Real-world cost comparison: what actually changes when you use templates and marketplace solutions instead of building Make vs Zapier workflows from scratch?

I’m evaluating whether templates and marketplace solutions actually deliver on the promise they make around faster deployment and lower total cost. Everyone talks about using ready-to-use templates to accelerate time-to-value, but I’m curious about what actually happens in practice.

Here’s what I’m trying to figure out: if I use a template designed for a Make vs Zapier comparison, does it actually let me run a realistic ROI analysis between the two platforms? Or do I end up customizing it so much that I might as well have built it from scratch?

And on the marketplace side—I know people sell automation templates there. Has anyone actually explored whether community solutions give you real cost savings when you’re trying to model competitive scenarios? Or is it mostly for simpler use cases?

I’m trying to understand if these tools actually reduce your time-to-deployment and cost-per-automation in a measurable way, or if the savings are mostly theoretical. What’s your actual experience with marketplace templates and their impact on your TCO?
