Tabbly vs Retell AI 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 | Retell AI |
|---|---|---|
| Best for | Teams that want to launch inbound/outbound voice agents in Indian and global languages without assembling STT, LLM, TTS and telephony themselves | Product teams that want a polished US-centric voice agent with HIPAA options and a visual conversation flow |
| Not ideal for | Teams that need HIPAA/BAA as the primary buying reason, or a fully outsourced human+AI BPO | India-only contact centres that need 10+ Indic languages, GST invoices and Mumbai residency as the default |
| HQ / centre of gravity | India, with US data-residency option | United States |
| Product type | No-code AI voice-agent platform | Managed voice-agent platform (API + visual flow) |
| 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 | $0.07–$0.31/min depending on model, voice and add-ons |
| Languages | 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages | About 19+ via providers. Public roundups list Hindi, Tamil, Kannada, Marathi, Urdu — not a full Indic set (Telugu/Bengali often missing). |
| 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. | Retell publishes around 600ms in favourable regions. India paths are commonly 800ms+ in third-party tests because of transcontinental routing. |
| Data residency | India / USA data residency (stated on tabbly.io) | US infrastructure; SOC 2 / HIPAA story is US healthcare, not DPDP India residency |
| Builder | No-code agent builder plus APIs; campaigns, recordings, analytics | Visual conversation flow plus API |
| Telephony | 50+ countries, local numbers including +91, unlimited concurrency on published plans | Twilio/Telnyx including India at a published per-min carrier rate; SIP/custom telephony listed as no extra Retell charge |
| Concurrency | Unlimited on published product pages | 20 included on PAYG, more on demand; uncapped on enterprise |
| Billing | INR or USD, exact seconds, self-serve credits | USD |
What Retell AI actually is
Retell sits between a raw developer toolkit and a fully managed agent: you get a flow builder, analytics, and relatively honest per-component pricing. It is a serious US/EU product. For Indian outbound collections or Hindi-English code-switch, it is a workable import, not a native fit.
Where they are strong
- Strong turn-taking and a mature testing/simulation console.
- Clear componentised invoice (infra vs LLM vs TTS vs telco).
- HIPAA, PII redaction and US enterprise compliance path.
What to watch
- Indic language coverage is thinner than India-first vendors.
- USD pricing plus India carrier fees is rarely the cheapest Bharat minute.
- Data residency is not an India-default story.
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.
Retell AI publishes $0.07–$0.31/min depending on model, voice and add-ons. Retell’s public calculator often shows ~$0.11/min (infra $0.055 + LLM $0.04 + TTS $0.015). India Twilio/Telnyx telephony is listed around $0.015/min extra. HIPAA/BAA is an enterprise add-on.
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
Retell AI: About 19+ via providers. Public roundups list Hindi, Tamil, Kannada, Marathi, Urdu — not a full Indic set (Telugu/Bengali often missing).
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. Retell AI is a 19+ 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. Retell AI: Retell publishes around 600ms in favourable regions. India paths are commonly 800ms+ in third-party tests because of transcontinental routing. 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) Retell AI: US infrastructure; SOC 2 / HIPAA story is US healthcare, not DPDP India residency 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.
Retell AI ships Visual conversation flow plus API. Telephony: Twilio/Telnyx including India at a published per-min carrier rate; SIP/custom telephony listed as no extra Retell charge. Concurrency: 20 included on PAYG, more on demand; uncapped on enterprise.
India-only contact centres that need 10+ Indic languages, GST invoices and Mumbai residency as the default
The honest split
Tabbly’s published India rates (₹5.10–₹6.80/min, seconds billing) and 50+ languages including Hinglish are aimed at the same job Retell does for English-first markets. Retell wins if you need HIPAA and a US legal stack. Tabbly wins if your callers, numbers and finance team are in India — or you need one platform that also covers US, UK, SG and AE.
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.
