we are thinking of moving away from Google Tag Manager. The focus on Google regarding GDPR and privacy issues are one reason. Also GTM is blocked by so many privacy blockers, that some of the benefits of running our own Snowplow pipeline are mitigated.
In an ideal world, integrating Snowplow natively would be the preferred option. However we are a very small team and this would probably create way to much overhead and also would slowing down our development process quite a bit.
What are the options out there? What tag management systems are you using? Preferably it would be an open source alternative, but the market seems to be very limited.
Some things that are in my bookmarks list:
https://getanalytics.io/ (Not sure if it replaces a tag manager)
https://iterative.ly/ (Not sure if it replaces a tag manager)
https://matomo.org/free-tag-manager/ (I’m not sure if this can be used without Matomo?)
