Questions
Does UniFi DDNS run on Cloudflare's free plan?
Yes. UniFi DDNS runs on Cloudflare's free Workers plan, and so does Appflare.
What does UniFi DDNS create in my Cloudflare account?
Appflare creates a Worker for UniFi DDNS. It also uses a domain. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.
How do I update UniFi DDNS?
When the catalog has a new version, UniFi DDNS's page in Appflare says Update available. Select Update: Appflare takes a snapshot first, so you can roll back to the version before. You can also let Appflare update it automatically.
Is UniFi DDNS open source?
Yes, under MIT. An open-source license: you may use, change and share the app on its terms. Its source code is at github.com/willswire/unifi-ddns.
