Kroki API
Development Tools
Kroki is a unified, open source diagram-as-code rendering service that provides a single REST API endpoint for generating diagrams from text-based definitions across more than 25 different diagramming languages and notations. Instead of integrating separate tools and libraries for each diagram type, developers use a single Kroki endpoint and specify the diagram type Kroki routes the rendering to the appropriate engine behind the scenes.

Different Kroki API use cases
- Nigerian Developer Documentation with Embedded Diagrams:Nigerian engineering teams writing technical documentation can use Kroki to embed live-rendered architecture and flow diagrams without needing diagram image files the documentation source contains the diagram definition as text and Kroki renders it on demand.
- Automated Report Diagram Generation for Nigerian Analysts:Nigerian data analysts and business intelligence teams can integrate Kroki into their reporting pipelines to automatically generate flowcharts and entity relationship diagrams from text definitions creating consistent, version-controlled diagram assets for reports.
- Nigerian Startup Architecture Documentation:Nigerian startups and development teams can use Kroki to maintain architecture diagrams as code storing PlantUML or Mermaid definitions in their git repositories and generating PNG or SVG renders for documentation and presentations.
