## What it is
A Rust-based dynamic DNS (DDNS) client that keeps Cloudflare DNS records in sync with a changing home IP address. It ships as a tiny static Docker image (~1.1 MB) with IPv4/IPv6 support, notifications, heartbeat monitoring, and cron scheduling.

## Use cases
- keep cloudflare dns updated with my home ip
- self-host services without a static ip
- dynamic dns updater for raspberry pi
- update ipv6 dns records automatically
- lightweight ddns docker container
- access home network via custom domain name

## When to avoid
- your DNS is hosted somewhere other than Cloudflare
- you need a GUI or a DDNS provider with built-in update endpoints
- you want a one-shot script rather than a long-running scheduled container

## Facets
- artifact type: cli-tool
- maturity: active
- function: networking, configuration-management, scheduling, developer-tools
- domain: networking, self-hosted, cloud-computing
- platform: self-hosted, rust, cli
