Kickscraper is a library for interfacing with Kickstarter's undocumented/unannounced API. With it, you can get a lot of data about projects, whether you've backed them or not, including reward levels, amount pledged, links to the videos, updates, if it's been successful or not, and details about the creator.

I've begun to document all the types of data available on the Wiki for this project.


$ gem install kickscraper

Or for use in another app, add it to your Gemfile

# stay crazy up to date'
gem 'kickscraper', :git => 'git://github.com/markolson/kickscraper.git' 
# or use prebuilt gems that are probably pretty stable
gem 'kickscraper'


After several hours of quick hacking and copy-pasting, Kickscraper is able to authenticate against the Kickstarter API, store the returned oauth token and user object, fetch the user's backed projects, and view updates for those projects.

Left to do:

  • Gettings/caching for different endpoints
  • Error handling
  • Pagination support
  • Refactor to use object.urls.api values to construct gettings dynamically?
  • Testing!

Sample Usage

Provided with your user credentials this will list the first 20 or so projects you've backed, along with if the project is still active and if it has met it's funding goal.

require 'kickscraper'

Kickscraper.configure do |config|
    config.email = 'your-kickstarter-email-address@domain.com'
    config.password = 'This is not my real password. Seriously.'

client = Kickscraper.client
puts " A | C |"
puts "------------------------"
client.user.backed_projects.each {|x| 
    print (x.active? ? ' X |' : '   |')
    print (x.successful? ? ' X | ' : '   | ')
    puts x.name
