My site costs me essentially nothing* to host (netlify and aws serverless technologies that are mostly under the free tier).
*My highest cost so far was when I was debugging serverless websockets and had a bug in my code that caused constant messages between the browser clients I was testing (which I left open for a day when I started work). That cost me $7 dollars.
I have my own service-hosted playground using little more than git and a few cli tools.
We need to rebuild the ad-free web.
