As I’m writing this now, 67% of plugins are compatible with Python 3! There needs toīe a massive shoutout to everyone who worked to make this possible, from those who contributed to core Installs tended to be manual ones, or developers who needed to test against OctoPrint running on Python 3. There’s no point installing on Python 3, if you then can’t install any plugins!

However, at the time of writing, only 2.3% of all tracked installs are running on Python 3.

Since OctoPrint version 1.4.0, the codebase has supported installation on both Python 2 and Python 3Įnvironments, as a result of Python 2’s EOL status.
