About Upstream

Open source is an amazing testament to human ingenuity.


We don’t often stop and take the time to celebrate what we—the creators and users of open source—have made together and the impact it has on our world.

So let’s stop and do exactly that!

On June 7, 2021, please join us for Upstream, a new one-day celebration of open source, the developers who use it, and the maintainers who create it. This 100% virtual, completely free event will bring together like-minded application developers, open source project maintainers, and the extended network of people who care most about their work.
