Kaizen 3C

Kaizen 3C is a software publisher focused on developer tooling for application modernization, with its catalog hosted at kaizen-3c.dev. The publisher's current range consists of a single product, Kaizen CLI, a command-line utility positioned in the architecture-driven modernization category of development tools. Kaizen CLI addresses a common challenge in enterprise software engineering: the difficulty of migrating legacy codebases to contemporary technology stacks without losing the architectural knowledge embedded in them. The tool follows a two-phase workflow. In the decomposition phase, it analyzes an existing legacy codebase and extracts its architectural intent into Architecture Decision Records, commonly known as ADRs, producing structured documentation that captures why the system was built the way it was. In the recomposition phase, that documented architectural understanding is used to guide the reconstruction of the application on modern frameworks, languages, or infrastructure. Typical use cases include organizations planning cloud migrations, teams replacing aging monoliths with modern services, and engineering groups that must modernize systems whose original authors are no longer available. By grounding modernization decisions in explicit ADRs rather than ad hoc interpretation of legacy source code, Kaizen CLI fits naturally into architecture documentation workflows, platform engineering initiatives, and incremental migration strategies. The command-line form factor makes the tool suitable for integration into existing developer environments, continuous integration pipelines, and scripted assessment processes. As the publisher's sole package, Kaizen CLI defines Kaizen 3C's specialization in the intersection of software architecture documentation and legacy transformation, serving development teams that want modernization efforts to be traceable, repeatable, and aligned with recorded architectural reasoning.
