Bountysource is a website for open source bounties and since 2012 also for crowdfunding. Users (called backers) can pledge money for tasks using micropayment services that open source software developers can pick up and solve to earn the money. It also allows large-scale fundraising for big improvements on the project. It integrates with GitHub using its bug tracker to check if the problem is resolved and connect the resolution with GitHub’s pull-request system to identify the patch.
