Thanks for pointing that out! Crazy! If you don't need the fancy click&play cloud experience you are so much better off with online.net or hetzner.de IMHO.
I know cheap VPS providers but if I could host a small webapp for free forever, that'd be nice!
AWS free tier is valid one year only. Bandwidth is typically easy to monitor (to stay within the 1GB/month), but disabling egress to specific regions sounds much trickier.
Actually, AWS have some Always Free tier that doesn't expire after 12 months as well (https://aws.amazon.com/free/), although it doesn't look like it includes a VPS of any kind.
