Start With an Optimized Baseline
Website Accessibility Checker with Performance Audits, SEO & AI Audits, and More
Coming Spring 2026! BetaSweep is a full-site website quality scanning app for macOS, Windows, and Linux that analyzes accessibility, performance, SEO, HTML validity, and content quality across every page of your site. Designed to establish—and re-establish—a clear baseline, BetaSweep helps teams catch critical issues early, validate ongoing improvements, and maintain accessible, fast, and search-ready websites over time. The app runs locally, puts you in control of your data, and lets you pay per scan with no subscriptions or lock-in.
