Open Source Initiative

This page provides resources and layout guidelines for using the OSI Certification Marks.

The Marks

You can find the 'Open Source' marks here, and the 'OSI Certified' marks here.

Here's a really cool button for your webpage:

HTML Usage

We insist and ask that you link to the images of your choice instead of saving it on your own server; this enables us to update the marks as their legal status evolves.

Please follow this example:

<a href="http://www.opensource.org/docs/definition.php"> <img src="http://www.opensource.org/trademarks/opensource/web/opensource-110x95.png" alt="Open Source (OSI) Logo" border="0" width="110" height="95"></a>

Please pay special attention to the height and width variables. They are included in the image name.

Print Color Guide

A Color Guide for printing the "Open Source" and "OSI Certified" marks can be found here.

Thank you.
