Sputnik is a website crawler written in Elixir.

It crawls a website following all internal links and makes a report of all pages’ status codes.

With query flags you can pass one ore more css selector to produce pages report about that.

Build

Usage

Sputnik takes the url to crawl and optional query to perform on the crawled pages:

Options

• query: valid css selectors, separated by commas, that you want to analyze all over the website
• connections: max number of concurrent HTTP connections (default is 10)

sputnik [--query <Q> --query <Q1> ...] [--connections <N>] <url>

Examples

running

./sputnik "http://spawnfest.github.io" --query "div" --query "a" --query "h1,h2,h3,h4,h5,h6" --connections 10

produces the following output
