Roundcube is a free, open-source webmail client that provides a browser-based interface for accessing IMAP email accounts. Written in PHP and JavaScript, it offers a rich user experience comparable to desktop email clients, featuring drag-and-drop message management, full MIME support, address book integration, and spell checking.
Roundcube is widely deployed by web hosting providers and ISPs as the default webmail interface for their customers. Its plugin architecture allows administrators to extend its functionality with additional features such as two-factor authentication, calendar integration, and custom themes. Roundcube is maintained by the Roundcube community and is one of the most popular self-hosted webmail solutions available.

RoundCube sites by TLD
The RoundCube dataset
Every site we've detected as running RoundCube, with version, hosting, country, TLD and traffic rank.
RoundCube lives inside 2 datasets
RoundCube detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 19,924-site list, or grab a free preview first.
Which websites are using RoundCube?
webatla detects every site using RoundCube and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.
Open the RoundCube technology dataset to break adoption down by country and TLD, compare it with a competing technology, and track new domains over time.
Frequently asked questions
How many websites use RoundCube?
webatla detects RoundCube on 20K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.
Can I download the list of websites using RoundCube?
Yes, as structured JSONL. Grab a free sample first.
What's included for each site, and how fresh is it?
Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.
How do I find the websites using RoundCube?
Buy the technology dataset, then download the complete list of domains we detect using RoundCube, re-exported every day.
What else is in the RoundCube technology data?
Each row places RoundCube next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.
Can I download just the sites using RoundCube, or the whole database?
