I moved from Heroku to Render. Can't recommend them enough. Smaller operation, of course so keep that in mind if you need support, but for a hobbyist like myself, I'm running 2 postgres dbs, 1 redis instance, and 4 web services (2 websites).
(Render founder) thanks for the rec and feel free to get in touch with me anytime (email in profile). For those who need them, we offer enterprise support plans with response and uptime SLAs.
I just completed the move of my web app to render, and for now connecting back to Heroku for the postgres instance. I'll move that over eventually.
