Capabilities and scope
| Capability | Screaming Frog | WebAuditOS |
|---|---|---|
| Crawl workflow | Desktop SEO crawler | Hosted public-website scans |
| Custom extraction | Documented licensed feature | No configurable XPath extraction interface |
| JavaScript rendering | Licensed feature | Browser pass with evidence and coverage reporting |
Where Screaming Frog can be the better fit
Choose Screaming Frog when you need direct control over crawl configuration and custom extraction. Its desktop investigation workflow is a different fit from a hosted audit workspace.
When WebAuditOS fits
Use WebAuditOS when you want a public website crawl with traceable findings, page evidence, category scores and a documented boundary between automated results and manual review. Plans change crawl capacity and the available workflow features. A scan cannot certify legal compliance, complete accessibility or private server configuration.
Compare the same representative pages and important journeys. Check which observations each tool makes, which states it cannot reach and how a resolved issue is verified. Match the tool to that task before comparing headline scores or check counts.
