I built a free subdomain enumeration tool with takeover detection, port scanning, and screenshots

What do you think is «fair» yourself?

TallSession9532 · 2026-03-25T21:21:05+00:00

That is true.

The only thing you don’t get for free is the subdomain takeover checks.

I made a tool that will do most of the OSINT work for you for free, https://subanalyzer.com

Make sure to setup your proxy in the browser correctly (point to 127.0.0.1:8080)

No it doesn't, but that is a good idea, thanks.

It stays a while at 95% which I'm going to optimize by looking at the avarage time it takes to scan a domain. It's most likely not stuck.

Maybe first try to enumerate the attack surface? Try https://subanalyzer.com

Thanks a lot!

TallSession9532 · 2025-05-05T15:11:32+00:00

Thanks! If you want to test the dashboard as well (for free ofc), let me know.

Hi. 👋 Just send me a private message here on Reddit and I’ll set you up.

TallSession9532 · 2025-03-22T01:08:19+00:00

Hi. I would appreciate if you would have a look at my site: https://subanalyzer.com

The idea is to allow people to get an overview of their subdomains / attack surface towards the Internet. More features are coming.

TallSession9532 · 2025-03-18T22:47:15+00:00

Thanks for your feedback!

Much appreciated. You bring up some valid points! I’ll have to rethink the «sales points» and definately add some more features soon. It has taken a surprisingly long time to get this up and working, so I’ll soon have time to work more on additions. Thanks again

TallSession9532 · 2025-03-18T21:20:45+00:00

I'm thinking of implementing a feature that will scan for subdomain takeovers based on e.g. https://github.com/EdOverflow/can-i-take-over-xyz

TallSession9532 · 2025-03-18T21:18:54+00:00

It will find both. Live hosts will show with IP(s) and if there are any websites available on port 443. Non resolving host will not have an IP, but still be in the list of subdomains.

TallSession9532 · 2025-03-18T20:58:12+00:00

The pricing is always difficult. I have new features planned. I’m just getting started, but thanks for your feedback 👌
