About .cz
The Czech Republic's country code top-level domain, .cz, is one of the most active ccTLDs in Central Europe. Administered by CZ.NIC, a well-regarded and technologically advanced registry, .cz serves the Czech Republic's approximately 10.9 million residents along with Czech businesses, government institutions, and diaspora communities worldwide. The Czech internet sector is highly developed, and .cz is the dominant domain extension for online activity in the country.
Delegated in 1993 following the dissolution of Czechoslovakia, .cz has grown to host millions of registered domains. CZ.NIC is recognized internationally for its technical contributions to internet security, including its work on DNSSEC and CSIRT (cybersecurity incident response). Registration of .cz domains is open to anyone globally without residency requirements, which has contributed to steady international adoption alongside its core Czech user base.

The .cz dataset
Everything we have on 1,174,683 active .cz domains in one downloadable file — fresh export every day.
Buy a dataset to download .cz
The full .cz slice (5.1 MB JSONL, fresh daily exports) lives inside each dataset. Get one from €29 to €599 per month and download immediately.
How to download the .cz domain list
The complete .cz domain list is available as one structured file. Every entry in the list is a single registered domain exported with its full record, so you can work it all offline instead of crawling it yourself.
Pick the dataset that fits your use case, then download the .cz list in JSONL (zstd-compressed) — the very same list that powers our API. A free sample of the list is available before you pay, and you can re-download the latest export any time during your access month.
Each .cz list includes, for every domain:
- DNS, RDAP and WHOIS records — registrar and dates across the full list.
- Detected technologies for each site in the list.
- Hosting IP, country and PageRank / Harmonic ranking.
- A daily-refreshed export, so the list you receive is never stale.
