lucide icons and feather icons https://feathericons.com/ https://lucide.dev/

If you're on React, https://mui.com/material-ui/material-icons/

Check https://icomoon.io/

You can create your custom font with existing sets of icons and get a nice overview of existing freebees.

Though you will not get 53000 icons as fontawesome , you would get 1000 icons for free & lucide actually worked with svelte really nicely
