What you can use it for

Generate chart images and QR codes on demand from Chart.js configs via web API.

  • Produces clean, watermark-free PNG and SVG chart images and QR codes via simple HTTP URLs.
  • Self-hostable open-source engine powered by Chart.js.
Workflow coverage and comparison notes

Generate watermark-free chart images (PNG, SVG) and QR codes from URL parameters or JSON payloads without Image-Charts paid subscription. Rate-limited free community tier or self-hosted AGPL.

Before you switch

Community has shared servers, variable latency and no SLA; its pricing lists AGPLv3 while the paid plan lists full commercial usage. Check licence obligations for business integration. Self-hosting incurs your own compute/hosting costs and does not remove AGPL obligations.
