Try CrawlOut
All toolsSitemap & Robots.txt Checker

Make sure both files agree

CrawlOut fetches your robots.txt and every sitemap it references, validates both against the real specs, spot-checks a sample of listed URLs for reachability, and flags any page your sitemap tells crawlers to index while robots.txt tells them not to fetch.

No install, no login — results in under a minute.
