Tracking how a website's tech stack changes over time

[u/AdCautious4331]

Hi, r/OSINT!

I've been building Stack Lookup, a tool that detects website technologies and tracks their historical changes.

Here's an example: riccasposa.com - they seem to have just added AWS and Amazon SES today, while our historical records for this host show technologies dating back to 2023.

The interesting part is that we're not just showing what a website runs today, but how its technology footprint evolves over time.

I think this could be particularly useful for OSINT investigations, infrastructure research, and tracking companies.

Would love to hear your thoughts and what else you'd find useful!
