Due to Heroku turning into a Kafkaesque nightmare, I’ve moved RubyFlow over to fly.io. This comes with some teething issues due to the antiquity of the code, but I think I’ve sorted most of it out now. Let me know if any problems. (The front page is a bit slower to load due to how I’ve got the database temporarily set up in a separate data centre 😬 but this will resolve itself in due course.)
