Overview

The crawler examines status codes, redirects, structured data, tags, site structure, and other on-page SEO details. It detects more than 100 technical issues, including broken links, duplicate pages, faulty meta tags, canonical issues, and pagination problems. That scope makes it useful for recurring technical audits, while its desktop-only availability rules it out for teams that require a web platform.

Netpeak Software is headquartered in London. The company says its products were developed in 2010 and that it has operated independently from Netpeak Agency since 2016. Support includes a knowledge base, Help Center tickets that usually receive a response within 24 hours on working days, and automatic software updates. Netpeak Software says it does not sell personal data and processes it in compliance with EU GDPR.

Key features

JavaScript crawling: Chromium rendering lets Spider crawl JavaScript pages, helping teams audit pages whose content or links depend on rendering.
Built-in scraper: Up to 15 conditions and four search types—contains, Regexp, XPath, and CSS—give users ways to extract targeted page data without limiting the tool to standard audit checks.
Audit utilities: Internal PageRank calculation, source-code and HTTP-header checks, and sitemap generation and validation extend its use beyond issue detection.
Integrations and reporting: Google Analytics and Google Search Console integrations, Google Drive and Sheets exports, and CSV import connect crawl work with other data. Reports export to CSV, XLSX, or PDF; PDF audits can include a company logo, contacts, and recommendations, which is useful when delivering client-facing findings.

Pricing

The Free plan is free and includes 500 URLs, 5 threads, and 2 devices per user on Windows and macOS. That is enough for small sites or limited checks, but the URL cap makes it a poor fit for full audits of larger sites. A 3-day trial is also offered.

Pro provides unlimited URLs and 200 threads, but each listed paid plan is for 1 user. Netpeak Spider Pro Monthly costs 20.00 USD per month, billed 1 month; it suits users who need higher crawl capacity without a longer commitment. Netpeak Spider Pro Yearly costs 193.00 USD per year, billed 1 year; the page also shows $240, so buyers should note both figures when considering the annual option. Netpeak Spider Pro Lifetime costs 496.00 USD per once, billed forever, for users who prefer a one-time payment over recurring billing. Each of these priced plans includes 2 devices per user and Windows and macOS support.

Other Monthly, Yearly, and Lifetime Pro plan entries show custom pricing and the same 1-user, unlimited-URL, 200-thread allowance, without device or platform terms. For multi-person teams, the one-user paid plans are a notable constraint.

Platforms

Netpeak Spider runs on Windows and macOS. There is no web platform in its supported platforms, so it is best suited to individual desktop workflows rather than teams that need browser-based access.

Who it's for

SEO specialists, webmasters, link builders, and marketing or content teams can use it for technical audits and crawl-based analysis. Developers and QA teams may value the source-code, HTTP-header, and JavaScript checks; sales, PPC, and blog users are also among the audiences Netpeak identifies for its products. It is less suitable for organizations that need multiple paid user seats or a web-first workflow.

Pros and cons

Pro: More than 100 technical checks cover a broad range of routine audit concerns, including structured data and pagination.
Pro: JavaScript rendering, scraping, and internal PageRank calculation give it uses beyond a basic URL crawl.
Pro: Multiple export formats and branded PDF audits help turn crawl findings into shareable reports.
Con: The free plan's 500-URL and 5-thread caps restrict its usefulness for larger or faster crawls.
Con: Paid plans cover one user, limiting their fit for teams that need shared individual accounts.
Con: Windows and macOS only excludes users who need a web-based crawler or another desktop platform.

Alternatives

Screaming Frog SEO Spider is a close alternative for desktop crawling: its free version also caps crawls at 500 URLs, while its paid licence provides unlimited URLs. Ahrefs is worth considering for users who want web and API access, a free plan with data about their own site, and limited Site Explorer and Site Audit access. Semrush offers a free plan with one demo project and 10 reports per day, making it an option for readers whose needs fit those limits.

Labrika, Moz Pro, SiteGuru, WooRank, and Click Insights are other options to compare. Browse SEO Crawler Software, Technical SEO Software, SEO Audit Software, SEO Analytics Software, and SEO tools for more choices.

Verdict

Choose Netpeak Spider if you need a Windows or macOS crawler that combines broad technical checks with JavaScript rendering, scraping, and detailed exports. Its free tier is a useful starting point for small crawls, but 500 URLs is a firm ceiling; larger audits need Pro, and the one-user paid plans are a reason for teams to consider another tool.
