1. Access process. With CZDS, you need to request access to each TLD separately, and in most cases wait for the registry to approve your request. AllZonefiles.io gives you instant access to the full dataset without having to file or wait for approvals.
2. Single unified format. CZDS provides raw zone files as text (BIND format), which require parsing and conversion if you just want a simple domain list. AllZonefiles.io delivers ready-to-use domain lists, already normalized and updated daily.
3. Simplicity and API access. With CZDS you have to download and manage dozens/hundreds of files individually from different registries. AllZonefiles.io consolidates everything into one place, with an option to download a single ZIP bundle containing all zones, plus APIs for automation.
4. ccTLD zones availability. CZDS does not provide them, while AllZonefiles.io provides ccTLD zonefiles (currently 78M domain names across 312 zones)
5. Daily new/expired domain lists. CZDS does not provide them (you have to download, keep at least 2 daily copies and calculate diffs yourself), while AllZonefiles.io has this ready to download for any date you want.
In short: CZDS is the official raw source for part of the zones, while AllZonefiles.io is a consolidated, instantly accessible, and developer-friendly service built on top of that ecosystem — designed for people who need clean, ready-to-use domain data without the overhead.
Good dataset if you can maintain freshness.
Are you using saaspegasus? The UI seems familiar.
No, this is not saaspegasus. Just a custom UI based on Bootstrap 5, no any boilerplate SaaS framework behind it.
How is this different from the ICANN site? https://czds.icann.org/home
Good question — thanks for asking!
