Netpeak Spider
Netpeak Spider is desktop software from Ukraine-based Netpeak Software that crawls a website you point it at, checking 100+ technical SEO issues like broken links, redirects, and duplicate titles — using a built-in Chromium engine to render JavaScript pages first. It stores results locally on your machine, with no cloud version and no independent web index behind it.
The basic crawl-and-report loop is a weekend build; matching Netpeak Spider's 100+ tuned issue checks and memory-efficient crawling at scale is not.
What you lose building it yourself
- ✕Crawling large sites without your script running out of memory or threads
- ✕100+ pre-built issue checks with severity prioritization
- ✕Built-in Search Console, Analytics, and Sheets integrations
Why people still pay
Netpeak Spider's own free tier already proves a basic crawl is easy — what the subscription buys is not having to keep a scraper working yourself: safe crawling of much larger sites without running out of memory, a tuned library of 100+ issue checks, and maintained connectors to Search Console, Analytics, and Sheets.
BUILD YOUR OWN · WEEKEND SCOPE (SINGLE-SITE AUDIT)
A basic version is realistic for an AI coding tool to build in a day or two: crawl a site with an automated browser, follow internal links, and flag broken pages, missing titles, or long redirect chains, exporting results to a spreadsheet. What takes real, ongoing engineering instead of a weekend is Netpeak Spider's 100+ tuned issue checks, memory-efficient crawling of very large sites, and maintained Search Console/Analytics connectors.
StackA headless browser library (Puppeteer/Playwright-style) for crawling and JS rendering · a URL queue with politeness/rate limiting · an HTML parser for links, titles, and meta tags · a CSV export · your own hosting or local run.
Build a command-line crawler in Python. Given a start URL, follow only same-domain internal links up to 500 pages. Use Playwright to render JavaScript before reading each page's final HTML. Record per page: status code, title, meta description, and outbound links, to a CSV. Flag broken links, missing/duplicate titles, and redirect chains over 2 hops. Respect robots.txt, with a 1s delay between requests.

QUESTIONS
Is there a free version?
Yes — free up to 500 URLs per crawl with 5 threads. The paid Pro tier ($20/month, $193/year, or a $496 one-time lifetime option) removes the URL cap and raises thread count to 200.
Does it use AI to crawl or analyze pages?
No sign of it — Netpeak's own product pages describe a rule-based crawl and issue-detection engine, with no AI-assisted extraction feature or AI-assistant connector mentioned as of August 2026.
Does it run in the cloud, or only as desktop software?
Desktop only, for Windows and macOS. There's no cloud or hosted version — crawl data stays on your machine, unlike some competitors that offer a cloud tier for scheduled team audits.
