Vapi Alternative: Adya vs Vapi AI
Vapi is a developer platform: you pay a hosting fee per minute, then the speech, model, voice and carrier costs separately. Adya is one price for a finished agent. Here is what that means on a real Indian bill.
What is Vapi, and how is Adya different?
Vapi charges $0.05 a minute for hosting and passes through speech-to-text, LLM and text-to-speech at provider cost, with telephony billed by your carrier. Its own estimate for 1,000 minutes is $82–129 a month before telephony. Plans add concurrency, retention and support; HIPAA is a $2,000 a month add-on.
Adya is one AI agent that answers phone calls, website chat, WhatsApp and email from a single inbox, at ₹6 a minute with telephony included and an Indian number on the Growth plan.
Choose Adya if…
- You want a working agent this week, not a voice stack to engineer
- You need Indian numbers and INR billing with GST
- WhatsApp, chat and email matter as much as calls
- You want a predictable monthly bill instead of five usage meters
Choose Vapi if…
- You have engineers and want full control over every model and provider
- You are building a voice product of your own on top of the platform
- You need HIPAA with a BAA in the US
- You want to pass model costs through with no markup

Vapi vs Adya: FAQs
As of 12 October 2026 Vapi charges $0.05 a minute for hosting plus provider costs for the transcriber, model and voice. Its own calculator puts 1,000 minutes at $82–129 a month before telephony, which your carrier bills separately.
Usually not once everything is added. At ₹92 to the dollar, 1,000 minutes on Vapi's cheapest models is about ₹7,636 before telephony, and up to ₹11,868 with larger models. Adya Growth is ₹10,999 for 1,000 minutes with telephony, an Indian number and 5,000 chat conversations included.
In practice, yes. Vapi is a platform you build on through its API and dashboard. Adya is a finished agent: you add your knowledge base, connect channels and go live from the console.
Vapi's pricing page lists voice transports — phone, SIP, WebRTC and WebSockets — not WhatsApp. Adya answers WhatsApp, website chat, email and phone calls from one agent.
Yes, as an add-on at $2,000 a month with a BAA. Adya does not offer HIPAA or hold SOC 2 today; it aligns with India's DPDP Act and encrypts data in transit and at rest.
