It's pay as you go. So you can just pay for what you use.

Most apps only use a few cents a day if you're not doing something big.

Very cheap to extend it.

yes, but my project's trial is going to end after 5 days. but i need this project for 7 days. so i need just extend trial/subscription for 2 days, but not for month

so i dont want to pay 5 dollars for 1 month subscription, because I will not use it for more than 1 week

I don't think you're understanding. It's not $5/mo. It's pay-as-you-go, so if I run a server for 1 day, it costs me like $0.10. Some of my servers are $2/mo and some are $7/mo.

Don't complain too much or they'll shut down free plans (inevitable). It's a fantastic tool, far better than the others I've tried.

Hey, sorry Railway's hobby plan costs $5 monthly + additional usage beyond the included $5. Railway does not have a weekly plan.
