Welcome

🌟 Welcome to Sierra DevLink

Sierra Dev is your gateway to building powerful investigation tools and OSINT (Open Source Intelligence) scripts with ease.

🎯 What is Sierra Dev?Link

Think of Sierra Dev as a smart framework that helps you:

  1. Build investigation tools - Create scripts that gather, analyze, and visualize data
  2. Package and share - Distribute your tools like apps in an app store
  3. Use pre-built tools - Install 15+ ready-to-use OSINT tools instantly
  4. Automate workflows - Chain tools together for complex investigations

Real-World ExampleLink

Imagine you want to investigate a website. Instead of manually checking: - Who owns the domain - What technologies it uses - Its server location - Historical versions

You can run one command that does all of this automatically and presents results in a beautiful table!
