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

Pick Netpeak Software if

• Fits if you'd rather own a desktop crawler than rent a web suite, with lifetime licences from $496
• Works for checking hundreds of domains against Ahrefs or Moz metrics at once

Look elsewhere if

• Skip it if you need rank tracking or keyword research, which none of the apps does
• Not for you if you're on a Mac and need Checker, as it runs on Windows only
• Tight if you want several apps, since each is bought separately and bundles are yearly only
• Watch out: Limonity Backlinks only watches links you add; it doesn't find new backlinks
• Pricey if you want Limonity On-Page, at $99 a month per user, and there's no web or phone version

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

Netpeak Software

• These are desktop apps for Windows and macOS with no web version, and Netpeak Checker runs on Windows only.
• Each app is bought separately; bundles of two or three apps are sold yearly only.
• Limonity Backlinks monitors links you add yourself; it does not discover new backlinks to your site.
• There is no rank tracking or keyword research; the apps cover crawling, bulk URL checks and monitoring.

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.
