Open Source Projects

At Tapjoy, our scale presents a ton of interesting and hard engineering problems.  While we believe in applying the right technology to solve the problem, sometimes that technology doesn't exist yet or isn't suitable for our cost / performance needs.

We're big users of open-source software and are excited to share with the community some of the technologies we've built at Tapjoy to tackle these engineering problems.  These projects are all used in production and are under continual development.


Tapjoy’s job processing system, intended to work with Amazon’s SQS and provide the performance, stability and flexibility to use in places where you traditionally would reach for Resque / Sidekiq.

Chore is designed to be queue agnostic and provide configurable processing models.

Slugforge is the Tapjoy packaged deployment tool.  It’s used to produce, store, catalog, and install static deployable artifacts from a source code repository.  Since it deploys static packages, going back in time is just as reliably as rolling out new code.

Today, Slugforge is used to deploy to all of Tapjoy's environments, from single servers to 400+ nodes.

Dynamiq is an implementation of an at-least-once queue written in golang and run in a cluster on top of Riak 2.0.  It exposes a simple REST API for publishing to topics and directly enqueueing to queues, as well as receiving batches of messages at a time.  It’s designed to be a replacement for Amazon's SQS and SNS.

FakeRiak is an in-memory Ruby driver implementation of the Riak API designed to be used in test environments to remove the external dependency of a running Riak server.  This library makes it easier to achieve isolation, confidence, and high performance from your tests without the maintenance of stubs.
