manual setup.
Breadth	25 sub-skills: local, e-commerce, backlinks, hreflang, image SEO	6 skills: on-page, technical, content, SaaS strategy	Broader coverage vs. specialised depth. Need a backlink or hreflang audit? They have it.
Social proof	7,000+ GitHub stars, 31K+ YouTube views, testimonials	A public methodology + a worked example	Community adoption vs. transparency. Trust is earned before the first visit — they have it.
Extensions	DataForSEO, Ahrefs, Semrush, Firecrawl MCP	Self-contained	If you already pay for Ahrefs or Semrush, their MCP integration is genuinely useful.
Auto-detection	Detects SaaS vs. local vs. e-commerce vs. publisher	Asks the human at kickoff	Less cognitive load — the tool figures out what kind of site you have.
Community velocity	Contributors shipping new skills each release	Solo project	They get better faster because other people build on it.

Bottom line: if you're a developer who saw the demo and wants to audit a site right now, install Claude SEO. It's the right tool for that job.

Where we win

	Claude SEO	SEO Audit Report Builder	Why we win
No terminal required	`git clone && bash install.sh`	Download a GUI app (Cursor), download a file, open it	A SaaS founder or marketer who's never opened a terminal literally can't use Claude SEO. They can use this.
Scoring approach	0–100 score, auto-calculated from crawl + PSI — instant	0–100 score across 7 SaaS-weighted categories: 3 read straight off the tools, 4 graded on fixed rubric bands	Both give a trackable number. Ours is hybrid by design — ~40% read directly off the crawler, PageSpeed and schema validation, so an unchanged site re-scores within a point or two, with a per-category breakdown that shows where to fix things.
SaaS depth	Generalist: one framework for an electrician and a SaaS	Purpose-built for B2B SaaS: funnel mapping, pSEO playbooks, thin-site guard	Their auto-detection tailors the surface, not the methodology depth.
Report quality	Health score + action plan — for the person who ran it	Score + per-category breakdown + executive & leadership summaries + 90-day plan with effort estimates and impact ratings + deprioritised list + revenue opportunities	If you're delivering to a client or team, our report is built to be handed over — not just read.
Worked example	YouTube demo	A real, anonymised two-site audit — scores, Core Web Vitals before/after, 90-day plan	Static and linkable: you can read the actual output in 60 seconds, no install.
Install trust	`bash install.sh` runs arbitrary code	Download a markdown file — nothing executes	For the privacy-conscious, running a shell script from the internet is a non-starter.
Tool-agnostic & no lock-in	Claude Code only; skills live in proprietary settings	Claude Code, Cursor, or Codex — two plain markdown files	You're not locked to one ecosystem, and the methodology is still readable if you stop using the runbook. An optional skill pack adds a `/seo-audit` tab-complete command.

Who should use Claude SEO

You live in the terminal and git clone && bash install.sh feels natural
You want the single fastest path from decision to a score — 30 seconds
You need breadth: local SEO, e-commerce, backlinks, hreflang, image SEO
You're a solo developer auditing your own projects
You already pay for Ahrefs or Semrush and want MCP integration

Who should use the SEO Audit Report Builder

You're a B2B SaaS founder or marketing team that doesn't live in the terminal
You want a score and the per-category context that tells you where to fix things
You need a report you can hand to a client or team — with effort estimates, impact ratings, and a 90-day plan
You're privacy-conscious and don't want to run arbitrary install scripts
You use Cursor (or might) and want tooling that isn't locked to Claude Code
You value methodology depth: confidence calibration, data-maturity gating, thin-site guardrails

The honest truth

Claude SEO is a better product. Faster, broader, and with real momentum: thousands of stars, a popular demo video, and a growing community. For a developer who wants to audit a site right now, it's the obvious choice.

We're a better methodology. Our audit asks deeper questions for a narrower audience, and the report is built to be delivered. We have a 0–100 health score too, across 7 SaaS-weighted categories, ~40% read straight off the tools (so it's reproducible) and the rest graded against published rubric bands, plus an optional skill pack and a full worked example you can read end to end.

The risk on our side is real: "better methodology" is a feature, not a product. Claude SEO shipped a polished product. If speed and breadth matter more to you than depth and deliverability, use Claude SEO. It works. But if you want to know why each fix matters, not just that it does, that's why we built this.
