A subdomain finder is a tool used to find the subdomains of a given domain. Subdomains are created when a second-level domain is added to a top-level domain. For example, the subdomain "www" is a subdomain of the domain "example.com".

If you don't want to deal with servers and complex configurations when performing recon but would like more features in an integrated solution, Findomain offers a subdomains monitoring service that provides directory fuzzing, port scanning, vulnerability discovery, and more. Monitor your target domains with several popular tools (including OWASP Amass, Sublist3r, Assetfinder and Subfinder) and receive alerts through Discord, Slack, Telegram, Email, or Push Notifications (Android/iOS/Smart Watch/Desktop) when new subdomains are found.
The only thing you need to do is configure a file with your email address, webhooks, or Telegram information, and include your domains in another file. You will then have a fully-automated subdomain monitoring service that will keep you up to date with any new subdomains discovered, along with Host IPs, HTTP status, website screenshots, Open Ports, CNAME records, and more. User data is securely stored in a relational database -- you can request a dump of your data at any time.
When you finish your payment, you will receive an email with the server credentials and documentation regarding configuration and other details.
Note: Our private version is superior to the public version. By purchasing our private version, you keep this project alive and allow us to continue improving it.
The complete solution for domain recognition. Supports screenshotting, port scanning, importing data from other tools, subdomain monitoring, and more. Be alerted on your findings through services such as Discord, Slack, and Telegram. Multiple API Keys for sources and much more.
The following table demonstrates features that are available in the premium version (but not the free version) of Findomain. It aims to gives you an idea of why you should use Findomain and what it can do for you. The domain used for the test was aol.com. The details of the BlackArch virtual machine used in the test are outlined below:
The tool used to calculate the time was Linux's time command.
•Subdomains monitoring: put data to Discord, Slack or Telegram webhooks. See Subdomains Monitoring for more information.
•Multi-thread support for API querying, it makes that the maximun time that Findomain will take to search subdomains for any target is 15 seconds (in case of API's timeout).
•Parallel support for subdomains resolution, in good network conditions can resolv about 3.5k of subdomains per minute.
•DNS over TLS support.
•Specific IPv4 or IPv6 query support.
•Discover subdomains without brute-force, it tool uses Certificate Transparency Logs and APIs.
See Subdomains Enumeration: what is, how to do it, monitoring automation using webhooks and centralizing your findings for a detailed guide, including real-world examples, of how to get the most out of the tool.
Findomain uses Certificate Transparency logs and well-tested APIs to find subdomains. This method makes the tool much faster and more reliable than alternatives. If you want to know more about Certificate Transparency logs, read https://www.certificate-transparency.org/
Findomain makes use of multiple publicly-available APIs to perform the search. The following is a list of APIs that we are using at the moment:
•Certspotter
•Crt.sh Database (favorite) or Crt.sh HTTP API
•Virustotal
•Sublist3r
We offer ready-to-use binaries for the following platforms (64-bit only):
•Linux
•Windows
•MacOS
•Aarch64 (Raspberry Pi)
•NixOS

A Subdomain Finder is a subdomain enumeration tool that helps you discover subdomain hosts (aka subdomain FQDNs) which serve specific functions for your target (e.g. hosting public websites, private subdomains for testing web apps, URLs where you can find backups, etc.).
Optimize your website's SEO with our Subdomain Finder Tool, perfect for auditing, competitor analysis, and compliance.
A Subdomain Finder is a tool that discovers and lists all subdomains associated with a primary domain. In addition to subdomains URLs, the tool provides general data on each one, including traffic forecasts, traffic share, the number of keywords, and more.
Sep 11, 2024 · A subdomain finder can help uncover hidden web pages, test for vulnerabilities, and improve website performance. It is used by cybersecurity professionals, digital marketers, and website administrators. Geekflare has researched and compiled the best domain finders based on ease of use, domain scoring, and comprehensive scanning capabilities.
Scan and discover subdomains of a domain, including IP addresses and server information.
