## Which is easier to build with?

Vapi is easier for teams that want a managed API and faster time to a live phone call. LiveKit is easier for teams with infrastructure experience who want open-source control. Vapi is a closed-source API with built-in phone-number provisioning and helper classes for telecom, according to [Modal](https://modal.com/blog/livekit-vs-vapi-article). LiveKit is open-source under Apache 2.0, supports Python and Node.js, and requires you to handle telephony integration yourself, according to [LiveKit's documentation](https://docs.livekit.io/agents/).

Vapi's documentation includes quickstart guides for inbound and outbound calls, with code examples that provision a phone number and start handling calls in under 50 lines of code, according to [Vapi's documentation](https://docs.vapi.ai/quickstart/introduction). LiveKit's Agents framework gives you more infrastructure control but requires more setup: you deploy the framework to your own infrastructure or LiveKit Cloud, integrate a SIP trunk for telephony, and handle call routing yourself, according to [LiveKit's documentation](https://docs.livekit.io/agents/).

Vapi is more telephone-focused with helper classes for telecom, according to [Modal](https://modal.com/blog/livekit-vs-vapi-article). LiveKit is better at infrastructure control and compliance economics; Vapi is faster to a live phone call, according to [Cekura.ai](https://www.cekura.ai/blogs/livekit-vs-vapi).

## Which handles telephony and call quality controls better?

Vapi is better at telephony for teams that want bundled phone numbers and managed call routing; LiveKit is better at call quality controls for teams that need video support and custom media pipelines. Vapi bundles phone-number provisioning, bring-your-own-carrier support and SIP trunking, according to [Vapi's homepage](https://vapi.ai/). LiveKit requires you to bring your own carrier and handle SIP integration yourself, but supports video calls and custom media pipelines, according to [LiveKit's documentation](https://docs.livekit.io/agents/).

Vapi's Build plan includes 10 concurrent lines, then $10 per line per month, and 14-day call history retention, according to [CloudTalk](https://www.cloudtalk.io/blog/vapi-ai-pricing/). LiveKit does not publish concurrent-line limits or call-history retention in the supplied sources. Vapi's documentation lists interruption and turn-taking controls, according to [Vapi's documentation](https://docs.vapi.ai/quickstart/introduction). LiveKit's documentation lists interruption and turn-taking controls, according to [LiveKit's documentation](https://docs.livekit.io/agents/).

Warm transfer is documented for Vapi, according to [Vapi's homepage](https://vapi.ai/). Warm transfer is not documented for LiveKit in the supplied sources.

## Which offers more model and voice choice?

Vapi integrates with OpenAI, Anthropic, ElevenLabs, Deepgram, Cartesia, AssemblyAI, PlayHT, Azure, Gemini, Groq and Perplexity, according to [Vapi's homepage](https://vapi.ai/). LiveKit supports realtime models including OpenAI GPT-Live, Gemini Live API, Azure OpenAI Realtime API, Amazon Nova Sonic and SpaceXAI Grok Voice Agent API, according to [LiveKit's documentation](https://docs.livekit.io/agents/models/realtime/).

Vapi supports 100+ languages for multilingual customer support, according to [Vapi's homepage](https://vapi.ai/). LiveKit's language support is not documented in the supplied sources. LiveKit's text-to-speech provider list is not documented in the supplied sources.

The choice depends on whether you prioritize voice provider flexibility (Vapi) or realtime language model flexibility (LiveKit). Both support function calling during calls, according to their respective documentation.

## Which integrates better with your CRM and tools?

Vapi is better at integrating with CRM and calendar tools out of the box; LiveKit requires custom integration work. Vapi integrates with Salesforce, HubSpot, Zendesk and Zapier, according to [Vapi's homepage](https://vapi.ai/). LiveKit's CRM and calendar integrations are not documented in the supplied sources.

Vapi's Zapier integration gives you access to 5,000+ apps without custom code, according to [Vapi's homepage](https://vapi.ai/). LiveKit's open-source framework lets you build custom integrations with any API, but you write the integration code yourself, according to [LiveKit's documentation](https://docs.livekit.io/agents/).

Vapi is the closer fit for teams that want to connect to Salesforce, HubSpot or Zendesk without writing integration code. LiveKit is the closer fit for teams that need custom integrations with internal tools or APIs that Vapi does not support.

## Which is stronger on security and compliance?

LiveKit has better compliance economics for teams that need SOC 2; Vapi is the only option for teams that need HIPAA compliance. Vapi HIPAA compliance costs $2,000 per month as an add-on on either Build or Scale plan, according to [CloudTalk](https://www.cloudtalk.io/blog/vapi-ai-pricing/). LiveKit bundles SOC 2 Type II at the $500 per month Scale tier, according to [Cekura.ai](https://www.cekura.ai/blogs/livekit-vs-vapi).

PCI DSS, ISO 27001 and GDPR compliance are not documented for either vendor in the supplied sources.

Compliance depends on how you deploy the product. Vapi's HIPAA add-on does not make your deployment compliant with HIPAA; you must configure call recording, consent and data handling to meet your legal obligations. LiveKit's SOC 2 certification does not make your deployment compliant with TCPA, recording-consent laws or HIPAA; compliance depends on how you configure the framework. Recommend legal review before deploying either platform in a regulated environment.

### Cost formula and illustrative scenario

The formula for monthly cost is:

**monthly cost ≈ calls × minutes per call × all-in rate + platform fees + numbers + add-ons**

An illustrative scenario with 10,000 calls per month, 3 minutes per call, Vapi's all-in rate and LiveKit's Build tier:

| Input | Vapi (illustrative assumption) | LiveKit (illustrative assumption) |
| --- | --- | --- |
| Calls per month | 10,000 | 10,000 |
| Minutes per call | 3 | 3 |
| Total minutes | 30,000 | 30,000 |
| Platform fee | $0.05/minute | $0.01/minute (after 1,000-minute quota) |
| All-in rate | $0.30/minute | $0.01/minute + provider costs (not specified) |
| Platform cost | $1,500 | $290 (29,000 overage minutes × $0.01) |
| Provider costs | Included | Not specified (bring your own) |
| Total | ~$9,000 | $290 + provider costs |

This scenario assumes Vapi's all-in rate includes speech-to-text, language model, text-to-speech and telephony, and LiveKit's $0.01 per minute covers only the platform, with provider costs added separately. The pricing page does not specify what Vapi's all-in rate includes, according to [CloudTalk](https://www.cloudtalk.io/blog/vapi-ai-reviews/). The pricing page does not specify what LiveKit's $0.01 per minute includes, according to [Fora Soft](https://www.forasoft.com/blog/article/livekit-vs-agora-cost-analysis).
