I essentially earned a college degree’s worth of languages/frameworks (Ruby, Node ecosystems) on free Heroku instances, and I owe my career to it. Other comments speak to this point as well. There’s probably a generation of us who completed some blog/O’Reilly “curriculum” involving Heroku > Digital Ocean > AWS > etc.<p>I never paid Heroku a dime and, after everything has shaken out, I don’t know why I would start now.
