This post might need a NSFW label.
Because I have added features which are so sexy !! 
OK, sorry, too arrogant, just very happy with the results.

I've just pushed a major update to the ClouDNS Steward app. It now includes a Script Builder that allows you to automate DNS management tasks directly from a Cloudron app.
New Features:
- Script Builder: Create automation workflows using a simple drag-and-drop interface. No coding required for standard tasks.
- Conditional "On Failure" Logic: Build self-fixing scripts. For example, run a dns-check (what is a dns record value) and automatically trigger a dns-set (add or update dns record) only if the check fails.
- Scheduling: Run your scripts automatically on a schedule (Hourly, Daily, Weekly, or custom Cron). No separate cron needed - it's in-app
- Domain Filtering: Target specific domains using tags (e.g., only run checks on domains tagged "prod" or "cloudron" )
- Extensible Actions: The system comes with core actions (like DNS checks and updates, and a Cloudron email config checker), but you can easily add your own custom Javascript actions into /app/data/actions/user/ to extend functionality. [some tech coding needed but core actions code provided and an in-app guide under Reference tab]
Because I choose to use CloudDNS which has to be Wildcard in Cloudron platform, I had to spend time in ClouDNS portal which is functional but quite manual.
I totally get that this app is 90% scratching my own itch, but hopefully can help others.
And maybe serve as a base for use on other DNS providers who provide an API (seems almost all).
Whether a modified version can have any usefulness for domains which are Cloudron-supported, I have no idea, because I have never used a Cloudron-supported DNS provider.
Happy to consider requests for other DNS providers.
I think the starting point is : do you have an itch that needs scratching ?
Roadmap :
- take the Script Builder to the next level where custom user actions can be built with a UI, rather than copy paste/edit code approach.
CloudDNS Steward is in the CCAI master catalogue for ease of deployment.
EDIT : the current approach for building user actions technically raises the prospect of the user screwing up their app container (but not their Cloudron instance). Seeking to resolve this through the next version of Script Builder with a better Action Builder to avoid this risk.
