SystemDraw

SystemDraw is a web-based tool for drawing software architecture and system design diagrams. It focuses on architecting and designing software solutions, with the site presenting it as a way to speed up system design diagrams and simplify software development.

The product’s described features include drag-and-drop nodes for components such as load balancers, caches, and API gateways. Those nodes can be configured with algorithms and policies, and each one has custom attributes specific to its type. SystemDraw also includes a traffic estimator: users enter estimated reads and writes, and it calculates output storage, bandwidth, and cache requirements. The page says the tool avoids generic shapes and is intended to help with precise planning and refining software architecture.

It is described for people who are designing software, including both professionals and those just starting out. The site says it provides tools and resources for architecting and designing software, with guidance aimed at building scalable systems and improving software design efficiency. Drawing is available without login, and the product is offered for free. The page also calls it the only product specially designed to draw software architecture diagrams.
