What are the limits of HAR Network Analyzer?
Up to 5 MB / 5,000 HTTP Archive entries. Timing phases with -1 are unavailable, not zero; SSL is a subset of connect and is not double-counted. Body size excludes headers and may be unavailable. HAR files can contain credentials; processing and export stay local. This inspects an uploaded capture, not live site performance. Text input: 5 MB total. XML external entities and includes are disabled. No automatic local storage. Reports summarize the selected result; CSV/JSON retain complete records.
