Bylazora Wants to Put COBOL Migration Through a Byte-Exact Gate

bylazora.com Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

An open-source migration engine that claims to move COBOL workloads to CPU, GPU, or cloud environments while checking outputs against the legacy system byte for byte.

Landing page captured for the 2026-09-15 issue.

Field notes

The site describes a single Rust binary that combines a migration validator, production runtime, and MCP server for coding-agent workflows. Its central constraint is byte-for-byte comparison with a legacy COBOL reference: agents may draft translations and run workloads, but only the validator can mark them proven. The homepage reports three identical backends in a per-account aggregation test at one billion rows, including a claimed 68.8× CUDA result. The supplied extract does not include the underlying proof artifacts.
