Square open sources Kochiku

CircleCI (<a href="https://circleci.com" rel="nofollow">https:&#x2F;&#x2F;circleci.com</a>) offers this right now. We automatically partition your test suite and run it across multiple machines.<p>Except since it&#x27;s in the cloud, you don&#x27;t need to own 10 Mac minis to make this happen. And if you decide you want to split it 20 ways, not 10, you can do that in about 2 clicks.<p>[disclaimer: I work at <a href="https://circleci.com" rel="nofollow">https:&#x2F;&#x2F;circleci.com</a>, if that wasn&#x27;t already obvious]

I&#x27;m curious as to why Square would spend engineering talent on a distributed CI system when you can buy something like Jetbrains TeamCity that does what they wanted to do. This is not meant as a slam and I am also a developer who loves to build things but I would think Square and other companies for that matter would want to apply their limited engineering talents in solving bigger problems that grow the business.<p>Not looking for a flame war - just curious to get different perspectives.

One of the things i&#x27;m really loving about Square is the utilities that they are open sourcing that are not core to their business. I think this is great for the community.

When I was at Causes, we wrote a similar tool called Buffet (<a href="https://github.com/causes/buffet" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;causes&#x2F;buffet</a>, pronounced like the investor) for running test cases in parallel on an arbitrary number of machines; dropped out total build suite time from ~20 minutes on a single machine to 2-3 minutes. We certainly didn&#x27;t add the level of polish that Kochiku seems to have, though.

For distributed build, testing this is the best tool I&#x27;ve used: <a href="http://www.incredibuild.com/" rel="nofollow">http:&#x2F;&#x2F;www.incredibuild.com&#x2F;</a>. Unfortunately, it is not open source. Does anyone know of a free alternative to incredibuild with a similar feature set?

So now we&#x27;ve gone from adding an &#x27;er&#x27; to everything and dropping the &#x27;e&#x27; to using Japanese words and proper names for our products. And I was just going to iPost that to my iBlog.
