You want one price, Indian and global languages, +91 numbers, and a console your ops team can edit without deploying code.
You have engineers, you need a specific model or on-prem tool loop, and most of your traffic is not India PSTN.
Tabbly vs Vapi side-by-side
Public figures, October 2026. “Loaded minute” means speech models + telephony when the vendor splits them. Re-check the vendor before you buy.
| Dimension | Tabbly | Vapi |
|---|---|---|
| Best for | Teams that want to launch inbound/outbound voice agents in Indian and global languages without assembling STT, LLM, TTS and telephony themselves | Engineering teams that want to pick their own STT, LLM and TTS and orchestrate them over an API |
| Not ideal for | Teams that need HIPAA/BAA as the primary buying reason, or a fully outsourced human+AI BPO | Non-technical ops teams in India who need a rupee price, a local number and an agent live today |
| HQ / centre of gravity | India, with US data-residency option | United States |
| Product type | No-code AI voice-agent platform | Developer voice-AI infrastructure |
| Price / minute (public) | From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month | $0.05/min Vapi hosting; STT, LLM, TTS and carrier billed separately |
| Languages | 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages | 35+ via whatever speech vendors you wire in. Indic quality is only as good as that stack; Hinglish is not a first-class product promise. |
| Latency (public) | India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. | Vendor materials cite sub-600ms in good regions. Independent India write-ups often see 800ms–1.4s because media typically leaves India. |
| Data residency | India / USA data residency (stated on tabbly.io) | US-centric hosting; India data residency is not a public default |
| Builder | No-code agent builder plus APIs; campaigns, recordings, analytics | API-first (assistants, squads, tools). Strong for developers, weak as a business console. |
| Telephony | 50+ countries, local numbers including +91, unlimited concurrency on published plans | Vapi telephony or BYO SIP. Indian DIDs and TRAI/DND workflows are not the product’s centre of gravity. |
| Concurrency | Unlimited on published product pages | Capped on public packages (examples: 4 on usage, 10–30 on paid success packages) |
| Billing | INR or USD, exact seconds, self-serve credits | USD prepaid |
What Vapi actually is
Vapi is the default developer platform for voice agents: you compose speech-to-text, a model and a voice, then attach telephony. That flexibility is the point. It is not an India-first calling product. If your callers are in Bharat, mixing Hindi and English, and you care about rupee unit economics and where the audio sits, you will spend extra time on telephony, residency and language tuning that Tabbly already treats as product.
Where they are strong
- Largest model marketplace and the most control over the cascade.
- Clean developer DX, webhooks and custom tools.
- Good fit if you already run Twilio/Telnyx and have backend engineers.
What to watch
- The $0.05 headline is hosting only — real minutes cost more.
- India latency, Hindi/Hinglish and +91 compliance are on you.
- Concurrency and retention are metered by plan.
Price per minute — the loaded number
Tabbly’s published card is From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month. Tabbly bills to the second. Indian numbers are listed around ₹450/month on the enterprise calculator; telco on India PSTN is a small add-on (about 0.75 paisa/min). Public voice-agent rates are $0.05/min PAYG, $0.04 committed, India ₹6.80 / ₹5.10 from 5k minutes.
Vapi publishes $0.05/min Vapi hosting; STT, LLM, TTS and carrier billed separately. Vapi’s own calculator examples in 2026 land around $0.08–$0.13/min all-in before India PSTN premiums. BYOK avoids their model markup but you still pay providers.
Finance teams should model three lines: (1) the vendor’s AI/hosting meter, (2) STT/LLM/TTS if those are BYO, (3) PSTN. A ₹3 or 6¢ headline that excludes the carrier is not cheaper than a ₹5.10 committed Tabbly minute until you add telco. Conversely, Tabbly is not automatically cheaper than VoiceCallingAI’s ₹3 pack or Sarvam’s ₹3.50 model-included PAYG on pure India traffic — those vendors can win on rupees. Tabbly’s commercial case is seconds billing, language coverage, and India + export on one invoice.
Languages
Tabbly: 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages
Vapi: 35+ via whatever speech vendors you wire in. Indic quality is only as good as that stack; Hinglish is not a first-class product promise.
For India, the test is not “do they list Hindi.” It is Hinglish code-switch, South Indian languages on the same agent, and whether English/Arabic/Spanish are available if you later call Dubai or Singapore. Vapi is a 35+ language story. Tabbly is a 50+ language story with Indic as a first-class set, not an add-on.
Latency and data residency
Latency. Tabbly: India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. Vapi: Vendor materials cite sub-600ms in good regions. Independent India write-ups often see 800ms–1.4s because media typically leaves India. Ignore US lab milliseconds for a Jio caller. Ask for a recorded +91 round-trip: connect-to-first-word, barge-in, and time-to-interrupt.
Residency. Tabbly: India / USA data residency (stated on tabbly.io) Vapi: US-centric hosting; India data residency is not a public default DPDP is a contract line, not a homepage adjective. If you are regulated, get the region and subprocessors in writing.
Builder, telephony, concurrency
Tabbly ships No-code agent builder plus APIs; campaigns, recordings, analytics, 50+ countries, local numbers including +91, unlimited concurrency on published plans, concurrency unlimited on published product pages.
Vapi ships API-first (assistants, squads, tools). Strong for developers, weak as a business console.. Telephony: Vapi telephony or BYO SIP. Indian DIDs and TRAI/DND workflows are not the product’s centre of gravity.. Concurrency: Capped on public packages (examples: 4 on usage, 10–30 on paid success packages).

The honest split
Tabbly sells a finished voice-agent product: no-code builder, 50+ languages including vernacular Indian ones, published INR and USD rates, India/US residency, and local numbers in 50+ countries. Vapi sells the substrate. Choose Vapi when you want to own every provider choice. Choose Tabbly when you want agents on the phone this week without standing up a voice stack.
Buying checklist
- Get a loaded-minute quote (models + India PSTN + number rental), not a hosting-only headline.
- Run 20 Hindi and 20 English live calls on +91. Score completions, not demo polish.
- Confirm language list against your actual states — Tamil and Telugu drop off many “Hindi + English” tools.
- Write down data region, retention, and whether recordings leave India.
- If you might call the US, UK, SG or AE later, do not lock into an India-only vendor without an exit.
