I didn’t have much expectations for free VPS hosting. After all, I have used free VPS such as Amazon, GCP, and Microsoft Azure before. In addition to the troublesome application process, the most important thing is that it also requires credit card verification. The AWS account I used before was charged because of the credit card. The account was suspended due to non-payment. However, a friend recently left a message saying that there are two free VPSs that are worth using.
