DevPeek documentation

Hands-on guides in order: proxy setup, mobile SSL certificates and decrypt scope, capture with param transform, Map Route, and Mock, then mobile web debugging—mirroring phone browser pages on your desktop over the proxy.

• Quick startA guided first run: install, phone proxy setup, SSL certificate, first capture, and mobile web debugging.
• Install & preferencesWindows installer, language & theme, proxy port, auto-update and changelog entry points.
• Proxy & HTTPS / certificatesSystem proxy, SSL allowlists, and certs—trust the root CA before relying on HTTPS capture and debugging.
• Capture UI & requestsParam encrypt/decrypt, visual Mock, response search, details & resend; multi-client tabs and HTTPS decrypt.
• Param transformEncrypt/decrypt config and transform rules; Mock, Debug API, and details default to plaintext with auto encrypt on send.
• Map Route / ForwardMap production hosts to local or staging upstreams at the proxy layer—same rules for capture and mobile web debugging.
• Mock/BreakpointVisual manual & auto Mock, multiple enabled rules, request/response intercept and tamper.
• Mobile web debuggingProxy & SSL prerequisites, mirror phone web, DevPeek built-in debug panels & throttling; Chromium extension for PC.
• LAN collaborationDiscover peers, notes, send captures or debug recordings.
• FAQPlatform support, debug page won’t connect to phone, CSP vs preview, auto-update, and more.

Main UI at a glance

The main window title bar switches between Capture (param transform, Map Route, Mock, search, request details) and Debug (mirror mobile web over the proxy with DevPeek’s built-in debug panels). The title bar Rules menu opens encrypt/decrypt config, param transform rules, forward rules, and Mock settings; Proxy toggles recording, SSL, and Mock. Saved debug recordings live in History for export or LAN send; Record & replay is still maturing.

• Capture: tabs per client; decrypted params in details; visual Mock from the request list; search URL and optionally response bodies with regex.
• Debug: mobile HTML over the proxy—after proxy and SSL setup, mirror in DevPeek with built-in debug panels (not browser DevTools).
• Recordings & replay: export JSON from History or try timeline replay in a separate window (still evolving—not the primary workflow).

Decrypt HTTPS only where you are authorized—never use this on traffic you do not own or have permission to inspect.
