Why people self-host Dashy
Dashy is a flexible start page with many layout and widget options. It fits people who want a personal or household portal that can be customized heavily.
The tradeoff is that broad customization can turn into theme maintenance. Keep configuration in version control and test mobile layouts.
Deployment notes
Dashy is listed with support signals for linux, docker. Check the upstream documentation before exposing it to the internet, review authentication defaults, and keep backups outside the primary host.
