Understrap is a free, open-source WordPress starter theme that combines the Bootstrap front-end framework with the Underscores (_s) starter theme. It provides developers with a solid foundation for building custom WordPress themes using Bootstrap's grid system, components, and responsive utilities.

Understrap is designed for developers who want to leverage Bootstrap's familiar CSS framework within a properly structured WordPress theme without starting from scratch. It includes support for the WordPress block editor (Gutenberg), WooCommerce, and popular page builders. The theme is actively maintained on GitHub and widely used by agencies and freelance developers as a boilerplate for client projects.

Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time.

Which websites are using Understrap?

webatla detects every site using Understrap and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the Understrap 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 Understrap?

webatla detects Understrap on 11K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Understrap?

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 Understrap?

Buy the technology dataset, then download the complete list of domains we detect using Understrap, re-exported every day.

What else is in the Understrap technology data?

Each row places Understrap next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.
