A huge list of free stuff for webmasters

From the list, personally I've been using oracle to host a few vps, and improvmx to relay emails for my domain email. My private adguardhome dns server just costed a few $ for the domain name. Can be totally free if I opted to get domain name from freenom but I've figured free domain name is bound to be lost eventually so might aswell pay a few $. Ssl certificate i've got from letsencrypt. Theres also zerossl. Both arent mentioned in the list. Its shocking what one could get for free nowadays.
