SiteCurl vs. Google Lighthouse: When to Use Which

Different tools for different jobs

Google Lighthouse is a free, open-source tool built into Chrome DevTools. It audits a single page at a time and scores performance, accessibility, SEO, and best practices on a 0-100 scale.

SiteCurl scans up to 50 pages per site across 58 checks in 7 categories, tracks scores over time, and generates shareable reports. It’s built for ongoing monitoring, not one-off spot checks.

Both are useful. They serve different purposes.

Where Lighthouse excels

• Free and built into Chrome: No signup, no cost. Open DevTools and run it.
• Performance profiling: Detailed performance traces with filmstrip view, main thread breakdown, and treemap visualization.
• Developer workflow: Great for debugging specific pages during development.
• PWA checks: Progressive Web App audits that SiteCurl doesn’t cover.

Where SiteCurl adds value

• Multi-page scanning: Audit 10-50 pages in one scan instead of running Lighthouse page by page.
• Score tracking over time: See how your site health changes week over week.
• Automated scheduling: Set weekly or monthly scans. No manual runs needed.
• Shareable reports: Send a link or export a PDF. Useful for client reporting.
• AI Readiness checks: Structured data validation and AI search readiness scoring that Lighthouse doesn’t include.
• Score drop alerts: Get notified when something regresses between scans.

When to use Lighthouse

Use Lighthouse when you’re actively developing and need to debug a specific page. Run it in Chrome DevTools, review the performance trace, and optimize.

When to use SiteCurl

Use SiteCurl when you need to monitor a live site over time, audit multiple pages at once, or share results with someone who doesn’t use Chrome DevTools.

Using them together

Many teams run SiteCurl for scheduled monitoring and Lighthouse for deep-dive debugging. SiteCurl catches regressions across the site. Lighthouse helps you investigate and fix them.
