Why Rocq is better than Lean for program verification
Summary
This article argues Rocq is a better fit than Lean for program verification today, due to Rocq's native codata support, guarded coinduction, and direct extraction to runnable code. It compares language-level features, nested inductive types, and the extraction pipelines, and discusses ecosystem maturity, AI-agent hype, and regulatory considerations. The piece also provides concrete code examples and references to experiments and related projects.
