We used Flynn over the last 12 months (tech agency, lots of fairly small projects) but gave it up in favour of Dokku. Every single one of our nodes eventually died, and we were unable to recover them. They chewed up disk space continuously and eventually ran out of disk and then were not recoverable. Other times they just died and would not restart all the required services. This was not even as part of a cluster; just single nodes. We raised issues and messaged on IRC but nothing happened. We really wanted to like it, but that was our experience. There's a lot of magic going on behind the scenes, which makes it really hard to even start to try and resuscitate a dead node. Sorry Flynn! We moved to Dokku and are really happy with it. It's not H/A but it's mega simple and it works really well. It's basically just Docker, buildpacks and the networking to wire everything together. The plugins also mean it's more useful than Flynn - if you need something like ElasticSearch you just install the plugin. Ditto LetsEncrypt etc etc.
