Point myapp.subdy.io at any IP, get a wildcard certificate, and update it from your router, your CI — or by asking Claude. Live in 30 seconds.
no credit card for free tier · instant propagation on both nameservers
Pick any free label — myapp.subdy.io is yours the moment you hit create. Reserved and lookalike names are filtered for you.
Set A, AAAA, CNAME or TXT records. Propagation to both nameservers takes seconds, not hours — no caching roulette.
One toggle issues a wildcard cert via DNS-01. Renewal is automatic; your reverse proxy never notices anything.
Full control over your zone with the ergonomics of a side-project.
Per-name resolution graphs, straight from our nameservers.
DNS-01 without touching a nameserver yourself.
Your Fritz!Box, OpenWRT or Synology already speaks our protocol. Paste one URL, done.
Independent providers, local zone caches. Our control plane can die and your name keeps resolving.
Subdy ships an MCP connector. Add it once, then create names, move records and renew certificates in plain language — from any chat.

Trial converts to $5/mo on day 8 — we email you two days before, and cancelling takes two clicks.
A subdomain like myapp.subdy.io pointing at any IP you choose, with DNS records you control, optional wildcard TLS certificates and dyndns2-compatible IP updates.
Our nameservers pick changes up within a second. What visitors see also depends on resolver caches — records default to a 300s TTL.
Yes. Any router or client that speaks the dyndns2 protocol (Fritz!Box, OpenWRT, ddclient, Synology) works with your API token as the password.
After 7 days the card you added is charged $5/month. We email you 2 days before that. Cancelling takes one click in Billing and your subdomains stay live until the period ends.
