Hey guys, do you have any idea where i can host a NodeJS application for free? It's a school project and id like to have it hosted somewhere to access it more easily.

Heroku will give you a free Dyno to test with, and they can host node apps. Might want to give that a shot.

I recommend Heroku for most purposes, but if you want a traditional VM with Linux, both Google and Amazon offer some free resources for some periods of time. Amazon offers a free year of t2.small I believe.

If you apply for the free github education pack. You get $50 to spend on digital ocean.
If you take the $5 p/m pack you have probably enough time.

Github education pack:

Digital ocean:

I have not found a truly free node host, only free trials.
Amazon AWS has a free trial that lasts several months. but as I recall you gotta set up a payment method and you will get charged for accidentally exceeding uptime or traffic limits.
Azure probably have something similar to Aws.
OpenShift used to have a free tier, but it's gone (they have a trial but only for a few weeks)

Cloud9 https://c9.io serves the purpose for me.
