There are many, many self-hosting analytics tools, from your own big data pipes to tools like the aforementioned piwik, as well as Open Web Analytics.   I like Snowplow (<a href="http:&#x2F;&#x2F;snowplowanalytics.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;snowplowanalytics.com&#x2F;</a>), but it&#x27;s currently hard-coded to AWS.<p>Hosting your own analytics data can be great, but there are lots of ways to get better accuracy and control over your data without having to host everything.   Still, if you can, it&#x27;s great.
