Even though Steem is just a few month old, its developer ecosystem seems to be growing at a healthy rate.

At least 25 developers have been working on Steem-related projects during the last 30 days. There are four core Steem developers committing to the the main blockchain client repo and 6 contributors to the steemit.com frontend SPA repo.

There are client libraries for popular languages: JS (a few of them), Python, Go, PHP and Elixir. Many are still unstable, though, and are under active development.

This list of developers, open source repos and projects is limited. If you a developer on Steem or working on a Steem-related project, please get in touch and I'll add you to the list.
