The best free and paid tools for visually modelling your software architecture
⚡ Tl;dr
- Software architecture tools can be categorized into three groups, modelling tools, diagrams as code and diagramming tools.
- Modelling tools are suited for long-term documentation as they store reusable objects and relationships in the model, which keeps all your diagrams up to date.
🚀 Let’s kick-off
Diagramming software architecture provides several benefits to how we communicate complexity. Clear system designs give engineering teams an enhanced understanding of the architecture and plan for future development whilst identifying potential issues.
Modelling tools work best for long-term system design docs. Reusable objects and relationships are stored in the model, which keeps all your diagrams up to date.
1️⃣ IcePanel
