OllyDbg vs PonyDebugger

OllyDbg is a free 32-bit assembler-level debugger for Microsoft Windows, intended for binary analysis when source code is unavailable. It traces registers and identifies procedures, loops, API calls, switches, tables, constants, and strings. The debugger can load DLLs, attach to running programs, and handle multithreaded applications. Breakpoint types include conditional, logging, memory, and hardware breakpoints; execution tracing can log arguments for known functions. Patches can be retained between sessions, written back to executable files, and used to update fixups. An open architecture supports third-party plugins, and the maker provides a Plugin Development Kit with documented samples. Listed requirements include Windows 95, 98, NT 4.0, 2000, or higher; Win32s is unsupported. Development is frozen, and the 64-bit version is incomplete. Registration is free and requested for permanent or commercial use. The maker says original versions 1.00–1.10 do not communicate with other computers except for remote files specified by the user.

PonyDebugger is a free remote debugging toolset for native iOS apps. An app-side client connects to a gateway server, which presents debugging views through Chrome Developer Tools. Network traffic can be routed through a proxy for inspection in Chrome’s Network tools, including HTTPS; the client automatically proxies requests using NSURLConnection and NSURLSession. Developers can register managed object contexts and browse Core Data entities and objects, though these stores are read-only. The view hierarchy display can highlight matching views, edit displayed attributes, and remove nodes. Remote logging supports text and recursive inspection of object properties. Setup requires integrating the client and connecting it to the gateway; the quick start requires Xcode Command Line Tools. The gateway serves Chrome Developer Tools on localhost port 9000 by default, and can be configured for access from another device or computer. The iOS client requires iOS 5.0 or above. The project is Apache License 2.0; its README warns that automatic forwarding of all network traffic swizzles private API methods and should be limited to debug builds.
