All Debian releases are generally quite good for limited RAM circumstances. IME the main limit is the RAM used by `apt`, so for machines with less memory you may need to be patient during package upgrades, but unless you have very many packages installed (unlikely on small machines), 512MB should be plenty nowadays. [Meeting Minimum Hardware Requirements](https://www.debian.org/releases/bookworm/amd64/ch03s04.en.html) says 256MB should work as well. If the RAM requirements are too tight for Debian (e.g. 128MB might be impractical for Debian), OpenWRT may be a better option than an old Debian. Stefan
