Reverse proxies (when self hosted) are totally free to use but you’ll still need to pay an annual fee to a domain registrar (like cloudflare for example) to register your domain (ex. Mysite.com or whatever) and then it’s as easy as creating subdomains for whatever internal services you want to expose to your friends (ex. Steam.mysite.com) so those folks with the link to your subdomain can access ONLY specific applications on your home server.

DM me, happy to walk you through it in detail if you need more help.
