Why teams search for a Retell AI alternative
- 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.
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.

Tabbly vs Retell AI numbers
| 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 |
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.
