Safari Web Debugger

The tool provides a multi-field workflow for evaluating Safari feature support. Users enter one or more web features (for example CSS container queries, JS APIs, or CSS features) and specify a Safari version or version range. The system consults a curated compatibility dataset mapped to Safari release history and standard web platform definitions to determine a clear status: Supported, Partially Supported, or Not Supported, with version-specific notes. Batched inputs allow assessing multiple features in a single run for engineering handoffs and release planning.
Output data includes: status per feature, recommended polyfill or fallback, and a progressive enhancement path. Optional advanced inputs enable risk scoring, minimum viable support thresholds, and targeted testing scope. The tool outputs a concise report with per-feature rationale and a summary suitable for tickets and stakeholder updates.
Intended users are web developers, QA engineers, and product managers focusing on Safari parity across macOS and iOS. Use cases include evaluating new CSS or Web API features before release, comparing Safari coverage against other browsers, and planning polyfills or light-weight shims. The differentiator is a combination of version-aware outputs, actionable guidance, and batch-processing capability that accelerates compatibility decisions without running live browser tests.
