ColeSoft
ColeSoft produces the world’s most versatile suite of debugging tools for IBM mainframes.
Whether you’re modernizing legacy applications or supporting critical system level exits, Z/XDC brings clarity to the most complex code and makes the invisible visible.
ColeSoft software makes z/OS-based assembler, C/C++, Metal C and COBOL programs easier to work with and understand, improving time-to-market and code quality across the board.
Software bugs can extend development timelines, undermine user trust and lead to cost overruns. ColeSoft’s debugging tools are purpose-built for mainframe development, reducing time to resolution by up to 45%. Our dedicated solutions—whether for comprehensive application debugging, specialized C/C++ development, precise assembler analysis or our robust core engine—empower teams to resolve issues early and deliver reliable applications faster.
You can’t modernize what you don’t understand. We surface the usage patterns, dead code and hidden dependencies that determine your future architecture. The result? Successful modernization projects that don’t break the business.
We give developers deep, precise, real-time insight into how their applications behave—line by line, moment by moment. No more assumptions. No more black boxes. You see how it executes. You know where to fortify. Your business just got more resilient.
Z/XDC doesn’t replace your instincts. It supercharges them with truth, transparency, and control. Because great businesses deliver innovation. And innovation requires great tools.
