we've been loyal heroku customers for over a decade. should have switched off long ago, but as a small team, it was too valuable. such a shame.
It supports all the quality of life features like opening a shell via a cli, which I found was one of my favorite parts of Heroku (canine run —myproject /bin/bash)
Been fortunate enough to get a sponsorship from the Portainer folks, which allows me to maintain and develop full time!
Although I would consider, _when possible_, using Vercel or Netlify.
Of course you can do both with both of these services.
