Desktop COBOL migration tool. Converts COBOL to C++, Java, C#, Python, Rust and Go using a full compiler pipeline: lexer, parser, AST, semantic analyzer and 6 code generators. Not AI-based. Same input always produces the same output. All processing runs locally. Source code never leaves your machine. Handles 36 statement types, 220+ keywords, COPY/REPLACE preprocessing, file I/O and SORT/MERGE. Migration reports flag what needs manual review. Free demo available. No registration.

Hi Product Hunt! I'm Norbert, a solo developer in London.

I built this because the COBOL migration market has a massive gap:

Free tools barely parse real-world code
Enterprise vendors charge six figures
AI tools produce different output every time you run them

Easy COBOL Migrator sits in the middle. $2,995 for a desktop app with a real compiler pipeline that converts COBOL to C++, Java, C#, Python, Rust and Go. Deterministic output. Runs entirely offline. Your source code never leaves your machine.

Why now? Anthropic's Claude Code blog post about COBOL just knocked $40B off IBM's market cap. Everyone is suddenly talking about COBOL migration. AI is great for understanding COBOL, but you need a deterministic compiler to convert it reliably across hundreds of files.

The free demo handles files up to 500 lines with C++ output. Download, drop in your COBOL, see what comes out.

Happy to answer any questions about COBOL parsing, the compiler architecture, or the migration market.
