Crawler control, engineered precisely.
Precision instruments for the two files that decide how search engines crawl and index your site — XML sitemaps and robots.txt. Generate, validate, test and export, all in-browser, no signup.
Sitemap Pro
Generate, validate, split and index XML sitemaps — with limit checks (50k/50MB), changefreq/priority and full stats. In-browser.
OpenRobots.txt Pro
Build, validate and test robots.txt — real longest-match URL testing with * and $ wildcards, per-user-agent groups and sitemap directives.
OpenCharacter Counter & Writing Analyzer
Live characters, words, sentences, reading time, Flesch readability, keyword density, social & SEO character limits, goals and language detection. Private, in-browser.
OpenA clean, valid sitemap helps search engines discover every URL — and split/index for sites past the 50k limit.
A correct robots.txt keeps crawlers out of the paths you choose — tested before you deploy a costly mistake.
Catch invalid loc, bad priorities, conflicting rules and deindex-the-whole-site errors ahead of time.
Everything runs in your browser — paste internal URLs and rules with nothing uploaded.
