Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

Do I have to re-activate my DuckDNS subdomain regularly?

No. DuckDNS is a free service that does not require reactivation or forum posts to maintain its existence.

Can a DuckDNS outage affect my DNS record if my IP changes?

It can matter if your dynamic IP changes right before the outage; otherwise, an already registered IP record generally should not be affected.

What port-forwarding setup issues do users report with DuckDNS?

Users report struggling with DuckDNS and port forwarding when running multiple services on different devices, such as Home Assistant and Nextcloud.

Does the LinuxServer DuckDNS container receive application updates?

Yes. LinuxServer says its container releases include regular and timely application updates.
