SpiderNow

Overview

SpiderNow is a website crawler and real-time site-audit service for people who need to examine individual pages, folders, or whole websites. It suits developers, SEO agencies, digital marketers, and businesses that want technical checks alongside practical web utilities. Its breadth is useful for diagnosing and fixing site issues, while device-memory limits and modest free-plan allowances make larger recurring crawls a paid-plan decision.

Key features

Crawl scope can be tailored from one page to a full site. Checks include broken links and images, JavaScript sites, redirects, duplicate content, internal and external links, and robots directives. That makes SpiderNow useful for technical cleanup and site reviews, but it does not cover keyword research, rank tracking, backlink analysis, or competitor research. Teams needing those research functions will need another tool.

PageSpeed Insights analysis covers Performance, Accessibility, Best Practices, and SEO. Alongside crawl findings, these page-level checks help teams assess several aspects of a page in one workflow. Coding utilities minify and beautify HTML, JavaScript, and CSS, generate critical CSS, and convert images to WebP. They are useful companion tools for developers, though the product is not presented as a replacement for a development environment.

AI tools can recommend or implement content changes, subject to the site's add-on terms. The content-improvement feature uses Grammarly for spelling and grammar corrections. This may suit teams making content edits as part of site maintenance, but the add-on terms matter when budgeting or depending on AI features.

SpiderNow requires no software download and says it works on mobile, iPad, and desktop devices. Crawl size depends on device RAM because processing uses device memory, so hardware can constrain the scope of a scan. The FAQ says accounts and data are protected with SSL encryption and payments are secured through Stripe. It also says support is available around the clock and usually responds within a few hours. API access is marked as a feature, while the FAQ says API services are being built and will be available shortly; users who need a working API now should confirm availability before choosing it.

Pricing

SpiderNow uses a freemium model, with monthly plans that add full-site scan capacity, AI credits, and saved scans. Unlimited projects and websites on paid tiers remove project-count restrictions, but scan quotas and saved-scan caps still shape how much work can be managed at once.

The free plan has no time limit, requires no credit card, and receives monthly usage refills. Its 10 single-page scans and limited access to scan details and metrics make it best for occasional checks, not ongoing whole-site auditing. Basic is the lowest-cost paid option for smaller workloads that need full-site scans; its 500-scan allowance, 10 AI credits, and two saved scans are tighter than higher tiers. Standard raises those limits for regular site work. Advanced is aimed at users with substantially higher scan volumes, with 15,000 scans and the largest listed allowances. A free trial is not offered, so paid use begins at the monthly plan price.

Platforms

SpiderNow supports Android, iOS, web, and extension platforms, as well as API access. Its no-download approach and stated mobile, iPad, and desktop support suit users who want to work across devices. The device-memory dependence still means available hardware can affect crawl size.

Who it's for

SpiderNow is a sensible fit for web developers and SEO practitioners who want technical crawl checks, PageSpeed analysis, and coding utilities together. Agencies and businesses can use the paid tiers when their monthly crawl volumes exceed the free allowance. It is a weaker fit for SEO teams whose core needs are keyword discovery, rank monitoring, link analysis, or competitor research, since those capabilities are absent.

Pros and cons

Pros

• Scans can target a page, folder, or full site, supporting both focused troubleshooting and broader reviews.
• Technical checks, four PageSpeed audit areas, and coding utilities bring diagnosis and practical page tools into one service.
• The free plan is ongoing, has monthly refills, and requires no credit card.
• Paid plans include unlimited projects and websites, with scan and AI allowances that increase by tier.
• It works across mobile and desktop devices without a software download.

Cons

• Crawl size depends on device RAM, which can limit larger scans on less capable devices.
• The free tier allows only 10 single-page scans monthly and restricts access to scan details and metrics.
• It lacks keyword research, rank tracking, backlink analysis, and competitor research, so it cannot cover those broader SEO workflows.
• API services are described as still being built, which may make API access unsuitable for users who need it immediately.
• AI content changes are subject to add-on terms, so the listed plan allowances alone do not describe their full cost.

Verdict

Choose SpiderNow if you want a browser-accessible crawler that pairs technical audits with PageSpeed checks and useful coding tools, and your device can handle the crawl size you need. The free tier is suitable for light use, while paid plans scale to larger scan volumes. Look elsewhere if your work depends on broader SEO research, if you need dependable large crawls on limited-memory hardware, or if API services must be ready now.
