OpenOCD vs PonyDebugger

OpenOCD provides debugging, in-system programming, and boundary-scan testing for embedded target devices through a debug adapter. It communicates with targets over JTAG or Serial Wire Debug (SWD), and can run as a server for GDB clients. Users can also interact through Telnet or GDB; its Tcl interface is intended for machine interaction, and configuration files can contain commands using the documented Tcl scripting API. The target list includes ARM, MIPS, RISC-V, Xtensa, ARC, AVR32, and other architectures. Release 0.12.0 notes support for Espressif ESP32, ESP32-S2, ESP32-S3 cores, and Raspberry Pi Pico RP2040, along with Zephyr and a no-RTOS option. OpenOCD supports remote debugging and exception breakpoints. It is free and listed for Linux, macOS, Windows, and self-hosted setups. The project says it is packaged in popular operating-system repositories and provides access to source code; community binaries are marked unofficial. Host configuration may take extra steps: Linux usually needs a udev rule for adapter access, and Windows requires driver configuration for each peripheral.

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.
