Why build with Atlassian

Customize your Atlassian product to suit your needs, or integrate your product with ours


Out of the box, Atlassian products are powerful tools that keep your team in sync. But every company is different, and “one size fits all” isn’t going to cut it for your company. Need a specific feature? You can build it yourself with our APIs. We’ll give you the tools to help you.


If you also make a tool that helps teams be more productive, why not integrate with our tools? Our products are used by tens of thousands of teams around the world. Connect directly into our growing customer base and change the way their teams work.
