Neon's Launch and Scale plans include 10 and 25 branches respectively; every branch past that costs $1.50 per branch-month, prorated hourly, on top of compute and storage.
Xata charges no per-branch fee on its managed Cloud plan -- you pay only for the compute (from $0.012/hr) and storage ($0.28/GB-month) a branch actually consumes.
At fleet scale, compute rate is the bigger cost lever than the branch fee: Neon's Launch compute rate runs roughly 9x Xata's micro-instance rate, and that gap compounds across every branch created.
