Description
Network analysis with sanitized HAR, retention limits, integrated search, accessible UI, and keyboard controls. Network+ for DevTools adds a dedicated network-analysis panel to Google Chrome DevTools. It is designed for web developers, QA engineers, and support engineers who need to inspect HTTP evidence without leaving the DevTools workflow. The request grid captures traffic reported by the Chrome DevTools network API and presents method, status, domain, path, type, duration, size, initiator, URL, and optional waterfall information. Users can sort and resize columns, choose visible columns, apply per-column filters, save filter presets, and search across URLs, headers, request bodies, and response bodies. Selecting a request opens request and response inspectors for headers, bodies, query parameters, cookies, raw data, timing phases, and supported previews. Two selected requests can be compared side by side. Network+ applies bounded local retention. The default request limit is 20,000, configurable from 100 to 100,000; an explicitly confirmed unlimited request mode is also available. Response bodies remain subject to a 1 MiB per-body limit and a 32 MiB shared cache limit. The status bar reports retention and body-cache conditions so omitted or evicted content is not presented as complete evidence. Clear removes the current working set and offers a bounded 10-second Undo action while retained data remains available. Clipboard copy and HAR export are user-initiated. Sanitized output is the default and redacts or omits sensitive fields according to the documented policy. Full output requires a warning and one-time confirmation for that action, and Network+ does not save a full-output preference. Users should still review any exported or copied data before sharing it. An empty panel offers three deterministic, local-only sample requests under reserved `.test` domains. The sample sends no network traffic, pauses live capture to avoid mixing evidence, and includes a prompt-first guide for identifying a 503 request, its dominant Wait (TTFB) phase, a Retry-After header, and the limits of browser-observed timing. No account or test credentials are required. Network+ supports System, Dark, and Light themes, keyboard navigation, visible focus, screen-reader status announcements, responsive panel layouts, and reduced-motion preferences. It runs from packaged extension code without remote code, telemetry, analytics, advertising, or an external service. Network+ reports browser-observed HTTP timing; it does not prove packet loss, cabling or radio-frequency faults, or a definitive server root cause. Every feature is free. Optional GitHub Sponsors and Ko-fi links open in ordinary browser tabs; the extension embeds no checkout and receives no payment or account data.
