Anyone know any good hosting options for little personal, experimental Rails apps that might not go anywhere (i.e. that I might well lose interest in but forget to cancel)?

I’ve always liked Vercel’s approach for these kind of side-projects, as I don’t have to worry about cancelling anything if I stop using it. But I guess that is a perk of it being serverless, which precludes Rails. What’s the next best option, something suitable for small, database-driven Rails apps?
