DevPeek

Local HTTP(S) packet capture app for Windows/macOS with MITM proxy, param transform, and visual mocking.

Desktopfreemiumglobal

DevPeek is a local HTTP(S) packet capture app for Windows and macOS that adds parameter transformation and visual mock editing on top of classic MITM proxy capabilities, aimed at the gap Charles or Fiddler leave when a captured field is still AES- or Base64-encoded. It's for mobile and web developers who want capture, decoding, and mocking in one app instead of juggling a proxy tool, scripts, and Postman.
