I'm slowly moving off of NearlyFreeSpeech, but mostly because I'm going to my own self-hosting from a homelab (with what reliability downsides that will have), and I'm trying to retire my personal cloud bill.
For what it's worth, NFSN is the most excellent website host I've ever used, and I wouldn't hesitate to recommend it to anyone (technically adept) looking to spin up their own lightweight sites.
^ they are excellent. The philosophy, the principles, for which they are entirely unique among all providers. It's also entirely sustainable for many long term personal projects, you really can stick a tenner on your account and potentially forget it for years provided your site isn't stupid size (Although I only recently noticed at some point they stopped charging for per unit bandwidth). They've been around for a long time, and I hope they continue to be around for a lot longer. There is also something soothing about the no BS unchanging interface, not a single stock image in sight :)
I wish more services would use the prepay model that NFSN uses. For personal projects and even some minor business uses, I'd much rather have a site go down than be hit with a surprise bill because I misconfigured something.
