https://www.gigalixir.com is a platform-as-a-service for Elixir apps. It only just launched a few months ago, but so far hasn't generated a profit. I spent 6 months building it and still hope it may take off as Elixir gains in popularity.
I had the idea to do the same thing dedicated to Django. I eventually stopped as I realized that I clearly underestimated the amount of work required to make it work better than Heroku.
Totally! The building and deploying is the easy part. Then you have to worry about configuration, secrets, versions, rollbacks, migrations, TLS, logging, load balancing, database hosting, backups, billing, maintenance, reliability, security, capacity, and usability, not to mention marketing and customer support.
Oh sorry about that. The free tier is obviously free, but once you need to scale up, you just pay for how much memory you need whether that's 1 big instance or many small instances.
