What to expect from an ideal product

  1. SanityCheck lets you write web app tests in plain English, no code or QA scripts needed, and AI agents handle the rest inside real cloud browsers.
  2. Tests run automatically on every GitHub, GitLab, or Vercel deploy, so broken flows get caught before users ever see them.
  3. Watch your AI agent click through your app live, or replay every step after the fact to pinpoint exactly where something broke.
  4. No credit card required to start, making it practical for solo developers and small teams who need real user simulation without the overhead.
  5. Instead of maintaining brittle Selenium or Playwright scripts, you describe the user journey once and SanityCheck keeps testing it on every push.
