Lumar vs Screaming Frog SEO Spider (2026): which should you pick?

Pick Lumar if

• Fits if your site has hundreds of thousands of pages and an enterprise budget
• Makes sense if you want SEO checks to block a release in your CI/CD pipeline

Look elsewhere if

• Not for you if you want to see a price before talking to sales, as it's quote-only
• Skip it if you want to try it first, since there's no free plan or trial on record
• Tight if you crawl a lot, as active projects and URLs per billing period are capped by contract
• Watch out: SEO and GEO professional services are a separate monthly contract

Pick Screaming Frog SEO Spider if

• Fits if you're a technical SEO who audits large sites from your own computer
• Works for sites under 500 URLs, which the free version crawls with no time limit

Look elsewhere if

• Skip it if you want keyword research, rank tracking or backlinks, as it only crawls
• Not for you if you'd rather not learn technical SEO terms, XPath or regex
• Tight if your computer is short on memory or storage, since crawl size depends on it, and there's no web or phone version
• Pricey if a team needs it: licences are $279 per user a year, so two people need two
• Watch out: the free version can't save crawls, render JavaScript, schedule audits or connect to Google data

Lumar

• No prices are published: the pricing page is a quote form, and packages are built from the apps and metrics a team picks.
• Accounts have limits on active projects and on URLs crawled per billing period, set in each contract.

• SEO and GEO professional services are sold as a separate monthly contract.

Screaming Frog SEO Spider

• Licences are per user and last one year; two people need two licences.
• It is a desktop app, so crawl size depends on the computer's memory and storage.
• The free version cannot save crawls, render JavaScript, schedule audits or connect to Google data.
