I've heard of it; for me, messing with a system (even once) isn't really fun, it just gets in the way of spending time on my code. I don't have a ton of projects and Heroku has a free tier for things that don't need 100% uptime, so it's worth the extra couple bucks for me
Edit: I see DigitalOcean has it available as a 1-click install. Do you get totally automatic updates/system management and everything with that?
How do you keep things secure and up to date? That’s always been my problem and when developing an app I don’t want to do system administration so I always end up going with heroku (or it’s cheaper sibling render.com lately) because I don’t have time for system administration, backing up, etc.
I'm hosting 30+ apps (frontends / api's / cms's / other processes) on a single 5eu/mo DigitalOcean droplet. I believe Hertzner is the cheapest hosting provider with a 2,87eu/mo VPS.
Self-hosting is a lot of fun, and cheaper. Dokku has been around for several years, it's an open-source Heroku clone and I would recommend it to anyone looking into deploying web apps.
