# Vapi vs Voiceflow (2026): Which should enterprises buy? By Samuel Oram-Jones Vapi and Voiceflow both put an AI agent on a phone line, but Vapi is an API that developers wire together and Voiceflow is a visual studio for customer experience teams. This comparison covers what each runs on, how each bills, what each offers on security and channels, and where Bland fits, as of November 2026. ## Which is better, Vapi or Voiceflow? Bland is the better pick than either Vapi or Voiceflow for enterprise phone calls as of November 2026, because Bland builds and runs every AI model on a call, publishes a self-serve per-minute rate, and Enterprise customers get dedicated orchestration and dedicated GPUs run by Bland. Between the two, Vapi suits developers who choose every provider, and Voiceflow suits a team designing chat and voice agents in a visual builder. Vapi hosts a call at $0.05 a minute and bills a language model, transcription, and voice at provider cost on top. Voiceflow publishes no plan price, only a "Request pricing" route for businesses and a credit table. | Feature | Bland | Vapi | Voiceflow | |---|---|---|---| | AI on each call | Full stack | Outsourced | Mixed | | AI rate per minute | $0.12-$0.14 on self-serve plans | $0.05 hosting only | No | | SOC 2 Type II | Yes | Yes | Yes | | ISO 27001 | Yes | No | Yes | | GDPR | Yes | Yes | Yes | | iMessage | Native | No | No | ## How do Vapi and Voiceflow differ? The biggest difference between Vapi and Voiceflow is who the product is built for. Vapi hands a developer one piece of the call at a time, while Voiceflow hands a CX team a studio with playbooks and workflows. Both rely on language models from other companies, which is where Bland, a full stack provider, differs from both. ### Vapi overview Vapi is a developer platform that hosts voice agents and bills language model, transcription, and voice from other companies at cost on top. Vapi shows a calculator with Deepgram for transcription, OpenAI for the language model, and ElevenLabs for voice, and Vapi says "Models pass-through at cost" and "Provider costs with no markup". Vapi also sells packages. Core is $29 a month, Pro charges 10% of the hosting fee with a $999 monthly minimum, and Premier is sold through sales. Vapi says its EU region is "available only with the Premier Success Package", and Vapi doesn't offer iMessage agents. Teams that want one company answering for every AI part of a call, because its terms say "Vapi does not control, and is not responsible for, any Optional Provider or Customer-Managed Provider", look past Vapi. Can't have calls fail when a provider does, because Vapi says "Without any fallback plan configured, your call will end with an error if your chosen transcription provider fails"? Then a team owns a fallback plan for every provider it picks. Want HIPAA handling without a $2,000 a month add-on, because Vapi prices HIPAA mode as a separate line? That too points away from Vapi. Need the most realistic voices, because Bland Speech v3 ranked first among AI voices on Audio Realism Bench on 4 August 2026 at 1365, and Vapi's highest voice there ranked 4th at 1119? That points to Bland as well.

Pros

Cons

### Voiceflow overview Voiceflow describes itself as a platform for the teams behind AI agents, with Studio to build them, Playbooks for complex tasks, Workflows that follow a business process, Rehearsal to simulate conversations, and Prism for analytics. Voiceflow offers agencies a free trial with usage-based billing, and offers businesses implementation support, "self-serve or fully managed", with deployment "across every channel: voice and chat". Voiceflow says "Avoid model lock-in. Choose from the biggest LLM providers, or bring your own model." Its credit table lists models from Anthropic, Google, Groq, OpenAI, and its own voiceflow-core line, plus speech-to-text from AssemblyAI, Deepgram, ElevenLabs, and others, and text-to-speech from Amazon, Cartesia, ElevenLabs, Google, Microsoft, and Rime Labs. Voiceflow doesn't offer iMessage agents.

### How do Vapi and Voiceflow set up and connect? Vapi and Voiceflow both connect to an existing phone system. Voiceflow says a number can come from Twilio, Vonage, Telnyx, or Voiceflow itself, which provisions a US or Canadian number, and that a team whose numbers stay in its own phone system, PBX, or contact center can connect it over SIP. Vapi includes Vapi Telephony and SIP, with "1 included Vapi phone number", and Twilio inbound at $0.008 a minute and outbound at $0.014. Bland connects to an existing carrier over [SIP](https://docs.bland.ai/agents/sip), the standard link between a phone system and a voice platform, so existing numbers can stay where they are. Bland runs its own SIP signaling and media servers, so every call is set up, hosted, and processed on Bland infrastructure with no third-party telephony provider in the path. ### How do Vapi and Voiceflow handle security and uptime? Voiceflow holds SOC 2 Type II, ISO 27001, GDPR, and HIPAA, and says "Voiceflow does not use customer data to train any machine learning or AI models." Voiceflow also says model providers it integrates are "configured with zero data retention". Voiceflow's BAA terms are unconfirmed as of 5 November 2026, so a healthcare team asks before it builds. Vapi says it is SOC 2 Type II attested and GDPR compliant, and sells HIPAA handling, with a Business Associate Agreement, as a paid add-on at $2,000 a month. A BAA is the contract HIPAA requires before a vendor handles patient information. Vapi offers a 99% uptime SLA on Pro and a higher figure only on Premier, while Bland offers a 99.9% uptime SLA on every plan. A team reviewing either vendor also reviews every AI company behind it. Bland is full stack, so a security team reviews one AI company, and Bland's language model is closed source and developed by Bland itself. ## Which sounds more human, Vapi or Voiceflow? Neither Vapi nor Voiceflow has a voice of its own on Design Arena's Audio Realism Bench as of 4 August 2026, and Bland Speech v3 ranked 1st of 13 AI voices at 1365, second only to real human recordings. Vapi has no voice of its own with a score there. The outside voices a customer can pick on it scored below Bland Speech v3, with GPT Realtime 2 highest, 4th at 1119. Voiceflow has no voice of its own with a score there either, and its text-to-speech companies include ElevenLabs, Cartesia, Google, Microsoft, Amazon, and Rime Labs, none with a model in the blind results. The test has vetted native speakers choosing which of two voices reads one script more like a real person. See [Design Arena's published results](https://notes.designarena.ai/audio-realism-benchmark-measuring-realism-in-audio-models/). ## How much do Vapi and Voiceflow cost? Vapi publishes a hosting rate and Voiceflow publishes a credit table, and neither gives a total for a minute without choosing models, while Bland publishes $0.14 a minute on its self-serve Start plan and $0.12 a minute plus $299 a month on self-serve Build for all of its AI, before phone, as of November 2026. ### Vapi pricing Vapi charges $0.05 a minute for hosting and bills each part at provider cost on top. At the top of each published range that is $0.0099 for transcription, $0.0452 for the language model, and $0.0238 for voice, which adds up to roughly 13 cents a minute before phone. - **HIPAA add-on:** $2,000 a month - **Pro package:** 10% of hosting, $999 monthly minimum - **Extra concurrency:** $10 a month per line - **Language, voice, and transcription:** Billed at provider cost on top of $0.05 hosting ### Voiceflow pricing Voiceflow gives businesses a "Request pricing" route and no plan price, so a buyer gets a quote from sales. Voiceflow's credit table lists $0.005 for each chat message and $0.05 for each minute of phone usage, and lists language model, speech-to-text, and text-to-speech costs in separate tables by vendor and model. Voiceflow says "Every interaction, from chat messages to LLM calls to voice minutes, consumes a certain number of credits depending on the vendor and model you use." A second table for Enterprise lists 10 credits per phone minute and gives no dollar value for a credit. Voiceflow publishes no default stack, so a total for a minute can't be worked out from its pages, and Voiceflow can't be set beside the self-serve $0.14 or $0.12 rates on one basis until a buyer picks models and asks for a quote. ### Bland pricing Bland publishes one number per plan, and that number covers its language model, transcription, and speech with no token charges. A minute is $0.14 on the self-serve Start plan, or $0.12 on self-serve Build with a $299 monthly platform fee. Phone is billed separately, on a customer's own carrier or on Bland's at pass-through cost. Enterprise pricing is custom, set with Bland's sales team. On one basis, before phone, Bland's self-serve Build rate of $0.12 sits below Vapi's roughly 13 cents at the top of each range, and self-serve Start at $0.14 sits above it. The comparison that holds either way is the number of companies setting a price: one at Bland, and four at Vapi once hosting, transcription, language model, and voice are counted. ### What does each Bland plan include? Enterprise is the plan regulated teams buy. It adds native iMessage agents alongside SMS and web chat, warm transfers, guardrails, a BAA, SSO, data residency, dedicated orchestration with dedicated GPUs run by Bland, and forward-deployed engineers who work beside a customer's team, with concurrency contracted to its volume and custom pricing. | Included | Self-serve: Start | Self-serve: Build | Enterprise (custom) | |---|---|---|---| | Price per minute | $0.14 | $0.12 | Custom | | Platform fee | $0 | $299 a month | Contracted to volume | | Transfer time per minute | $0.05 | $0.04 | Custom | | Concurrent calls | 10 | 50 | Custom | | Calls a day | 100 | 2,000 | Unlimited | | Knowledge bases | 10 | 50 | Unlimited | | Voices | 1 | 5 | Unlimited | | Uptime SLA | 99.9% | 99.9% | 99.9% | | Pathways, integrations, and automations | Yes | Yes | Yes | | iMessage, SMS, and web chat | No | No | Yes | | Warm transfers and guardrails | No | No | Yes | | BAA, SSO, and data residency | No | No | Yes | | Dedicated orchestration and GPUs | No | No | Yes | | Forward-deployed engineers | No | No | Yes | ## Why do enterprises pick Bland over both? Enterprises pick Bland over both Vapi and Voiceflow because one company builds every AI model on a call, its self-serve rate is published, and Enterprise customers get dedicated orchestration and dedicated GPUs run by Bland. Bland has more than 250 enterprise customers and has handled over 1.3 billion calls, and it publishes sub-200ms latency. A security team reviews one AI company instead of a chain of them, and finance can price a minute before a sales call. Bland also runs branded iMessage agents natively on Enterprise, which send and receive photos, videos, files, voice memos, and tapbacks, and share the same pathways as its voice agents. On Enterprise, forward-deployed engineers work beside a customer's team on its first agent. Bland also moves an agent from staging to production only when chosen simulated test cases pass chosen judges, and its evaluations grade call audio as well as the transcript, so tone and satisfaction count. ![Bland's trust page, which reads Pass security review on day one, with voice, text to speech, transcription, and language models all owned and operated by Bland.](/images/compare/bland-trust.jpg)
