NostrO

Nostr Osint Tool 🔎 𓅦

NostrO is a tool designed for conducting Open Source Intelligence (OSINT) operations on Nostr.
NostrO facilitates operations such as retrieving relay or user infos, search on notes, and more.

Development

I welcome pull requests and contributions!
This tool is a CLI implemented with cobra and go-nostr library.
I suggest using VS Code for local development.
For debugging you can create a launch.json file similar to the following (change the command you want to test):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceFolder}/main.go",
            "args": ["relay", "--info", "bitcoinmaximalists.online"],
            "env": {},
            "showLog": true
        }
    ]
}

Content: I believe that one of the best ways to learn a technology is to experiment and build upon it. That's why I've started developing a tool for performing #osint operations on #Nostr on my #github.
