I Built a Desktop COBOL Migration Tool That Converts to 6 Modern Languages

COBOL migration is the hottest topic in enterprise tech right now. Anthropic's Claude Code blog post knocked $40 billion off IBM's market cap in a single day. Banks are panicking about the "COBOL cliff" as 92% of COBOL developers approach retirement by 2030. I spent the last six months building a COBOL migration tool that takes a different approach from the AI-powered solutions making headlines. Easy COBOL Migrator is a desktop app that transpiles COBOL to C++ 17, Java 17, C# 12, Python 3, Rust and Go. It uses a full compiler pipeline, not an LLM. Everything runs offline. Your source code never leaves your machine. Why not use AI for COBOL migration? For a 200-line program, pasting COBOL into ChatGPT works fine. For a 200,000-line codebase with 300 shared copybooks and COMP-3 packed decimal arithmetic, AI-based COBOL migration breaks down for three reasons. The output is non-deterministic. Same COBOL in, different code out. Every time. Try reviewing or diffing that across a project wit
