## What it is
Pintora is an extensible JavaScript text-to-diagrams library that renders diagrams from plain text, inspired by Mermaid.js and PlantUML. It works in both the browser (SVG/Canvas output) and Node.js (PNG/JPG/SVG output), and offers a plugin system for custom diagram types.

## Use cases
- generate diagrams from text in the browser
- render sequence diagrams from text in node.js
- create entity relationship diagrams as code
- draw gantt charts from plain text
- build mind maps from markdown-like text
- embed diagram-as-code rendering in documentation
- write custom diagram types with a plugin system

## When to choose
- you want a Mermaid-like diagram renderer that works in both browser and Node.js
- you need clean, self-contained SVG/Canvas/PNG output without global style pollution
- you want to extend the tool with your own custom diagram types via plugins

## When to avoid
- you need diagram types not supported by pintora and don't want to write a plugin
- you prefer a mature ecosystem with broad tooling integrations like Mermaid's
- you need a GUI-based diagram editor rather than text-driven diagrams

## Facets
- artifact type: library
- maturity: active
- function: templating, developer-tools, plugin-system
- domain: developer-tools, documentation, web-development
- platform: browser, cross-platform, cli
- tags: diagram-as-code, text-to-diagram, mermaid-alternative, plantuml-inspired, svg, sequence-diagram, er-diagram, gantt-chart, mindmap, nodejs
