GTM Server started in 2020 as hosting for server-side tagging. We wanted to implement server-side tracking on our sites and our client’s sites and found no easy way to do that without clear documentation on how to set it up. We decided to build a tool that will simplify server-side tracking.
Since then, we have started building an infrastructure for server-side tracking. Created custom scripts, tags, plugins that help website owners and marketers to set up server-side tracking.
We also started a community, blog, and YouTube channel that will help to answer questions that our users have about server-side tracking.
