PonyDebugger vs RenderDoc

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.

RenderDoc is a frame-capture graphics debugger for graphics development, released under the MIT license and available free. It supports Vulkan, D3D11, D3D12, OpenGL, and OpenGL ES, with HLSL, GLSL, and SPIR-V listed among supported languages. Its listed platforms are Windows, Linux, and Android; Nintendo Switch support is noted for authorized developers using NintendoSDK. The API support table marks OpenGL 1.0–2.0 compatibility as supported, while D3D9/10 and Metal are unavailable. Linux support is limited to 64-bit x86. Windows users can choose 32-bit or 64-bit builds or a portable ZIP, and the 64-bit build can capture 32-bit programs. Stable and nightly binary releases are available; stable builds are recommended for new users because nightlies may be less stable. Documentation is online for the latest stable version and included as a CHM file in builds, with introductory videos also linked. The project lists GitHub issues, email, IRC, and Discord for questions and problems. RenderDoc is intended for debugging programs users created; its public support channels do not allow discussion of capturing programs they did not create.
