DDD Sketch — Turn Domain Conversations into Architecture DDD Sketch is a free interactive tool that helps teams apply Domain-Driven Design (DDD) in a simple, guided and educational way. Instead of abstract theory or static diagrams, DDD Sketch walks your team through a practical modeling process — from business terms and domain events to clean architecture diagrams in C4 Model format (Context, Container, Component, and Code) using Mermaid.js. Whether you're a PM, Tech Lead, or Software Engineer, DDD Sketch helps you: 🧠 Understand the domain clearly 🧩 Identify Bounded Contexts 🔄 Translate discussions into real architectural artifacts 🎯 Align tech and business in a collaborative workflow No backend, no login — it's privacy-friendly and 100% in your control. You can even use AI (optional) to get contextual suggestions and avoid the blank canvas struggle. This is not just a diagram generator — it's a learning-first product designed by someone who struggled with DDD and wanted to teach it better. 👉 Try it now at dddsketch.com Built with ❤️ to make DDD accessible and collaborative for every team. #DDD #DomainDrivenDesign #MermaidJS #SoftwareArchitecture #ProductDesign #AI #OpenSource #DeveloperTools #DeveloperExperience #DevTools
