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 makes it suited to broad technical reviews rather than just link checks. The trade-off is that it is desktop software for Windows and macOS, not a web-based crawler.

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.

Key features

JavaScript crawling: Chromium rendering allows Spider to crawl JavaScript pages, which matters when a site’s content or links depend on client-side rendering.
Scraping: The built-in scraper supports up to 15 conditions and four search types: contains, Regexp, XPath, and CSS. That gives users several ways to extract page data without treating the crawler as only an issue detector.
Audit and sitemap tools: Internal PageRank calculation, source-code and HTTP-header checks, plus sitemap generation and validation, make it useful across several technical SEO tasks.
Integrations and exports: Google Analytics and Google Search Console integrations, CSV import, and exports to Google Drive and Sheets can fit Spider into reporting workflows. Reports can also be exported as CSV, XLSX, or PDF; PDF audits can carry a company logo, contact details, and recommendations, making them more suitable for client-facing work.
Privacy: Netpeak Software says it does not sell personal data and processes it in compliance with EU GDPR. Its privacy policy also says service providers must meet data-protection and security standards, keep shared information confidential, and follow processing instructions.

Pricing

Netpeak Spider is freemium and offers a 3-day trial. The Netpeak Spider Free plan costs 0.00 USD per free and allows 500 URLs, 5 threads, and 2 devices per user on Windows or macOS. That is enough for smaller crawls, but the URL and thread ceilings limit its usefulness for regular audits of larger sites.

Netpeak Spider Pro Monthly costs 20.00 USD per month, billed 1 month. It raises capacity to unlimited URLs and 200 threads, with one user and two devices on Windows or macOS. For ongoing work, Netpeak Spider Pro Yearly costs 193.00 USD per year, billed 1 year; the page also shows $240. It includes the same one-user, unlimited-URL, 200-thread, two-device allowance. The lower annual price suits users who expect to keep the software, while the monthly plan avoids a year commitment.

Netpeak Spider Pro Lifetime costs 496.00 USD per once, billed forever, with the same Pro allowances. It is the option for users who prefer a one-time payment over monthly or annual billing. Separate Monthly, Yearly, and Lifetime Pro entries also describe one user, unlimited URLs, and 200 threads but have no published price. Across the listed Pro plans, the single-user allowance makes Spider a better fit for an individual specialist than a multi-seat team purchase.

Platforms

Spider runs on Windows and macOS. That desktop availability is useful for people who want a local crawling workflow on either system, but it rules it out for readers seeking a browser-based tool or Linux support.

Who it's for

SEO specialists, webmasters, developers, and QA teams are the clearest fit when they need technical checks, JavaScript crawling, or structured-data audits. Link builders, marketing and content teams, sales teams, PPC specialists, and bloggers are also among the product’s intended audiences, though the strongest case is for users whose work depends on crawling and reviewing site-level issues. The free plan can serve small sites or occasional checks; larger audits call for Pro.

Pros and cons

Pros:
- More than 100 technical checks, including structured data, broken links, canonicals, and pagination, provide broad audit coverage in one desktop tool.
- Chromium rendering and a scraper with 15-condition capacity and four query types extend its usefulness beyond conventional crawling.
- Unlimited URLs and 200 threads on Pro remove the free plan’s main crawl-size constraints.
- CSV, XLSX, PDF, Google Drive, and Sheets exports support both internal analysis and branded audit reporting.
Cons:
- The Free plan stops at 500 URLs and 5 threads, which can restrict larger site reviews.
- Pro is limited to one user, so teams needing multiple individual seats may need another arrangement.
- Windows and macOS support excludes browser-only and Linux workflows.

Alternatives

Screaming Frog SEO Spider is the closest alternative for readers who want a crawler with a free 500-URL crawl on Windows, macOS, or Linux, and an unlimited-URL paid licence.

Ahrefs is a better direction for readers who want web-based SEO data and limited Site Explorer and Site Audit access on its free plan, rather than a desktop crawler.

Semrush may suit readers who want a web-based SEO platform with a free tier limited to one demo project and 10 reports per day.

Mangools is another freemium SEO option for readers comparing broader SEO software instead of a Windows or macOS crawler.

SEO PowerSuite is worth considering for readers who want a free desktop SEO toolkit allowance of one project, 500 URLs, 1,100 backlinks, and one competitor per project.

SpyFu is an alternative for readers focused on web-based search and keyword data, with a Basic plan at 39.00 USD per month.

Moz Pro is a web-based, paid option with a free trial and a 49.00 USD monthly Starter plan for individuals managing one website.

SiteGuru suits readers looking for a web-based option whose Small plan covers 5 websites and 5,000 pages per site for 49.00 USD per month.

Readers comparing category options can also browse SEO Analytics Software, SEO Audit Software, SEO Crawler Software, Technical SEO Software, and SEO tools.

Verdict

Netpeak Spider is a strong choice for an individual SEO specialist or site team member who needs deep technical crawling, JavaScript rendering, scraping, sitemap tools, and report exports in one Windows or macOS application. Its free plan is viable for modest crawls, while Pro removes the URL ceiling and raises thread capacity sharply. Look elsewhere if you need a web-based or Linux workflow, or a multi-user plan.
