Hi @lproven,
nice! I'm using several #CGIs #RFC3875 for personal (scaled to n=1) web applications - be it (ephemeral) #QRCode https://qr.mro.name, #GeoHash https://mro.name/g/u28br conversion, a #nodb guestbook https://codeberg.org/jugendhacktlab.qdrei.info/gaestebuch, a personal #ActivityPub server @aSeppoToTry or the hacky video-office-hours reservation system https://mro.name/sprechstunde. Once there even was a #HaveIBeenPwnd proof of concept https://blog.mro.name/2022/08/pwned-diy.
They're #rootless deployments running on #shared #hosting (except qrcodes and HaveIBeenPwnd).
