Dynamic DNS Updater

Dynamic DNS Updater is a simple app that updates a DNS record on a DNS provider. It has a simple web interface to configure the DNS record to update. It uses the Nuxt framework that is based on Vite, Vue3 and Nitro.

The Updater script can be run manually from the web interface or run periodically with api requests to /api/runscript.
