Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
design-is-code
Transform UML sequence diagrams and decision tables into Java tests and code. The DisC methodology applies London-school TDD to AI code generation: every design arrow becomes a verify test and every decision-table row becomes one leaf test, so mockist tests pin call structure, order, and arguments — leaving no room for AI interpretation. Phase 1 generates tests from the design; Phase 2 derives the implementation from the tests alone. Currently supports Java + Spring Boot with PlantUML sequence diagrams and Markdown decision tables.
AI Diagram Maker
Generate software diagrams from natural language, code, ASCII, images, Mermaid.
