In their own words
Oncrawl
Oncrawl is a technical SEO analysis platform that combines website crawl data, server logs, and performance metrics. Its crawler examines site structure, content, performance, and internal linking, supports JavaScript rendering, and is described as handling millions of URLs. The Log Analyzer shows how search engines, AI bots, and users interact with a site through real server logs. Teams can schedule crawls, compare results, and receive alerts about technical changes or regressions. AI bot monitoring and analysis lenses address AI search visibility and content quality at scale. Connectors include Google Search Console, GA4, Majestic, and Piano; logs can be ingested from Cloudflare, Google Cloud Platform, AWS, Azure, or direct files. The REST API can trigger crawls, manage projects, and export data to BI tools, warehouses, Google Data Studio, and Dataïku. Oncrawl states ISO 27001, SOC 2 Type I and II, GDPR, and CCPA compliance. Pricing is quote-based.
Screaming Frog SEO Spider
Screaming Frog SEO Spider crawls websites to audit more than 300 SEO issues and support improvements to search performance and user experience. It finds broken links and server errors, checks redirects, and flags page titles and meta descriptions that are missing, duplicated, or too long. For JavaScript-heavy sites, it can render pages with its integrated Chromium WRS, including sites using Angular, React, and Vue.js. Data extraction supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, with link-metrics integrations for Majestic, Ahrefs, and Moz. Crawls can be scheduled, automated from the command line, exported to destinations such as Google Sheets, and compared across runs or between staging and production. The free version costs nothing and allows 500 URLs per crawl; saving crawls, configuration, and advanced features are restricted. The paid version costs $279 a year per licence, with unlimited crawl size subject to allocated memory and storage. It runs on Linux, macOS, and Windows.
