If a cloud company start providing a free tier even with limited resources they might go bankrupt within a few days 😂 unless they make the application sleep after a few hours just like Heroku.
There is already a website which provides a free plan to host your WordPress website for free with limited resources.
As far DigitalOcean is concerned, they might launch a special free tier plan for developers (by doing some verification process), because developers are awesome 😎.
I always wanted to host the Ghost blog for free 😋, if I could do that in a free plan, that would be great.
