## Bottom line

Vapi wins three of five use cases outright, with no wins for Deepgram Voice Agent API. For no-code agency deploys, Vapi's built-in no-code builder, white-label support, and native integrations with GHL, Zapier, Make, and Slack give agencies a ready platform Deepgram simply lacks. For outbound sales and SMB receptionist work, Vapi's $0.05/min base rate undercuts Deepgram's $0.075/min, and features like warm transfer, DTMF/IVR, a built-in knowledge base, and number provisioning reduce integration effort. The $50M Series B also signals deployment confidence. Deepgram's self-host option and $200 signup credit are notable, but neither swings a use-case win.

## Deepgram Voice Agent API vs Vapi: verdicts by use case

### No-code agency deploys → Vapi

For no-code agency deploys and white-label resale, the two most critical factors are a no-code agent builder and white-label sub-account support. Vapi offers a confirmed no-code agent builder and partial white-label capability for agencies, while Deepgram Voice Agent API publishes no such features. On production cost, Vapi's real range is $0.05-$0.17/min with LLM and TTS passed through at cost, giving agencies direct margin control. Deepgram's all-in rate is $0.075/min with no passthrough, meaning underlying model costs are bundled rather than transparent, which makes resale margin calculation harder. Vapi also carries a $0/mo platform fee, native outbound campaigns, and a rich native integration list including GHL, Zapier, Make, and Google Calendar. Deepgram is a strong API-first infrastructure play but is simply not positioned for no-code agency resale.

### Custom pipeline control → Tie

For engineering teams building custom pipelines, the ability to bring your own LLM and full API-first control are the deciding factors, and both Vapi and Deepgram Voice Agent API support both. Both also support bring-your-own TTS voice. Vapi adds a simulation/testing suite and native SIP trunking, which Deepgram does not publish details for. Deepgram offers self-host/on-prem deployment, which matters for teams needing full infrastructure control. Vapi publishes a 600 ms median end-to-end latency figure; Deepgram does not publish a comparable number. On pricing, Vapi starts at $0.05/min versus Deepgram at $0.075/min, though Deepgram offers $200 free credit upfront. The tools are genuinely balanced on the attributes that matter most here, with each holding a meaningful edge in different secondary areas.

### Healthcare compliance → Tie

For HIPAA-bound healthcare workflows, the single most critical requirement is a Business Associate Agreement. Vapi offers a BAA, but only as a paid add-on, not included on the base plan. Deepgram Voice Agent API has no published confirmation of a BAA at all. Neither tool clearly delivers an out-of-the-box BAA. On SOC 2 Type II, Vapi explicitly reports no certification, and Deepgram publishes nothing on this either. Vapi does have verified consent and recording compliance tooling and warm transfer to human, giving it some edge on supporting attributes. However, the two most decisive compliance requirements for healthcare remain unmet or unconfirmed by both platforms, making a clear winner impossible to name.

### Outbound sales campaigns → Vapi

Both platforms support native outbound campaigns, so that capability is a wash. On production cost, Vapi's real cost runs $0.05-0.17/min versus Deepgram Voice Agent API's flat $0.075/min, giving Vapi a cheaper floor for high-volume dialing. Vapi also includes 10 concurrent calls at the base tier with extra lines at $10/mo each, while Deepgram publishes no comparable concurrency detail. For call-center deployments, Vapi additionally supports native SIP trunking and warm transfer to human agents, rounding out a more complete outbound stack.

### SMB receptionist and booking → Vapi

For an SMB running a receptionist and booking service, keeping overhead low is the deciding factor. Vapi charges $0/mo platform fee versus Deepgram Voice Agent API's $0.075/min all-in rate, making Vapi far cheaper to run at low call volumes. Vapi also ships a built-in knowledge base, a no-code agent builder, warm transfer to human, and in-platform number provisioning, covering every core SMB workflow out of the box. Deepgram Voice Agent API does not publish equivalent no-code or knowledge-base capabilities. Vapi's richer feature set at zero monthly overhead is purpose-built for exactly this use case.

## Deepgram Voice Agent API vs Vapi: common questions

### Is Vapi cheaper than Deepgram Voice Agent API?

Vapi's listed base rate is $0.05/min versus Deepgram Voice Agent API's $0.075/min, so Vapi starts lower. However, Vapi's real production cost typically runs $0.05 to $0.17/min once LLM and TTS charges are added, since those are passed through separately. Deepgram bundles more into its rate but does not pass LLM and TTS costs through at cost. Which is cheaper depends on your model choices and call volume.

### Vapi vs Deepgram Voice Agent API: which is better for no-code agency deploys?

Vapi is the stronger fit for no-code agency deployments. It offers a built-in no-code agent builder, a knowledge base, warm transfer, DTMF/IVR support, and partial white-label and sub-account support for agencies. It also connects natively to tools like GoHighLevel, Zapier, Make, Slack, and Google Calendar. Deepgram Voice Agent API is API-first with no no-code builder, making it better suited for developer teams than agencies managing client accounts without code.

### Does Vapi or Deepgram Voice Agent API require an annual contract to get the best pricing?

Vapi requires an annual contract for its best pricing tier, while Deepgram Voice Agent API does not, offering pay-as-you-go access at standard rates. For buyers who value month-to-month flexibility, Deepgram Voice Agent API has a clear advantage.

### Is Vapi or Deepgram Voice Agent API better for HIPAA-compliant healthcare voice apps?

Vapi offers HIPAA BAA coverage as a paid add-on, not included in the base plan. No HIPAA-specific information is available for Deepgram Voice Agent API, though it does support self-hosting and on-premises deployment, which can aid compliance strategies. Healthcare buyers should verify BAA terms directly with both vendors.

### What free tier does Vapi offer compared to Deepgram Voice Agent API for developers getting started?

Vapi includes 60 or more free minutes for new users. Deepgram Voice Agent API provides $200 in free credit on signup under its pay-as-you-go plan. At Deepgram's base rate of $0.075/min, that credit covers roughly 2,600 minutes, making it a larger initial sandbox for heavy testing.

### Is Vapi or Deepgram Voice Agent API better for on-premises or self-hosted deployments?

Deepgram Voice Agent API explicitly supports self-hosting and on-premises deployment, while no equivalent option is confirmed for Vapi. Teams with strict data-residency or air-gapped infrastructure requirements should lean toward Deepgram Voice Agent API.

### How does Vapi handle LLM and TTS costs compared to Deepgram Voice Agent API?

Vapi passes LLM and TTS costs through to you at cost, meaning you pay those providers directly with no markup. Deepgram Voice Agent API does not use a passthrough model, bundling those costs differently. If you want transparent, at-cost AI spend, Vapi's approach gives clearer line-item visibility.

### What happens to my Vapi costs if I need more than 10 concurrent calls?

Vapi's base plan includes 10 concurrent calls. Each additional concurrent line costs $10 per month. Per-minute costs can range from $0.05 to $0.17 per minute depending on the AI components used, so high-concurrency, high-volume deployments should model both dimensions carefully.

### Does Vapi have SOC 2 Type II certification?

Vapi does not currently hold SOC 2 Type II certification. While Vapi does offer GDPR tooling and recording consent features, security-conscious enterprise buyers who require SOC 2 Type II attestation should note this gap and evaluate accordingly.

### Which native integrations does Vapi support out of the box?

Vapi natively integrates with GoHighLevel, Twilio, Telnyx, Slack, Google Calendar, Zapier, and Make. It also supports native SIP trunking and in-platform phone number provisioning, making it a strong fit for teams already using CRM or automation platforms in that ecosystem.
