What We Offers
Support for the Engines You Love
PlantUML
A screenshot of PlantUML, which turns text code into visual maps. On the left is the typed-out code, and on the right is the actual deployment diagram it created, showing how a website’s internet traffic flows safely from the web address down into the servers and the main database.
A screenshot of Mermaid, which builds charts out of text code. On the left is the typed code, and on the right is the flowchart it made. It shows how user requests from a mobile app or website go through a security firewall, pass through a digital traffic controller, and get sent to different internal services like login or ordering systems.
A screenshot of Graphviz, which builds diagrams directly from text code. On the left is the typed code, and on the right is a corporate organization chart it generated, showing the company structure branching down from the Board of Directors and CEO to the technology and financial executives.
