AuditLamp vs Screaming Frog.
Screaming Frog's SEO Spider is the technical SEO's workbench: a desktop crawler you configure, point and read yourself. AuditLamp is a hosted audit that fetches your site and hands back graded verdicts in plain language. One gives you the data; the other gives you the answer. Which one you need depends on who is asking.
Crawl control, for people who read crawls.
Nothing hosted matches a local crawler you fully control. Custom extraction rules, JavaScript rendering comparisons, crawl-vs-render diffs, massive site crawls, raw exports into your own spreadsheets and scripts: for a technical SEO or developer, Screaming Frog is the standard workbench and has earned that place over many years. If you know exactly what you are looking for in crawl data, it is the right tool and we say so without hedging.
Verdicts, not tables.
The output is a diagnosis, not a dataset. A crawl export tells you a title is 34 characters; it does not tell you whether that matters. AuditLamp grades every finding against documented requirements, ranks the damage worst first, and writes it in the language of the person who pays for the website.
The AI half of visibility is graded, not just crawled. Access probes by named AI agent (core.ai_bot_matrix), edge-block detection that catches a CDN silently 403ing GPTBot while robots.txt says allow (gate.bot_reachability), citability of your paragraphs (amp.citable_facts, core.answer_block), llms.txt and training-versus-retrieval policy (core.llms_txt, core.train_vs_retrieve).
Nothing to install, nothing to configure. Paste a URL, get the whole site up to 150 pages graded free, no email. Security, accessibility and privacy grades ride along in the 48-check Vibe Audit. Weekly monitoring and before/after proof are a flat $29 a month, not a skill you have to schedule.
Trend and proof are built in. A desktop crawl is a snapshot on your machine. Monitor keeps score history, rescans every Monday, emails you when something drops, and keeps the receipts.
The pro keeps the workbench. The owner needs the verdict.
If you are a technical SEO, keep Screaming Frog; you might still run AuditLamp for the AI-visibility grading and the client-readable report you do not have to write yourself. If you are a business owner, you do not need a crawler and a course to read it; you need to know what is broken, in order, this week. That is the free scan.
