what does this service offer over an established tool like Coolify? currently hosting most of my services on a cheap Hetzner VPS so i'm interested what Disco has to offer
Coolify and other self-hosting options such as Kamal are great. We're all in the same boat!
I'd say the main differences is that we 1) we offer a more streamlined CLI and UI rather than offering extensive app/installation options 2) have an api-key based system that lets team members collaborate without having to manage ssh access/keys.
Generally speaking, I'd say our approach and tooling/UX tends to be more functional/pragmatic (like Heroku) than one with every possible option.
https://devpu.sh/ is another alternative, it has a nice UI built with Hypermedia (HTMX).
I am building https://github.com/openrundev/openrun/. Main difference is that OpenRun has a declarative interface, no need for manual CLI commands or UI operations to manage apps. Another difference is that OpenRun is implemented as a proxy, it does not depend on Traefik/Nginx etc. This allows OpenRun to implement features like scaling down to zero, RBAC access control for app access, audit logs etc.
Downside with OpenRun is that is does not plan to support deploying pre-packaged apps, no Docker compose support. Streamlit/Gradio/FastHTML/Shiny/NiceGUI apps for teams are the target use case. Coolify has the best support and catalog of pre-packaged apps.
