If you want free static hosting then probably: https://wasmer.io/

If you have the machine at home then you could set up port forwarding to it, but you would need to do everything yourself like:
- running a web server like nginx
- setting up ssl for it with certbot
- storing the static files in /var/www/html for example
- port forwarding from your router to that machine
- using some service like DuckDNS to point a domain to your dynamic IP at home
- pointing a CNAME to the DuckDNS subdomain on your domain
