Changelog

2026-07

Zone mirroring — point a zone at an upstream zone (any provider, same team) and DNScheck keeps it in sync automatically: a full one-way mirror that's reconciled after every provider sync and after edits to the upstream, with drift repaired instead of just flagged. Mirrored changes are labeled in the zone's history so you can tell them apart from manual edits.
Zone health checks — every sync now runs a suite of checks per zone, shown in a Health panel on the zone and a status dot in the zones list: nameserver delegation, dangling CNAME/ALIAS targets (with subdomain-takeover fingerprinting), SPF, DMARC, DKIM, domain expiry, and registrar transfer lock. Failures alert through your notification channels; recoveries do too. See the health checks docs.
Checks page — a cross-zone list of every health check, searchable and filterable by status, check type, and zone.
Domain expiry & transfer-lock monitoring — DNScheck queries the domain registry (RDAP) and warns 30 days before your domain expires and when the registrar transfer lock is off. Registries that don't publish this data are detected and the checks are hidden instead of showing a permanent "unknown".
Final-IP monitoring — track the IP a CNAME/ALIAS ultimately resolves to and get an event when it silently changes; flapping (geo-distributed) targets are auto-detected and paused.
Restore deleted providers — deleting a provider is now recoverable: it moves to a "Recently deleted" section for 30 days, from which one click restores its zones, history, and checks. After 30 days it's permanently removed.
Command palette — press Cmd/Ctrl K anywhere to jump to a zone or page, or add a record.
Confirmation on destructive actions — deleting providers or records (including bulk delete) and leaving a team now ask for confirmation first.

2026-06

More DNS providers — connect Hetzner DNS, Vultr, and Linode, alongside Cloudflare, DigitalOcean, and AWS Route 53.
Nameserver delegation checks — DNScheck verifies your domain's live nameservers still point at its provider and alerts you (email, Telegram, or webhook) if the delegation breaks, with a banner on the zone.
Trial reminders — team members are emailed when the free trial is almost over: 3 days before it ends and on the final day.
Automatic email alerts — your account email is set up as a notification channel at signup, so alerts work out of the box.
Alerts link to the zone — change and delegation notifications now include a direct link to the affected zone (and a zoneUrl in webhook payloads).
Site favicons — each zone shows its website's favicon in the zones list and detail views.
Friendlier zone details — TTLs are shown in plain language (e.g. "1 hour", "5 minutes"), and each zone now displays its provider and nameservers.
AWS Route 53 support — connect Route 53 alongside Cloudflare and DigitalOcean. Provider-managed records (alias, policy, apex NS) are shown read-only.
Recently deleted records — deleted records land in a "Recently deleted" view (with search and filters) and can be restored to the provider in one click.
Records search — a global Records page to search and filter every record across all your zones, with type and zone filters.
Bulk edit — select records in a zone and bulk delete, set TTL, set content, or toggle Cloudflare proxying.
Per-field change history — record updates now show exactly which value, TTL, priority, or proxy flag changed.
Dashboard stats — monitored zones, total records, and changes in the last 30 days at a glance.
Passwordless auth — sign in with passkeys or a one-time email code.
