How does CodeFrog compare to Screaming Frog?

CodeFrog and Screaming Frog SEO Spider are both desktop apps for website analysis, but with different strengths. Both use the axe-core accessibility engine.

• CodeFrog adds: OWASP security scanning, W3C HTML validation, code analysis (secrets detection, supply chain vulnerabilities, static analysis), Open Graph/Twitter Card validation, and a unified Mega Report with A–F health grades.
• Screaming Frog adds: Unlimited URL crawling, broken link detection, duplicate/near-duplicate content detection, redirect chain analysis, JavaScript rendering via Chromium, spelling/grammar checks, AI/LLM integration, and Google Analytics/Search Console integration.
• Both offer: axe-core accessibility testing (WCAG AA/AAA), on-page SEO checks, desktop app, and localhost/dev domain testing.

Note: Full WCAG AA/AAA conformance requires manual testing with assistive technologies beyond what any automated tool provides. See CodeFrog's WCAG page for details.

CodeFrog is $99/year; Screaming Frog is free for 500 URLs or $279/year for unlimited crawling. Use both together for comprehensive coverage.
