DNScheck

DNScheck connects to your DNS providers, syncs every zone, and keeps a history of every record change. When something changes, or a health check fails, you hear about it by email, Telegram or webhook straight away.

Works with Cloudflare, AWS Route 53, DigitalOcean, Hetzner, Vultr and Linode.
