PULSE Peek — macOS HTTP(S) proxy debugger (HTTP/2 + MITM)
A native SwiftUI app for capturing and understanding HTTP(S) traffic on macOS. No paywall: the app stays fully functional. Businesses buy a Business license for commercial use and compliance.
Commercial use requires Business. Unlicensed installs show an occasional reminder. Works offline.
