Server for testing code online

Hi everyone,
Right now i am working on small project in meteor. Currently i am working locally. I am still a beginner
and wants to know, if there are any free server where i can test my project online. I think before moving to a paid server i should test my project on free server( if available ) until its still in production.

And what may be the options for paid server.

Google Compute Engine, there is a f-micro option: https://cloud.google.com/products/calculator/#id=6a28ab29-e855-48a2-a323-e85f283c7a53
You will have to install the server from scratch: OS (linux ubuntu), nginx, mongodb…
