## What it is
QuickChart is an open-source web service that renders chart images and QR codes from URLs or POST requests, using Chart.js configurations. It can be self-hosted or used via the hosted quickchart.io API, making charts embeddable in emails, SMS, PDFs, and other static contexts.

## Use cases
- embed charts in emails and newsletters
- generate chart images from a URL for chatbots and SMS
- render Chart.js configs as PNG images
- generate QR codes via API
- create charts from Google Sheets or Airtable data with no code
- self-host a chart image rendering API

## When to choose
- you need static chart images embeddable in email, PDFs, or chat
- you already know Chart.js and want to render configs as images
- you want a self-hostable chart image API with no vendor lock-in
- you need QR code generation via a simple URL

## When to avoid
- you need interactive, client-side charts in a web app
- you need real-time streaming data visualization
- you require heavy custom Chart.js plugins on v3/v4, which have limited support

- artifact type: service
