# Vapi alternatives: AI voice agents compared

Updated September 2026

Vapi is a developer voice platform for teams that want full control of the stack. CallBolt's Sky is the handled-for-you option: one agent for calls, tickets and outbound campaigns, scoped and built with you.

TL;DR

Vapi fits engineering teams that want to choose every model in the stack, at $0.05 per minute plus $10 per concurrent line per month. With Sky, one agent covers the phone line, the tickets and the follow-up campaigns, in 26+ languages, with pricing scoped to how you use it. Pick Vapi for stack control; pick CallBolt to have the calls handled.

## Where is Vapi strong?

Vapi is built for engineers who want control: bring your own speech and language models, wire the orchestration yourself, and pay published rates of $0.05 per minute plus $10 per concurrent line per month.

## Who should pick Vapi, and who should pick CallBolt?

### Pick Vapi when

-   You want to choose and tune every model in the voice stack
-   You have engineers to own the agent as an ongoing build
-   Per-minute plus per-line pricing fits your model

### Pick CallBolt when

-   The phone line, the ticket queue and the follow-ups belong to one agent
-   You would rather describe the workflows than operate a stack
-   Callers switch languages mid-conversation and the agent should follow

If the phone line is the whole workload, the [AI answering service](https://www.callbolt.ai/ai-answering-service) page is the deeper read.

## What does CallBolt not do here?

If you want to own every layer of the voice stack and tune it yourself, Vapi gives you that control and CallBolt does not. Sky is for businesses that want the calls and tickets resolved, not a stack to operate.
