draw.io trademark guidelines

draw.io is a registered trademark of draw.io Ltd (EU trademark 018062448). diagrams.net is a trademark of draw.io Ltd. The draw.io logo is also a trademark of draw.io Ltd.

These guidelines explain how you can refer to draw.io when you build a product that works with draw.io, write about draw.io, or distribute a modified version of the draw.io source code. They keep it clear to users which products are made by draw.io and which are not.

Refer to draw.io accurately​

You can use the draw.io name in text to state truthfully that your product works with draw.io. For example:

  • "Insert draw.io diagrams in your pages."
  • "Opens and saves .drawio files."
  • "Exports your network topology as a draw.io diagram."

Write the name as draw.io, in lower case, even at the start of a sentence.

Give your product its own name​

Don't use draw.io, drawio, draw-io, diagrams.net or a similar name as or in the name of your app, service, AI tool, MCP server, agent skill, website, domain, repository, package or social media account. A name such as "drawio-ai", "AI draw.io" or "draw.io Pro" suggests that draw.io makes your product.

Add-ons for other products: An add-on or plugin that puts the draw.io editor into another product can describe what it does, for example "draw.io integration for Acme Wiki". Give the add-on its own name where the host product allows it.

Don't suggest that draw.io endorses your product​

  • Don't say or suggest that your product is official, certified, endorsed or sponsored by draw.io.
  • Make it clear who makes your product. For example: "Acme Diagrams is not made or endorsed by draw.io Ltd. draw.io is a registered trademark of draw.io Ltd."
  • Don't use the draw.io logo, or a logo that looks like it, as or in the logo, app icon, favicon or social media profile picture of your product, project or business.
  • Don't change the draw.io logo.
  • Any other use of the draw.io logo needs our written permission.

Distribute a modified version of draw.io​

The draw.io source code is licensed under the Apache License 2.0. Section 6 of the licence does not give you permission to use the draw.io trademarks.
