Web scraping pipelines break silently all the time. Either the layout changes, Cloudflare blocks you, or the target site serves partial DOM structures. When scraping thousands of pages daily, silent schema failures cost time and money.
To solve this, I built a zero-dependency Scraper Sanity Checker web utility as part of a lightweight developer tool suite.
Key Features of the Utility:
- Schema Drift Detection: Validates expected vs actual field occurrences.
- Data Completeness Index: Measures null/missing fields against threshold baselines.
- Zero External Dependencies: Pure client-side JavaScript, zero data logging or tracking.
You can try the live interactive tool here: Scraper Sanity Checker
