In their own words
Crawlr
Crawlr is a website crawler and technical SEO audit tool that finds technical issues, crawl inefficiencies and site architecture problems. It discovers URLs through internal links, sitemaps, canonical links and JavaScript. Crawl settings include robots.txt compliance, rate limiting, inclusion and exclusion rules, and depth controls. Its analysis covers response codes, indexability, metadata, headings, word counts, and internal and external links. Results can be explored through interactive graphs, directory trees, 3D site views and content-cluster visualizations. Crawls can run daily, weekly or on custom schedules, with email notifications on completion. The API can start crawls, check their status, return structured JSON, access historical data and send webhook events. The Free plan is free and includes 500 tokens monthly, one concurrent crawl, CSV and JSON exports, and 15-day history. Paid plans start at $8/mo (annual). The Starter plan lists 5,000 tokens monthly, five concurrent crawls and a 5,000-page maximum per crawl. Unauthenticated sandbox crawls are limited to 25 pages.
