API and micro service

I have started the curriculum and it tells me to host my site on the server.
can you point me to free servers where I could host my site and build it freely

I have tried Heroku, but it says I have reached my maximum build.

Hello there,

There are many options. Out of the box, the curriculum provides a link to Replit, where you can host and edit your projects. Otherwise, there is also CodeSandbox, Glitch, and Netlify.

I am not sure why you would be getting that message with Heroku, unless you really do have so many projects hosted on it?
