What types of tools does Krawly offer?

Krawly offers tools in 11 categories: SEO (meta tag validator, heading analyzer, keyword density, core web vitals), Web Scraping (email scraper, table extractor, CSS selector scraper), Security (SSL checker, port scanner, WordPress scanner), OSINT (DNS lookup, WHOIS, IP geolocation), E-Commerce (Amazon scraper, Shopify scraper, price tracker), YouTube (comments scraper, playlist extractor, thumbnail downloader), Developer (JSON formatter, regex tester, JWT decoder), Content (word counter, readability score), Analysis (technology detector, page speed analyzer), Social Media (TikTok analyzer, Instagram analyzer), and Utilities (QR code generator, URL shortener).

Is Krawly a good alternative to SEMrush, Ahrefs, or BuiltWith?

Krawly provides many of the same on-page SEO analysis features as SEMrush and Ahrefs for free, including meta tag validation, heading analysis, keyword density checking, and structured data auditing. For technology detection, it serves as a free alternative to BuiltWith and Wappalyzer. However, Krawly focuses on individual page analysis rather than domain-wide crawling or backlink databases.

Can I use Krawly for lead generation?

Yes. Krawly's Lead Generation tool automatically crawls a website's homepage, about, contact, and team pages to extract email addresses, phone numbers, LinkedIn profiles, Twitter handles, Facebook pages, Instagram accounts, and GitHub links. Results can be exported as JSON, CSV, or Excel.

Does it work with @handles?

Yes, enter either a YouTube channel URL (youtube.com/@handle, youtube.com/c/channelname, or youtube.com/channel/ID) or just the @handle.

How many recent videos does it show?

The tool typically shows the most recent 10-30 videos depending on the channel's page structure.

Is subscriber count always available?

Most channels show subscriber counts publicly, but some creators choose to hide this. The tool extracts what's publicly visible.
