Overview
Product summary
Review the store description, core capabilities, and common use cases.
This extension started as a small project: see the expiry date of a domain.
More functionality was added in time, and now the extension can show you everything about a domain name: WHO registered it, important dates (created or expiry), DNS Records, mentions in the news, WHOIS, RDAP, and more.
Highlights:
- Shows domain availability: registered, available or for sale
- Show at which registrar the domain is registered
- Important domain dates: registration date, expiry date

Most used extension by far Stay awesome team
Im an independent rookie security researcher here are my findings. Scope: Network activity & Software permissions Network activity: This software only makes network connections when explicitly opening the extension The software will always connect to the back-end API server owned by dmns.app (the developer). Im told this API server connects to other servers for whois data. The endpoints are stated in the documentation on the docs.dmns.app website. Depending on the domain you want to lookup the software may directly connect to third parties for more info about the domain. Domain connections: 1) domains-api.com (Back-end API) 2) i1.wp.com (Third party) 3) a.nei.cloudflare.com (Third party) 4) i.clarity.ms (Third party) 5) Google & Cloudflare DNS servers Permissions: - This extension can read and change your data on sites. This permission was automatic granted by Google Chrome. This permission can be revoked and is not required for the extension to function. Environment details: Extension version: 2.6.5 Chrome version: 147.0.7727.55 Host device: Ubuntu 24.04.4 LTS x86_64 Tools used: Portmaster, Wireshark Disclaimer: Due to the nature of my tools and experience the information provided may be inaccurate.
