Does anyone still offer free hosting for Ruby on Rails apps?
Heroku and Fly.io both seem to be charging for there smallest plans (although I'm not confident in my understanding Fly.io's pricing tbh).
What about railway.app with their basic free tier? I had hosted couple of ruby on rails app but my free credits are almost over.
Render will host Rails apps, but if you can share more about what your app is, what other tech you need (Redis, PostgreSQL, uptime, etc) you can get more specific help.
