/ About /

Kroki is an open-source tool that provides a unified HTTP API for generating diagrams from textual descriptions, supporting over 20 diagram types including PlantUML, Mermaid, GraphViz, and more. Users can send diagram source code via GET or POST requests and receive rendered output in formats like SVG, PNG, PDF, and others. It is available as a free hosted service or as a self-managed instance on your own infrastructure.

/ How it works /

Users send diagram source code as text via HTTP GET or POST requests to the Kroki API, which renders and returns the diagram in the requested output format.

/ Who it's for /

Software developers and technical writers who need to generate diagrams programmatically
