Boto (using SES for email) is main one. And supervisord if you want to keep your deployment Python 3 only.

Still in progress, but there you go.

Circus is Python 3 compatible if people are looking for an alternative to supervisor.

There's always the option of just using Upstart or systemd as well.

Circus looks huge and doesn't appeal for one or two apps. I do however wish to experiment with circus at some point. Do you have any comparison to make, assuming you have used both? Or anyone out there? Thanks
