Deploy Kroki in one click installation.
Unified diagram-as-code API that converts text descriptions into diagrams using 30+ supported libraries.
What you can build with Kroki
Kroki is a unified HTTP API for generating diagrams from textual descriptions. Instead of installing and maintaining separate tools for each diagram format, Kroki wraps over 30 diagram libraries — including PlantUML, GraphViz, Mermaid, D2, Structurizr, and Excalidraw — behind a single endpoint that returns SVG, PNG, or PDF output.
Self-hosting Kroki on your VPS removes any reliance on public rendering services, keeps sensitive architecture diagrams within your network, and lets you integrate diagram generation into documentation pipelines, wikis, and CI/CD workflows without rate limits or data leaving your infrastructure.
Key features of Kroki
30+ diagram libraries

Pipeline integration
Drop-in compatible with Asciidoctor, Confluence, GitLab, and any tool that supports the Kroki diagram block syntax.
No external calls
All rendering happens locally on your VPS — architecture and system diagrams never leave your infrastructure.
