Moverve Limited, the company that operates Line9, grants you a Creative Commons Attribution 4.0 International (CC BY 4.0) licence over the Line9-rendered diagram images published under /mermaid/*. That is the clean render on each
example page — the image offered as the page's primary image, and the one the Copy image
button puts on the clipboard.
The full legal text of the licence is the CC BY 4.0 legal code. This page does not replace that text. It states what we are licensing, who is granting it, and how we ask you to attribute.
Credit “Line9” and link to https://line9.ai. That is the attribution we ask for.
If you reuse an image whose Line9 watermark is still visible and unaltered, we accept that as the credit — no separate credit line is needed.
“Line9” and the Line9 mark are trademarks of Moverve Limited. This grant covers the image; it grants no permission to use those trademarks except as required for reasonable and customary description of the origin of the image.
This grant does not cover:
- Diagrams people create and publish at
/d/*. Those belong to the people who made them. - The stock-Mermaid comparison rasters on the same
/mermaidpages. Those are renders of another project's output and are not ours to license.
The Mermaid source on those pages is not covered by this grant either. This page licences only the Line9-rendered images.
The Line9 service is operated by Moverve Limited, a company registered in England and Wales under company number 06004531.
