Is Vessel worth the price?

Fair value

While the 'Free' tier offers a generous starting point with unlimited API calls and 5 development connections, the jump to custom pricing for more connections makes it hard to compare value.

This model is best for early-stage startups and developers needing to test integrations without immediate cost.
