About this product

h5i is a Rust web framework built on Axum that brings formal verification with Lean 4 into everyday web development, alongside integrated red-teaming and CI/CD tools. It's designed for Rust developers and teams building AI-generated or security-critical applications. As AI makes coding faster, ensuring correctness becomes increasingly important. h5i helps developers prove critical properties and discover vulnerabilities that traditional testing alone might miss.
