Las mejores alternativas a Vapi para construir o comprar una recepcionista con IA

Alternativas

1. 1

   Retell AI

   Retell AI

   Nuestra elección

   ★★★★★

   –

   A pay-as-you-go platform for building AI phone agents: you set up the agent, number and integrations, and pay per minute for each part of the stack.

   Puntos fuertes

   • No platform fee or contract: start with $10 in free credits and pay per second of use
   • A dashboard builder with templates, plus an Auto Receptionist setup that starts from your website
   • Books into Cal.com, Calendly and GoHighLevel and syncs calls to HubSpot, Salesforce and other CRMs
   • Keep your existing number over SIP, or buy one for $2 a month
   • Self-serve HIPAA BAA at no extra fee, plus SOC 2 Type II
   • Agents can speak 55 languages, depending on the voice and speech-recognition providers chosen

   Puntos débiles

   • You build and tune the agent yourself, or pay an implementation team or partner to do it
   • The per-minute price stacks several fees (platform, model, voice, telephony, add-ons), so the real cost depends on choices a business owner may not understand
   • Silence and hold time are billed, and numbers, SMS and extra concurrency cost extra each month
   • Retell's own pages disagree on details such as the free allowance (60 minutes or $10 in credit)

2. 2

   Bland AI

   Bland

   ★★★★★

   19,99 US$/mes

   An enterprise voice AI platform running on its own models, with one per-minute rate that covers the AI; self-serve plans start at $0.14 a minute.

   Puntos fuertes

   • One per-minute rate covers the AI, so there are no separate model, voice or transcription bills
   • Free Start plan with an inbound number and no card required
   • Runs on its own models, with on-premises or VPC deployment for enterprise customers
   • Speaks 40+ languages and can switch language mid-call
   • HIPAA with a BAA, SOC 2 Type II and GDPR for regulated businesses

   Puntos débiles

   • Pitched at enterprises: the receptionist is yours to build, and hands-on help from Bland's engineers comes with Enterprise
   • Texting, warm transfers and the HIPAA BAA are Enterprise-only (texting also comes with the Agent Phone plan)
   • The Start plan caps you at 100 calls a day, and transferred minutes cost extra
   • Lower rates need the $299-a-month Build plan
   • Booking is documented only for Cal.com

3. 3

   Synthflow

   Synthflow

   ★★★★★

   –

   An enterprise voice AI platform for contact centers and multi-location brands, sold only as a custom annual contract with no per-minute rate or trial.

   Puntos fuertes

   • Synthflow's engineers can build and launch the agents for you
   • Connects to contact-center phone systems (Five9, RingCentral, 8x8, Zoom) and CRMs such as Salesforce and HubSpot
   • Keep your current carrier or phone system over SIP, or use your own Twilio account
   • HIPAA with a BAA, SOC 2 Type II, ISO 27001 and US or EU data hosting
   • Agents speak 30+ languages and can switch language mid-call

   Puntos débiles

   • Enterprise only: an annual contract with no published price, no trial and no self-serve signup
   • Built for contact centers and multi-location brands rather than a single small business
   • Launch takes weeks, depending on integrations, phone system and security review
   • Choosing OpenAI models requires an Enterprise plan; Claude and custom models aren't supported

   Rally Commerce, Inc. (dba Rosie)

   ★★★★★

   49 US$/mes

   Puntos fuertes

   • Published, self-serve prices from $49 a month for 250 minutes, with a 7-day free trial
   • No per-minute overage: going over your minutes moves you to the next plan's flat price
   • No contract or cancellation fee; cancel from the admin anytime
   • Trains itself from your Google Business Profile and website, with setup in as little as 10 minutes
   • English and Spanish, call recordings, transcripts and summaries on every plan, plus iOS and Android apps

   • CRMs connect only through Zapier for now; direct CRM integrations are still in the works
   • Call recordings are deleted automatically after 30 days
