New to DiffChecker Pro?
Start with "Your First Comparison" — it takes less than 5 minutes and covers all the basics.
Learn how to paste two text files, run a diff, understand the highlighted results, and navigate between changes. The perfect starting point.
Capture API responses from staging and production, paste them into DiffChecker Pro's JSON diff mode, and use structural comparison to identify breaking changes.
Build a comparison workflow that runs on every CI pipeline — capturing baseline snapshots, comparing API responses, and failing the build when unexpected changes are detected.
Authenticate with your API key, make your first comparison request using cURL or JavaScript, parse the response, and generate a shareable link programmatically.
Add DiffChecker Pro to your GitHub Actions workflow to automatically compare generated files, API schemas, and configuration against committed baselines on every PR.
Generate schema dumps from two MySQL or PostgreSQL databases, compare them in DiffChecker Pro's SQL diff mode, and use the result to write safe migration scripts.
Upload two PDF documents (contracts, reports, policy files) to DiffChecker Pro, navigate the visual diff by page, and export a comparison report.
Create a shareable diff link, customize expiry settings, share with teammates who don't have accounts, and use the Team plan's access controls for sensitive diffs.
