3who.com appears, based on the captured text, to be a lightweight tool for domain checking. The page includes entries such as “Check Domain,” “Single Domain,” “Multi Domain,” and “Export Excel,” indicating that its core purpose is to look up domain information, with support for both single-domain and bulk-domain processing. It also lists a creation date, update date, author, version number 4.0.11, support address, and source code address.
In terms of features and use cases, the tool has a fairly clear value proposition: helping users check domains and export the results to Excel, which makes it suitable for scenarios where domain lists need to be organized in bulk. For developers, webmasters, operations teams, or domain investors, multi-domain lookup and spreadsheet export can reduce the manual effort of copying query results.
As for supported languages or frameworks, the body text does not disclose the implementation stack, so it is not possible to determine which language or frontend/backend framework it is based on. Regarding open-source availability, the page provides a GitHub source link: https://github.com/viettools/checkdomain. This suggests that the source code is at least publicly accessible, though the specific license, contribution guidelines, and deployment instructions would still need to be verified in the repository. For self-hosting, the text does not clearly state whether one-click deployment, Docker, or server-based deployment is supported.
The captured content does not mention pricing, subscriptions, free quotas, or paid features, so the pricing model is unknown. There is also no information about an API or SDK, making it unclear whether the tool can be called programmatically. In terms of integrations and ecosystem, the only visible capability is Excel export; there is no information about integrations with CI/CD, domain registrars, monitoring systems, webhooks, or third-party developer platforms.
Its strengths are a focused feature set, what appears to be a low barrier to entry, and support for bulk lookup plus Excel export. The source code link is also useful for technical users who want to review or extend the tool. The drawbacks are that the public page provides very limited information: it lacks details on query fields, data sources, rate limits, accuracy, privacy handling, API access, deployment, and licensing. As a production-grade developer tool, it still feels under-documented.
Access from China cannot be determined from the text alone and should be treated as unknown. If access to the GitHub source code is unstable, that may affect users who want to inspect the code. Payment information is not disclosed. Alternatives include ICANN Lookup, Whois.com, DomainTools, as well as Chinese webmaster tools and domain lookup services from Alibaba Cloud and Tencent Cloud. Overall, it is better suited to lightweight, temporary, or bulk domain checking than to teams that require a full API, SLA, and enterprise-grade support.
