# Retell alternatives: AI voice agents compared

Updated September 2026

Retell is a developer platform for building voice agents, with per-minute pricing and a free credit to start. CallBolt's Sky is the handled-for-you option: one agent for calls, tickets and outbound campaigns, scoped and built with you.

TL;DR

Retell fits engineering teams that want to assemble their own voice agent, at $0.07 to $0.31 per minute with a $10 free credit. Sky is one agent across inbound calls, the ticket queue and outbound follow-ups, speaking 26+ languages, priced to your use case. Pick Retell to build it yourself; pick CallBolt to have it handled.

## Where is Retell strong?

Retell gives developers the pieces to build a custom voice agent: a template and documentation library, your choice of models, and published per-minute pricing ($0.07 to $0.31 per minute) with a $10 free credit to start.

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

### Pick Retell when

-   You have engineers who want to build and tune the agent themselves
-   You want per-minute pricing and a free credit to prototype with

If one agent for the phone and the queue is the shape you want, the [AI customer support agent](https://www.callbolt.ai/ai-customer-support-agent) page shows the flow step by step.

## What does CallBolt not do here?

Teams that want to assemble their own agent from models and parts will get there faster on a developer platform like Retell. CallBolt is the handled-for-you option: we scope and build the workflows with you instead of handing you a toolkit.

## Frequently asked questions

### Is CallBolt a good alternative to Retell?

Yes, when the goal is a working agent rather than a build project. Sky handles calls, tickets and outbound campaigns out of the box, while Retell gives developers the platform to construct their own voice agent.

### How does CallBolt's pricing compare to Retell's?

Retell publishes $0.07 to $0.31 per minute with a $10 free credit. CallBolt's plan is scoped to your use case with no per-seat fees, sized to your call and ticket volume, and quoted by the team within one business day.

### Does Retell handle support tickets?

Retell's pricing page covers voice minutes only; no ticket product is listed. On CallBolt, the phone call and the follow-up ticket are one agent's workload.

### Which is better for a non-technical team, Retell or CallBolt?

CallBolt. Retell is built for engineers who want to construct and tune the agent themselves; CallBolt scopes and builds the workflows with you, and the team answers within one business day.

### Can I prototype on Retell and move to CallBolt later?

You can, but they are different shapes: a self-built Retell agent and a scoped CallBolt deployment do not carry over. If the end state you want is production handled for you, starting with the team skips the detour.
