Introduction

Dqmainer is a domain information batch query tool based on RDAP / WHOIS protocols. Quickly obtain domain registration status, expiration dates, registrars, and other key information. Suitable for developers, domain investors, and SEO practitioners.

The Problem I Faced

Most domain providers send me emails a month before the domain expires, but a month passes quickly. If work gets busy and I forget about the domain, it could easily be snatched by someone else. So I thought of writing a tool to query domain information.

Initially, I mainly wanted to check the remaining expiration time. Later, I found that it wasn't displayed very clearly, so I added a days counter to make it easier for users to see when domains expire.

The domain information that can be queried isn't extensive, but it's sufficient for use. Additionally, I've opened up API queries, mainly for planned integration into mobile apps.

What It Can Do

• Domain Query - Get domain registration status, expiration dates, registrars, and more
• Batch Query - Query multiple domains at once to improve efficiency
• Domain Bookmarks - Bookmark domains, organize with custom groups, and batch-check status with one click
• API Support - Provide API interface for easy integration into other applications

Solutions Provided

Existing domain query websites don't support batch queries, and some require login. When holding multiple domains, querying one by one is time-consuming. Dqmainer provides a login-free batch query solution, avoiding missed renewals and domain snatching.

What You'll Get

A login-free tool for batch querying domain information. Enter multiple domains at once to view registration status, expiration dates, and registrars, with remaining days clearly displayed. Combined with bookmark grouping and API access, you can manage any number of domains in one place—never worry about forgetting to renew and losing your domains again.
