All of these tools are insanely expensive (from my own experience at companies that have used them). I understand it, since building your own pipeline to handle the kind of throughput analytics takes is expensive and time consuming. Business leaders want the visibility but don't want to redirect dev resources to build and maintain these creaky data pipelines. It is the perfect market of high-value and low tolerance for build (on the build or buy spectrum).
But I am not going to pay $1000/month as a bootstrap startup. What open source alternatives exist that can be run on basic hardware?
I've tried airbyte, sling, and dlt (besides building several tools from scratch)
My best bet for now will be dlt if you have dedicated DE team, but sling will get you a long way for moving data around your warehouse
Not to say you cant use both tho
