Netpeak Software vs SiteAnalyzer (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 SiteAnalyzer if

• Fits if you're an SEO freelancer on Windows who'd rather pay once than subscribe
• Works for studying how internal links and PageRank flow through a site

Look elsewhere if

• Skip it if you work on a Mac or Linux, as it's Windows only and Wine or CrossOver are the vendor's workarounds
• Not for you if your site loads links with JavaScript, which it doesn't render yet
• Tight if you stay free, at 100 pages a crawl, 1 project and 1 thread
• Watch out: the home page table shows 500 pages and 5 threads for free, while the pricing page says 100 and 1
• Pricey if you work across several computers, as each $108 license covers one

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.

SiteAnalyzer

• It runs only on Windows; the vendor suggests Wine on Linux and CrossOver on a Mac as workarounds.
• It does not render JavaScript, so links loaded by scripts are missed; the FAQ says rendering is planned.
• The pricing page caps the free version at 100 pages and 1 thread, while the home page table shows 500 pages and 5 threads.
• Each Pro license covers one computer; refunds are offered within 30 days of purchase.
