A diagram repository built for developers and teams who think in diagrams.
TritonChart is a web-based platform for creating, organizing, and sharing diagrams. It supports 5 diagram languages — Mermaid, PlantUML, D2, Graphviz, and Ditaa — with a live editor, folder organization, team collaboration, and a full REST API.
We believe diagrams should be as easy to manage as code. Store them, version them, share them, and access them programmatically — all in one place.
Mermaid, PlantUML, D2, Graphviz, and Ditaa — each with per-type starter templates and live rendering. Mermaid renders client-side; the others render via Kroki.
Each diagram stores its language so you can keep your toolchain consistent.
Your diagrams are plain text (Mermaid, PlantUML, D2, Graphviz, or Ditaa). Export them anytime as SVG, PNG, or raw code. TritonChart can run on your own infrastructure with SQLite for simplicity or PostgreSQL for scale. Your data stays yours.
