Wing's debugger provides a powerful toolset for rapidly locating and fixing bugs in single-threaded or multi-threaded Python code. It supports breakpoints, stepping through code, inspecting and changing stack or module data, watch points, expression evaluation, and command shell style interaction with the paused debug process.

The debugger is built around a TCP/IP client/server design that supports launching your application not just from Wing itself but also externally, as with CGI scripts or code running in an embedded scripting facility within a larger application. Remote (host to host) debugging is also provided.

Because the debugger core is written in optimized C, debug overhead is relatively low; however, you should expect your programs to run about 50% slower within the debugger.
