## How much do they cost?

_Pricing checked October 2026. Sources linked in each vendor section._

| Vendor | Pricing model | Published starting price | Included in the rate | Source |
| --- | --- | --- | --- | --- |
| LiveKit | Per-minute (Cloud) or self-hosted | $0.004/min ingress, $0.009/min egress (Cloud); free (self-hosted) | Media transport only (Cloud); provider costs separate | [LiveKit pricing](https://livekit.io/pricing) |
| Pipecat | Self-hosted | Free (self-hosted) | Framework only; provider and infrastructure costs separate | [Pipecat GitHub](https://github.com/pipecat-ai/pipecat) |
| Vapi | Per-minute platform fee + provider costs | $0.05/min + provider costs | Platform and telephony; provider costs separate | [Vapi pricing](https://vapi.ai/pricing) |

The formula for estimating monthly costs is:

**monthly cost ≈ calls × minutes per call × all-in rate + platform fees + phone numbers + provider costs**

Where the all-in rate includes the platform fee (if any), speech-to-text, language model, text-to-speech and telephony. For self-hosted frameworks, platform fees are zero but infrastructure costs (compute, storage) apply.

An illustrative example for 10,000 minutes per month:

_All inputs are illustrative assumptions for comparison only._

| Cost component | LiveKit Cloud | Pipecat (self-hosted) | Vapi |
| --- | --- | --- | --- |
| Platform fee | $90 (10,000 min × $0.009 egress) | $0 | $500 (10,000 min × $0.05) |
| Infrastructure | Included in platform fee | $200 (illustrative compute) | Included in platform fee |
| Speech-to-text | $50 (illustrative Deepgram) | $50 (illustrative Deepgram) | $50 (illustrative Deepgram) |
| Language model | $100 (illustrative OpenAI) | $100 (illustrative OpenAI) | $100 (illustrative OpenAI) |
| Text-to-speech | $150 (illustrative ElevenLabs) | $150 (illustrative ElevenLabs) | $150 (illustrative ElevenLabs) |
| Telephony | $100 (illustrative Twilio) | $100 (illustrative Twilio) | Included in platform fee |
| Phone numbers | $1 (1 number) | $1 (1 number) | $1 (1 number) |
| **Total** | **$491** | **$601** | **$801** |

At 10,000 minutes per month, LiveKit Cloud is the lowest cost, followed by self-hosted Pipecat, then Vapi. At higher volumes, self-hosted Pipecat or LiveKit would reportedly be cheaper than Vapi because the per-minute platform fee scales linearly, based on third-party sources. At lower volumes, Vapi's managed telephony may offset the higher platform fee by reducing engineering time.
