Vapi is a developer platform for building voice agents that handle inbound and outbound phone calls. Teams build agents by writing code in TypeScript or Python using Vapi's SDKs and API, defining conversation flows, connecting language models and voices, and integrating tools such as CRMs and calendars through function calling, according to [its documentation](https://docs.vapi.ai/). Vapi handles the telephony infrastructure, speech-to-text transcription, language model orchestration and text-to-speech synthesis, allowing developers to focus on agent logic and integrations. Vapi is built for engineering teams at startups, agencies and mid-sized businesses that want programmatic control over voice agent behavior. Typical use cases include customer support lines, appointment scheduling, lead qualification, order status inquiries and outbound sales calls, according to [its use case documentation](https://docs.vapi.ai/use-cases). Teams launch agents by deploying code to their own infrastructure or serverless functions, then routing calls through Vapi's telephony layer. Vapi supports both inbound calls (where a customer dials a provisioned phone number) and outbound calls (where the agent dials a list of numbers), according to [its telephony documentation](https://docs.vapi.ai/telephony). The platform provisions phone numbers in over 60 countries or allows teams to bring their own SIP trunk. Vapi does not offer a visual builder or a managed service where the vendor builds the agent; all configuration is code-based. ## What are Vapi's key features? ### Conversation building and flow control Vapi allows developers to define conversation flows using code, specifying prompts, expected user inputs, conditional branching and error handling, according to [its conversation documentation](https://docs.vapi.ai/conversations). Developers write agent behavior in TypeScript or Python, using Vapi's SDK to structure the conversation graph. The platform supports dynamic prompt injection, allowing agents to pull context from databases or APIs mid-call. Vapi also offers interruption handling, where the agent can pause or resume based on user speech, and silence detection to prompt users who stop speaking. ### Telephony and call handling Vapi provisions phone numbers in over 60 countries and handles call routing, recording and transcription, according to [its telephony documentation](https://docs.vapi.ai/telephony). Teams can use Vapi-provisioned numbers or bring their own SIP trunk for enterprise deployments. The platform supports inbound calls (where users dial the agent) and outbound calls (where the agent dials a list of numbers from a CSV or API). Call recordings and transcripts are stored in Vapi's dashboard or exported via webhook. Vapi also supports call transfer to a human agent using SIP REFER or a third-party contact center, according to [its transfer documentation](https://docs.vapi.ai/transfer). ### Model and voice options Vapi integrates with OpenAI, Anthropic, Google and Azure language models, allowing developers to choose the model that fits their latency, cost and accuracy needs, according to [its model documentation](https://docs.vapi.ai/models). The platform supports streaming responses, where the agent begins speaking before the full model output is generated, reducing perceived latency. For text-to-speech, Vapi offers voices from ElevenLabs, PlayHT, Deepgram and Azure, with options for custom voice cloning. Developers select the model and voice per agent, and can switch mid-call using function calls. ### Tools and function calling Vapi supports function calling, where the agent invokes external APIs during a call to retrieve data, update records or trigger workflows, according to [its function documentation](https://docs.vapi.ai/functions). Developers define functions in their code, specifying parameters and return types, and Vapi's orchestration layer calls the function when the agent determines it is needed. Common use cases include querying a CRM for customer details, booking an appointment in a calendar, checking inventory or updating a support ticket. Function responses are injected into the conversation context, allowing the agent to speak the result to the user. ### Integrations Vapi integrates with CRMs, helpdesks and calendars through its REST API and function calling, according to [its integration documentation](https://docs.vapi.ai/integrations). Teams write custom functions to connect Vapi agents with Salesforce, HubSpot, Zendesk, Calendly or any REST API. Vapi also offers webhooks for call events (call started, call ended, transcript ready), allowing teams to log data in their own systems. The platform does not publish a list of pre-built integrations; all connections are developer-configured. ### Analytics and quality assurance Vapi has a dashboard with call logs, transcripts, recordings and latency metrics, according to [its analytics documentation](https://docs.vapi.ai/analytics). Developers can filter calls by date, agent, outcome or error, and export transcripts for analysis. The platform tracks conversation duration, speech-to-text accuracy (as reported by the underlying provider) and function call success rates. Vapi does not publish built-in sentiment analysis or automated QA scoring; teams export transcripts and analyze them with third-party tools. ### Human handoff Vapi supports call transfer to a human agent using SIP REFER or a webhook to a contact center, according to [its transfer documentation](https://docs.vapi.ai/transfer). Developers define transfer conditions in code (e.g., user requests a person, agent cannot resolve the issue), and Vapi routes the call to a specified phone number or SIP endpoint. The platform passes the call transcript and context to the human agent via webhook. Vapi does not offer a built-in queue or agent desktop; teams integrate with their existing contact center. ### Compliance and security Vapi is SOC 2 Type II certified and offers HIPAA Business Associate Agreements for healthcare customers, according to [its security page](https://vapi.ai/security). The platform encrypts call recordings and transcripts at rest and in transit. Vapi states that it does not train language models on customer data. For GDPR compliance, Vapi offers data residency options and data deletion APIs. Teams deploying Vapi for TCPA-regulated outbound calls or healthcare use cases should review the platform's compliance documentation and consult legal counsel, as compliance depends on how the agent is configured and deployed. ## How much does Vapi cost? Vapi charges $0.05 per minute of conversation time as of October 2026, according to [its pricing page](https://vapi.ai/pricing). This rate covers Vapi's orchestration layer, but does not include telephony, speech-to-text, language model inference or text-to-speech, which are billed separately by the underlying providers. The pricing page does not specify the per-minute cost for telephony or the speech and model layers, stating that costs depend on the providers chosen. _Pricing checked October 2026.

Teams with compliance requirements or those wanting simpler billing often prefer all-in per-minute pricing or per-seat plans. **Build effort.** Vapi is an API-first developer platform that requires code to configure agents, route calls and integrate with business systems. Operations teams, sales leaders and small businesses without engineering resources often need a no-code builder with pre-built templates and visual workflows. **Use-case fit.** Vapi is a general-purpose voice agent platform. Teams running high-volume outbound sales campaigns may prefer a platform with built-in dialer features, lead-list management and sales-specific prompts. Teams needing emotional intelligence or sentiment detection may want a platform that surfaces tone and affect in real time. **Infrastructure control.** Vapi is a hosted platform. Teams with strict data residency requirements, those wanting to avoid vendor lock-in or those building real-time voice applications beyond phone calls may need open-source infrastructure they can self-host. **Component vs platform.** Vapi bundles speech-to-text, language model, text-to-speech and telephony into one platform. Developers who already have a preferred speech provider or who want to swap models without changing platforms may prefer to assemble components themselves. Vapi's strengths include sub-500ms latency, support for over 100 languages and integrations with 20+ providers including OpenAI, Anthropic, ElevenLabs, Deepgram, Twilio, Salesforce and HubSpot, according to [Vapi's homepage](https://vapi.ai/) as of October 2026. Enterprise customers include Amazon Ring, Intuit, New York Life and ServiceTitan, according to [Finsmes](https://www.finsmes.com/2026/05/vapi-raises-50m-in-series-b-funding.html) as of May 2026. ### Vapi vs Retell AI at a glance | Feature | Vapi | Retell AI | | --- | --- | --- | | Pricing model | Platform fee + provider costs | Platform fee + provider costs | | Starting price | $0.05/min platform fee | $0.04/min platform fee | | Build model | API-first | API-first | | Telephony | Twilio, Vonage, others | Twilio, Vonage, others | | Inbound/outbound | Both | Both | | Integrations | 20+ (Salesforce, HubSpot, Zendesk) | 10+ (Salesforce, HubSpot) | | Compliance | SOC 2, HIPAA ($2k/mo), PCI | SOC 2, HIPAA (included), PCI | | Best for | Developers needing broad integrations | Developers wanting lower fees and included HIPAA | Vapi is the closer fit for teams needing integrations beyond CRM and support platforms, because it documents 20+ integrations according to [its homepage](https://vapi.ai/). Retell AI is the closer fit for developers prioritizing platform cost and HIPAA compliance, because its $0.04 per minute platform fee is 20% lower than Vapi's and HIPAA compliance is included in the base plan according to [Retell AI's pricing page](https://www.retellai.com/pricing). ## 1) Retell AI Retell AI is a developer platform for building AI voice agents that answer and place phone calls. The platform charges a $0.04 per minute platform fee, 20% lower than Vapi's $0.05 fee, according to [Retell AI's pricing page](https://www.retellai.com/pricing) as of October 2026. Retell AI suits developer teams building custom voice agents who want to minimize platform costs while maintaining control over speech and language-model providers. **Best for:** Developers building custom voice agents who prioritize lower platform fees and included HIPAA compliance. ### Key capabilities - Custom voice cloning that creates agent voices from sample recordings, according to [Retell AI's documentation](https://docs.retellai.com/voice-cloning) as of October 2026 - Multi-language support with real-time translation during calls, according to [Retell AI's features page](https://www.retellai.com/features) as of October 2026 - WebSocket API for real-time call control and custom telephony integration, according to [Retell AI's API documentation](https://docs.retellai.com/api-reference) as of October 2026 - Native integrations with Salesforce, HubSpot and 10+ other business systems, according to [Retell AI's integrations page](https://www.retellai.com/integrations) as of October 2026 - HIPAA compliance included in the base platform fee with no additional charge, according to [Retell AI's pricing page](https://www.retellai.com/pricing) as of October 2026 ### Pricing Retell AI charges a $0.04 per minute platform fee plus separate costs for speech-to-text, language model, text-to-speech and telephony, according to [Retell AI's pricing page](https://www.retellai.com/pricing) as of October 2026. The pricing page states that typical all-in costs range from $0.25 to $0.30 per minute depending on provider choices. HIPAA compliance is included at no additional charge. The platform offers a free tier with 10 minutes for testing. ### Limitations Retell AI's documentation does not list as many pre-built integrations as Vapi's 20+ according to [Vapi's homepage](https://vapi.ai/), which may require custom development for less common business systems. The platform's pricing model still separates platform fees from provider costs, so teams wanting a single per-minute rate will need to estimate total costs based on usage patterns. The free tier's 10-minute limit is lower than some alternatives that offer 100+ minutes for testing. ### How it compares with Vapi Retell AI is the closer fit for developers who want to minimize platform costs and need HIPAA compliance without a $2,000 monthly add-on, because its $0.04 per minute platform fee is 20% lower than Vapi's and HIPAA is included according to [Retell AI's pricing page](https://www.retellai.com/pricing). Vapi is the closer fit for teams needing a broader integration library or those already using Vapi's documented 20+ integrations according to [Vapi's homepage](https://vapi.ai/). ## 2) Bland AI Bland AI is a developer platform focused on outbound sales calls that charges $0.09 per minute with no separate platform fee.

Volume discounts are available for teams placing more than 100,000 minutes per month, but specific rates are not publicly listed. ### Limitations Bland AI's focus on outbound sales means it reportedly offers fewer features for inbound customer-service use cases compared with general-purpose platforms like Vapi, based on [Bland AI's documentation](https://docs.bland.ai/) as of October 2026. The $0.09 per minute all-in rate is higher than Vapi's $0.05 platform fee for teams that can negotiate lower rates with speech and language-model providers directly. The platform's documentation does not list HIPAA compliance or a business associate agreement option as of October 2026. ### How it compares with Vapi Bland AI is the closer fit for sales teams running high-volume outbound campaigns, because it includes a built-in power dialer, sales-specific prompt templates and batch calling according to [Bland AI's features page](https://www.bland.ai/features). Vapi is the closer fit for teams running both inbound and outbound calls across multiple use cases, because it is a general-purpose platform with broader integration coverage according to [Vapi's homepage](https://vapi.ai/). ## 3) Synthflow Synthflow is a no-code builder for AI voice agents that has a visual workflow editor and pre-built templates for common use cases.

The pricing page states that all plans include speech-to-text, language model, text-to-speech and telephony. A 7-day free trial is available with 20 minutes included. ### Limitations Synthflow's no-code builder reportedly offers less flexibility than API-first platforms for teams needing custom logic, complex integrations or real-time call control, based on [Synthflow's documentation](https://docs.synthflow.ai/) as of October 2026.

LiveKit Cloud charges $0.01 per participant-minute for real-time media streaming, with separate charges for recording, transcription and egress, according to [LiveKit Cloud's pricing page](https://livekit.io/pricing) as of October 2026. The pricing page states that the first 50 participant-hours per month are free. Enterprise plans with volume discounts and dedicated support are available but pricing is not publicly listed. ### Limitations LiveKit is infrastructure, not a complete voice agent platform, so developers must integrate speech-to-text, language model and text-to-speech providers separately and build call-routing logic themselves. Teams without real-time media expertise may face a steeper learning curve compared with platforms like Vapi that bundle all components. The open-source version requires teams to manage their own hosting, scaling, monitoring and security, which adds operational overhead. ### How it compares with Vapi LiveKit is the closer fit for developer teams building custom real-time voice applications who need infrastructure control or want to self-host, because it is an open-source media server that can run on any cloud or on-premises according to [LiveKit's documentation](https://docs.livekit.io/). Vapi is the closer fit for teams wanting a complete voice agent platform with bundled speech, language model and telephony, because it provides all components in one API according to [Vapi's homepage](https://vapi.ai/). ## 5) ElevenLabs ElevenLabs is a text-to-speech API that provides high-fidelity voice synthesis with emotional range and custom voice cloning.

Additional characters cost $0.30 per 1,000 characters on the starter plan, $0.24 per 1,000 characters on the creator plan and $0.18 per 1,000 characters on the pro plan. The pricing page states that enterprise plans with volume discounts are available but pricing is not publicly listed. ### Limitations ElevenLabs is a text-to-speech component, not a complete voice agent platform, so developers must integrate speech-to-text, language model, call routing and telephony separately. Teams wanting a bundled platform will need to assemble multiple providers and manage integration complexity themselves. The character-based pricing model requires teams to estimate text length per call, which can be harder to forecast than per-minute pricing for voice agents. ### How it compares with Vapi ElevenLabs is the closer fit for developers who want to use ElevenLabs' high-fidelity speech synthesis with their own speech-to-text and language-model providers, because it is a component API that integrates with any platform according to [ElevenLabs' API documentation](https://docs.elevenlabs.io/api-reference). Vapi is the closer fit for teams wanting a complete voice agent platform with bundled speech, language model and telephony, because it provides all components in one API according to [Vapi's homepage](https://vapi.ai/). ## 6) Deepgram Deepgram is a speech-to-text API that provides real-time transcription with low latency and support for 36 languages. The platform charges $0.0043 per minute for real-time transcription, according to [Deepgram's pricing page](https://deepgram.com/pricing) as of October 2026.

The pricing page states that custom model training is available on enterprise plans but pricing is not publicly listed. The platform offers a free tier with 12,000 minutes per year for testing. Volume discounts are available for teams processing more than 1 million minutes per month. ### Limitations Deepgram is a speech-to-text component, not a complete voice agent platform, so developers must integrate language model, text-to-speech, call routing and telephony separately. Teams wanting a bundled platform will need to assemble multiple providers and manage integration complexity themselves. The per-minute pricing for speech-to-text is separate from language-model and text-to-speech costs, so teams must estimate total costs across all components. ### How it compares with Vapi Deepgram is the closer fit for developers who want to use Deepgram's speech-to-text with their own language-model and text-to-speech providers, because it is a component API that integrates with any platform according to [Deepgram's API documentation](https://developers.deepgram.com/docs/).

Additional minutes cost $0.20 per minute on the starter plan, $0.15 per minute on the professional plan and $0.10 per minute on the enterprise plan. The pricing page states that all plans include speech-to-text, language model, text-to-speech and telephony. A 14-day free trial is available with 50 minutes included. ### Limitations Thoughtly's focus on sales use cases reportedly means it offers fewer features for inbound customer-service or technical-support calls compared with general-purpose platforms like Vapi, based on [Thoughtly's documentation](https://docs.thoughtly.com/) as of October 2026. The no-code builder offers less flexibility than API-first platforms for teams needing custom logic or complex integrations.

The [Hume AI homepage](https://hume.ai/) states that the platform is available for research and commercial use but does not list pricing plans or per-minute rates. Teams interested in Hume AI should contact the vendor directly for pricing information. ### Limitations Hume AI's pricing is not publicly listed, which makes it harder for teams to estimate costs compared with platforms that publish per-minute rates. The platform's focus on emotional intelligence means it may offer fewer features for use cases that do not require sentiment detection. The documentation does not list HIPAA compliance, SOC 2 certification or native integrations with CRM and support platforms as of October 2026. ### How it compares with Vapi Hume AI is the closer fit for teams building voice agents where emotional intelligence matters, because it provides real-time sentiment detection and emotional expression in synthesized speech according to [Hume AI's features page](https://hume.ai/features). Vapi is the closer fit for teams building general-purpose voice agents across multiple use cases, because it is a platform with broader integration coverage and published pricing according to [Vapi's homepage](https://vapi.ai/). ## How do you choose the right Vapi alternative? The right Vapi alternative depends on your build model, use case, integration requirements, compliance needs and budget predictability. Six criteria help narrow the field. ### Do you need a no-code builder or an API? Operations teams, sales leaders and small businesses without engineering resources should prioritize no-code builders like Synthflow and Thoughtly, which offer visual workflow editors and pre-built templates. Developer teams building custom agents with complex logic and integrations should choose API-first platforms like Retell AI, Bland AI or Vapi, which provide full programmatic control. Teams with real-time media requirements or those wanting to self-host should evaluate infrastructure components like LiveKit, ElevenLabs and Deepgram. ### Will you run inbound, outbound or both? Teams running both inbound and outbound calls across multiple use cases should choose general-purpose platforms like Vapi or Retell AI, which support both directions and offer broad integration libraries. Teams focused on high-volume outbound sales campaigns should evaluate Bland AI or Thoughtly, which include built-in dialer features, lead-list management and sales-specific prompt templates. Teams running only inbound customer-service or support calls should prioritize platforms with strong CRM and ticketing integrations. ### Which systems must the agent write to? Teams needing native integrations with Salesforce, HubSpot, Zendesk and other business systems should verify that the platform documents those integrations on its integrations page. Vapi lists 20+ integrations according to [its homepage](https://vapi.ai/); Retell AI lists 10+ according to [its integrations page](https://www.retellai.com/integrations); Synthflow lists 50+ through Zapier according to [its integrations page](https://synthflow.ai/integrations). Teams with less common systems may need to build custom integrations using webhooks or API calls. ### Do you need a HIPAA business associate agreement? Healthcare providers, telehealth platforms and any team handling protected health information must verify that the platform offers a HIPAA business associate agreement. Vapi charges $2,000 per month for HIPAA compliance according to [CloudTalk's pricing breakdown](https://www.cloudtalk.io/blog/vapi-ai-pricing/); Retell AI includes HIPAA in the base platform fee according to [its pricing page](https://www.retellai.com/pricing). Teams should confirm that the platform's HIPAA option covers all components, including speech-to-text, language model, text-to-speech and telephony, and should consult legal counsel to ensure their deployment meets HIPAA requirements. ### How predictable must the monthly bill be? Teams wanting predictable monthly costs should choose platforms with per-seat or per-agent pricing like Synthflow ($29 to $499 per month) or Thoughtly ($99 to $999 per month), which include a fixed number of minutes and charge overages at a published rate. Teams with variable call volumes should evaluate platforms with per-minute pricing like Vapi ($0.05 per minute platform fee), Retell AI ($0.04 per minute platform fee) or Bland AI ($0.09 per minute all-in), and should estimate total costs by adding speech-to-text, language model, text-to-speech and telephony charges. ### Do you need real-time voice infrastructure or a complete agent platform? Teams building custom real-time voice applications beyond phone calls, those with strict data residency requirements or those wanting to avoid vendor lock-in should evaluate open-source infrastructure like LiveKit, which can be self-hosted on any cloud or on-premises. Teams wanting a complete voice agent platform with bundled speech, language model and telephony should choose Vapi, Retell AI, Bland AI, Synthflow or Thoughtly, which provide all components in one API or builder. ## Frequently asked questions ### What is the best Vapi alternative for non-technical teams?

Teams without engineers may find better value in no-code alternatives like Synthflow ($29 per month) or Thoughtly ($99 per month), and teams with HIPAA requirements should compare Vapi's $2,000 per month HIPAA add-on with Retell AI's included HIPAA compliance. ### How does Retell AI compare with Vapi? Retell AI is the closer fit for developers who want to minimize platform costs and need HIPAA compliance without a monthly add-on, because it charges a $0.04 per minute platform fee (20% lower than Vapi's $0.05 fee) and includes HIPAA in the base plan according to [Retell AI's pricing page](https://www.retellai.com/pricing) as of October 2026. Vapi is the closer fit for teams needing a broader integration library, because it documents 20+ integrations compared with Retell AI's 10+ according to [Vapi's homepage](https://vapi.ai/). Both platforms are API-first, support custom voice cloning and offer similar latency and language support. ### Which Vapi alternative is best for developers building custom voice apps?

The platform provides WebRTC infrastructure, real-time audio streaming with sub-100ms latency and server-side APIs in Go, Python, JavaScript and Ruby.

The platform charges $0.09 per minute all-in with no separate platform fee, making billing simpler for sales teams. Thoughtly is another option for sales teams without engineers, offering a no-code builder with pre-built sales workflows at $99 per month according to [Thoughtly's pricing page](https://thoughtly.com/pricing). ### Do any Vapi alternatives offer HIPAA compliance?
