HTTP Archive (HAR) Waterfall Analyzer
Inspect browser network captures client-side with interactive latency waterfall timelines, status breakdowns, and security vulnerability scans.
Export a .har file from Chrome, Safari, or Firefox DevTools Network tab and drop it here. Inspect TTFB, DNS lookup, payload sizes, and detect exposed API keys without uploading files to any server.

How to Use HTTP Archive (HAR) Waterfall Analyzer
Export HAR from DevTools
Open Chrome/Firefox DevTools (F12) > Network Tab > Right-click any request > 'Save all as HAR with content'.
Inspect Waterfall & Latency
Explore the color-coded waterfall to isolate slow TTFB, uncompressed assets, or high connection handshakes.
Audit Credentials & Export cURL
Review automated security alerts for exposed tokens, cookies, or cleartext HTTP, and generate cURL commands.
Practical Examples & Conversions
500ms total request duration with 420ms waiting (TTFB)
Flags backend execution or database query bottleneck rather than network transfer latency
