Best FREE webhosting services

I don't know anything about this market. Can anyone make any good recommendation?

000webhost-

For starting a new project you have, this is not "host" but comes with free hosting (if you are looking for free hosting service without any CMS preinstalled, look for 000webhost).
wordpress.com
blogspot.com

And please don't come and say you see ads insered. That's how free hosting works. Limited or with ads insered.

Keep in mind, free hosting is limited with resources and is only for testing purpose.

If you are looking for serious business, blog or starting a new project, free hosting is a bad idea.

Also, is good to remember. In free Hosting you are the product, don't be scared if you start receiving spam emails and marketing emails from other things you never subscribed.
Never forget, free hosting never will clean your ass for free. You are the product, if they need money they will sell your data.

I've tried InfinityFree and 000webhost .
Both are great but you can't expect much from a free hosting. check them out based on your needs like free ssl, cpanel or not and ...
remember 000webhost can have some downtime which is normal

I will also suggest for 000webhost, else if you are planning for a quality hosting provider later go for a free trial(1-6 months ) which many of the hosting providers give.

Thank you
