Xcrawl3R – A CLI Utility To Recursively Crawl Webpages

xcrawl3r is a command-line interface (CLI) utility to recursively crawl webpages i.e systematically browse webpages’ URLs and follow links to discover linked webpages’ URLs.

Features

• Recursively crawls webpages for URLs.
• Parses URLs from files (.js, .json, .xml, .csv, .txt & .map).
• Parses URLs from robots.txt.
• Parses URLs from sitemaps.
• Renders pages (including Single Page Applications such as Angular and React).
• Cross-Platform (Windows, Linux & macOS)

Installation

Install release binaries (Without Go Installed)

Visit the releases page and find the appropriate archive for your operating system and architecture. Download the archive from your browser or copy its URL and retrieve it with wget or curl:

• …with wget:

   wget https://github.com/hueristiq/xcrawl3r/releases/download/v<version>/xcrawl3r-<version>-linux-amd64.tar.gz

• …or, with curl:

   curl -OL https://github.com/hueristiq/xcrawl3r/releases/download/v<version>/xcrawl3r-<version>-linux-amd64.tar.gz

…then, extract the binary:

tar xf xcrawl3r-<version>-linux-amd64.tar.gz

TIP: The above steps, download and extract, can be combined into a single step with this onliner

curl -sL https://github.com/hueristiq/xcrawl3r/releases/download/v<version>/xcrawl3r-<version>-linux-amd64.tar.gz | tar -xzv

NOTE: On Windows systems, you should be able to double-click the zip archive to extract the xcrawl3r executable.

…move the xcrawl3r binary to somewhere in your PATH. For example, on GNU/Linux and OS X systems:

sudo mv xcrawl3r /usr/local/bin/

NOTE: Windows users can follow How to: Add Tool Locations to the PATH Environment Variable in order to add xcrawl3r to their PATH.

Install source (With Go Installed)

Before you install from source, you need to make sure that Go is installed on your system. You can install Go by following the official instructions for your operating system. For this, we will assume that Go is already installed.

go install ...

go install -v github.com/hueristiq/xcrawl3r/cmd/xcrawl3r@latest

go build ... the development Version

• Clone the repository

   git clone https://github.com/hueristiq/xcrawl3r.git 

• Build the utility

   cd xcrawl3r/cmd/xcrawl3r && \
   go build .

• Move the xcrawl3r binary to somewhere in your PATH. For example, on GNU/Linux and OS X systems:

   sudo mv xcrawl3r /usr/local/bin/

  NOTE: Windows users can follow How to: Add Tool Locations to the PATH Environment Variable in order to add xcrawl3r to their PATH.

NOTE: While the development version is a good way to take a peek at xcrawl3r‘s latest features before they get released, be aware that it may have bugs. Officially released versions will generally be more stable.

  -d, --domain string               domain to match URLs
      --include-subdomains bool     match subdomains' URLs
  -s, --seeds string                seed URLs file (use `-` to get from stdin)
  -u, --url string                  URL to crawl

CONFIGURATION:
      --depth int                   maximum depth to crawl (default 3)
                                       TIP: set it to `0` for infinite recursion
      --headless bool               If true the browser will be displayed while crawling.
  -H, --headers string[]            custom header to include in requests
                                       e.g. -H 'Referer: http://example.com/'
                                       TIP: use multiple flag to set multiple headers
      --proxy string[]              Proxy URL (e.g: http://127.0.0.1:8080)
                                       TIP: use multiple flag to set multiple proxies
