The setup most crypto SEO consultants run
Screaming Frog ($259/year) for technical audits with custom extraction tuned to client sites. Crawlux Pro ($25 per audit) for the crypto-tuned audit layer. Combined ~$359/year covers both.
The free tiers also complement each other. Screaming Frog free covers up to 500 URLs without JS rendering. Crawlux free covers 2 of 8 modules without URL limits. For small crypto sites under 500 URLs, the combined free coverage is meaningful.

Common questions
Pricing accurate as of April 2026 from screamingfrog.co.uk.
Is Crawlux a replacement for Screaming Frog?
No. Screaming Frog SEO Spider has been the industry-standard desktop technical SEO crawler since 2010. It excels at raw crawl power, custom XPath and regex extraction, JavaScript rendering and integrations with Google Analytics, Search Console, Majestic and Ahrefs. Crawlux is a hosted crypto-focused audit tool that does not crawl unlimited URLs or expose custom extraction. Most crypto teams running serious technical SEO use Screaming Frog and Crawlux together rather than swapping one for the other.
What does Screaming Frog miss that Crawlux catches?
Screaming Frog covers technical crawl: broken links, redirect chains, page titles, meta descriptions, headers, canonical, robots.txt, JavaScript rendering, custom extraction. It does not cover crypto-specific signals: FinancialProduct or CryptoExchange schema validation in context, GoPlus smart contract security, Web3 Backlink Toxicity Rubric, AEO citation testing on crypto category prompts, audit firm citation tracking. Screaming Frog parses JSON-LD generically; Crawlux validates whether you used the right schema type for the page intent.
How does the pricing compare?
Screaming Frog is $259/year per workstation license, with a free version capped at 500 URLs. Crawlux is one-time per domain: Free $0, Pro $25, Team $49 (3 seats included). For a single user auditing one site quarterly, Screaming Frog at $259/year vs Crawlux Pro at $100/year (4 audits) is comparable in cost but covers different scope. Most crypto teams running both find the combined cost (~$359/year) reasonable for full technical plus crypto coverage.
Should I use both?
Yes, this is the most common setup for SEO professionals doing crypto work. Screaming Frog ($259/year) for the deep technical crawl with custom extraction tailored to your site. Crawlux Pro ($25 per audit) for the crypto-specific audit layer. The two tools do not overlap meaningfully. Screaming Frog gives you raw technical data; Crawlux gives you crypto-tuned audit findings with copy-paste fixes. Most crypto SEO consultants run both as part of their standard workflow.
Does Crawlux have custom extraction like Screaming Frog?
No. Custom XPath and regex extraction is one of Screaming Frog's strongest features and a real reason to keep using it. Crawlux runs a fixed analyzer suite tuned for crypto signals; you cannot define custom extractors. If you need to extract specific data points from your site that Crawlux does not cover (custom price displays, custom badge content, specific data attributes), Screaming Frog is the right tool for that workflow.
What about the free version of Screaming Frog?
Screaming Frog free version crawls up to 500 URLs and includes most core features but no JavaScript rendering, no custom extraction, no Search Console integration and no scheduled crawls. For small crypto sites under 500 URLs, the free tier covers basic technical needs. For sites larger than that, the $259/year paid version is required. Crawlux Free tier is unrestricted on URL count but covers fewer module dimensions (2 of 8); the two free tiers complement each other reasonably for small sites.
Is Screaming Frog better for crypto than Sitebulb?
Different tools for different workflows. Screaming Frog is more raw-data oriented, more configurable, more powerful for large sites and unique extraction needs. Sitebulb is more visual, more beginner-friendly, hint-driven with prioritized recommendations. Pricing is comparable: Screaming Frog $259/year vs Sitebulb Lite $165/year. Neither covers crypto-specific signals; both pair well with Crawlux. Pick the one that matches your style; the technical SEO output is similar in coverage. See Crawlux vs Sitebulb for that side-by-side.
How does the JavaScript rendering compare?
Both use Chromium-based JavaScript rendering. Screaming Frog renders every URL in the crawl when JS rendering mode is enabled (paid tier required). Crawlux uses Puppeteer to render representative pages per template. For a 10,000-URL crypto site needing every URL rendered, Screaming Frog is the better tool. For checking how AI bots see your site (with the 69% of AI crawlers that cannot run JS in mind), Crawlux explicitly tests both rendered and unrendered versions, which Screaming Frog does not.
