Agentic Index
Pipecat vs Vapi (2026)
Choose Vapi to rent a managed voice agent platform and choose Pipecat to build on an open source framework with a usage priced cloud behind it. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Vapi charges 5 cents a minute as a platform fee with model and telephony costs on top, which Vapi's own calculator puts at about 8 to 13 cents a minute all in at its default providers, while Pipecat is free open source with cloud pricing from 1 cent an agent minute plus your model costs. Teams with voice engineering capacity keep more margin on Pipecat; teams without it ship faster on Vapi.
