About the Czechia web market

Czechia is one of Central Europe's most digitally advanced economies, with internet penetration approaching 85% of the population. The country boasts a robust IT sector, with Prague serving as a leading European hub for software development, cybersecurity, and tech startups. Global companies including IBM, Red Hat, and Avast have significant operations in the country, and the local startup ecosystem has produced notable successes in cybersecurity and SaaS. High-speed fiber and mobile broadband networks cover the majority of the population, with ongoing investment in rural connectivity.

The .cz ccTLD, managed by CZ.NIC, is one of the most actively maintained and technically innovative domain registries in Europe. CZ.NIC has been a pioneer in DNSSEC adoption and open-source DNS software development, contributing tools widely used internationally. The registry operates the Turris router project, a widely deployed security-focused home router. Czech businesses show strong preference for .cz domains, and the registry maintains millions of active registrations. E-commerce, digital media, and cloud services sectors are particularly dynamic, driving consistent growth in domain registrations and hosted services.

Frequently asked questions

How many domains are hosted in Czechia?

1.3M domains are hosted on servers located in Czechia (geo-located by IP), refreshed daily, each with DNS, WHOIS, technologies and ranking.

Can I download the list of websites based in Czechia?

Yes, as structured JSONL. A free sample is available first.

What's included for each domain, and how fresh is it?

DNS, RDAP/WHOIS, technologies, IP & country, PageRank and Harmonic for every domain, re-exported daily.

Can I download just the Czechia domains, or the whole database?

Both. Each dataset is a single downloadable file, buy just the one you need. Or buy All data for the entire database: every dataset combined (identity, ranking, technologies, DNS and RDAP/WHOIS) for Czechia and the whole web, in one file. Daily fresh export.
