SpiderNow combines site crawling, technical audits, PageSpeed analysis, and coding utilities. Its free plan offers a limited monthly allowance, while paid plans start at $6.99 a month.

SpiderNow is described as a fit for SEO agencies, web developers, digital marketers, and businesses. It may suit people who need site audits and coding tools without installing software.

Overview

SpiderNow is a website crawler and technical audit service for SEO agencies, developers, digital marketers, and businesses. It is best suited to people who need crawl diagnostics alongside page performance checks and small coding utilities. Its broad tool mix is useful for website maintenance, though device memory can limit how much a crawl handles at once.

Key features

Scans can target a single page, a folder, or a whole website, so SpiderNow can serve both a focused check and a broader review. Its audit checks include broken links and images, JavaScript sites, redirects, duplicate content, internal and external links, and robots directives. That makes it a capable technical crawler, but it does not cover keyword research, rank tracking, backlink analysis, or competitor research. Teams looking for a complete SEO research suite will need another tool alongside it.

PageSpeed Insights analysis covers Performance, Accessibility, Best Practices, and SEO. This gives users a way to assess page quality as well as crawl issues. The included utilities minify and beautify HTML, JavaScript, and CSS, generate critical CSS, and convert images to WebP. They are convenient companions for web work, although they do not replace a full development environment.

AI tools can recommend or implement content changes, subject to add-on terms. The content improvement feature uses Grammarly for spelling and grammar corrections. These tools may help with routine edits, but the add-on terms matter for teams that plan to depend on AI features.

SpiderNow runs without a software download and says it can be used on mobile, iPad, and desktop devices. Crawl size depends on the device's RAM because processing uses device memory; large site audits may therefore be less predictable across devices. The free subscription has no time limit, requires no credit card, and receives monthly usage refills. The FAQ also says accounts and data are protected with SSL encryption, payments are secured through Stripe, and support is available around the clock, usually replying within a few hours. API access is presented as a capability, while the FAQ says API services are still being built and will be available shortly.

Pricing

SpiderNow's free plan is free, billed Free forever. It includes 10 single-page scans per month, 5 scan detail and issue views, and 5 page metric scores. The no-time-limit access is useful for occasional checks, but the monthly scan and report-view caps make it a narrow evaluation or light-use option.

Basic costs $6.99 a month and includes 500 full website scans, unlimited projects and websites, 10 AI credits, and 2 saved scans. It is the entry paid tier for an individual or small operation that needs full-site scans, but the two saved scans may constrain ongoing comparisons.

Standard costs $19.99 a month for 2,000 full website scans, unlimited projects and websites, 20 AI credits, and 3 saved scans. It suits users with more frequent crawl needs, though the increase in scan volume comes with only one additional saved scan over Basic.

Advanced costs $39.99 a month and provides 15,000 full website scans, unlimited projects and websites, 50 AI credits, and 6 saved scans. This is the strongest fit for heavier audit workloads; the main step up is scan capacity, while saved-scan and AI-credit allowances also rise. The listed paid plans are monthly, and the free plan is the only one with an explicitly stated no-time-limit term.

Platforms

SpiderNow lists Android, iOS, web, extension, and API platforms. Its no-download access and stated mobile, iPad, and desktop support make it flexible for users switching devices. The FAQ's note that API services are still being built means API availability may not match the platform listing yet.

Who it's for

SpiderNow is a practical fit for agencies and web teams that want technical site checks, PageSpeed analysis, and basic code or image utilities in one service. It is less suited to marketers whose work depends on keyword discovery, rank monitoring, backlinks, or competitor analysis, since those capabilities are absent. Device-memory-based crawling is also a consideration for users auditing especially large sites.

Pros and cons

• Pros: Scans range from individual pages to full websites, supporting both targeted troubleshooting and site-wide checks.
• Pros: Technical audits and PageSpeed categories cover a useful mix of crawl and page-quality concerns.
• Pros: The free plan has no expiry or credit-card requirement and refreshes usage monthly.
• Cons: Crawl size depends on device RAM, which can limit large audits.
• Cons: The free plan's 10 monthly scans and limited detail and metric views restrict regular analysis.
• Cons: It lacks keyword research, rank tracking, backlink analysis, and competitor research, and its API services are still being built.

Alternatives

SEO Crawler Software and SEO tools are useful starting points for comparing options across those categories.

Choose Crawlr if a free web and API crawler with 500 monthly tokens, one concurrent crawl, full-site crawling, SEO intelligence, CSV and JSON exports, and 15-day crawl history better matches your needs.

Netpeak Spider is an alternative for users who want a desktop crawler for Windows or macOS, with a free plan covering 500 URLs, five threads, and two devices per user.

Consider A1 Website Analyzer if you prefer a Windows or macOS tool with a free mode that continues after a 30-day evaluation period.

CrawlX may suit users seeking a web and API crawler with 500 URLs per crawl, five monthly crawls, one project, 150+ SEO checks, and CSV, JSON, and PDF exports on its free plan.

Pick LibreCrawl if MIT-licensed, self-hosted open-source software is the priority.

Screaming Frog SEO Spider is another option, with a free crawl limit of 500 URLs and a paid licence for unlimited URLs.

VisRankBot is worth considering for a free visibility score, category breakdown, and top three issues without an account, with a full report priced at $10, paid once.

WebCrawler Pro is another crawler option.

Verdict

SpiderNow is a strong match for web teams that want technical crawling, PageSpeed checks, and practical coding utilities together, with a free tier for occasional use and paid plans that scale scan volume. Choose it when those combined maintenance tools matter more than broader SEO research. Look elsewhere if you need keyword, rank, backlink, or competitor analysis, or if device-dependent crawl capacity is a poor fit for your audit workload.
