Piwik, Snowplow, etc. They do exist.<p>Then the question is do you really want to maintain the infrastructure required to run the analytics smoothly? Especially if your company has dozens of millions of pageviews a month and depends on the real time needs (extra infrastructure to support that).<p>Are you familiar enough with the stack so you could have a high degree of confidence that you can fix productions issues which are inevitable?

Again, often the answer here is &#x27;no&#x27;.<p>Of course, you have hosted solutions. But they are no better than GA in terms of privacy.<p>Paid support exists too but the cost can skyrocket pretty quickly, on top of paying for the infrastructure and maintaining it.
