Is there any free tier in Google compute engine

update: Feb 2022

Yes, apart from 300$ credit for 90 days, there is an always free tier, that includes an App Engine, Compute Engine etc, more about free resources.

use their price calculator to get a cost estimate

Simple answer is YES

But it's not a 1 year trial like AWS.. it's a credit of $300 which expires in 60 days, after which you need to pay for continued usage.

Google provides Starter Pack, $500 credit package for new coming developers on Google Cloud Platform, $500 is more than 1 year free tier server on other platform.

Just apply it and watch that space :)

The correct answer is no, there is no free tier.
