Vapi Alternatives in India: Self-Hosted and Open-Source Options
Vapi is one of the best-known developer platforms for voice agents, and many Indian teams try it first. Then the questions start: how do the per-minute costs add up in rupees, how good is Hindi or Tamil on a real phone call, can it use an Indian SIP trunk, and where does the call audio go? That is usually when people start searching for Vapi alternatives in India.
This guide groups the alternatives into three types, explains what each is good for, and gives you a checklist to compare them honestly. We make one of the options, so we will be clear about where it fits and where it does not.
Why Indian teams look beyond Vapi
Vapi is a hosted orchestration layer: you configure an assistant, plug in providers and it runs the call. That model works well for many teams. The reasons Indian teams look elsewhere tend to be specific:
- Stacked per-minute costs. Third-party reviews in 2026 describe a platform fee of about $0.05 per minute on Vapi’s self-serve plan, with speech, LLM and telephony billed on top. Check Vapi’s current pricing page before you rely on any figure. For high-volume Indian calls, any dollar-denominated platform fee becomes a large share of the cost.
- Indian language quality. You can bring Indian speech providers into most platforms, but defaults and examples are usually English-first.
- Indian telephony. Many Indian businesses already have a PBX and a SIP trunk from an Indian operator, and want the AI to plug into that rather than buy new numbers abroad.
- Data residency and DPDP. Hospitals, banks and government projects often want call audio and transcripts to stay on their own servers. A hosted-only platform cannot offer that.
Type 1: open-source voice agent frameworks
If you have developers and want full control, frameworks are the most flexible option.
- Pipecat is an open-source Python framework (BSD-2-Clause) for real-time voice and multimodal pipelines. You assemble the transport, STT, LLM and TTS yourself.
- LiveKit Agents is Apache 2.0 and built on LiveKit’s WebRTC stack. You can self-host, but SIP telephony is a separate piece to deploy and operate.
- Dograh is described as an open-source, self-hostable platform with a visual workflow builder, closer in feel to a hosted product.
- Asterisk-native projects connect directly to an existing Asterisk PBX. Our guide to open-source Asterisk AI voice agents covers them.
The trade-off: you own everything, including turn-taking, barge-in, telephony edge cases, cost tracking and on-call support. Licences and features change, so check each repository yourself.
Type 2: hosted voice AI platforms
Hosted platforms are the closest like-for-like swap. Globally, Retell AI is the usual comparison; we have a separate page on Retell AI alternatives. In India, Bolna, Sarvam AI and several others offer voice agent products aimed at Indian languages and use cases. Features, pricing and deployment options vary and change often, so compare them on a current demo rather than a blog table, including this one.
Hosted platforms are fastest to start with. The limits are the same as Vapi’s in principle: your data runs through someone else’s infrastructure, and you pay their margin on every minute.
Type 3: self-hosted voice AI gateways and platforms
The third group sits between the two. You get a product that handles telephony, speech and conversation flow, but you run it on your own servers or in your own cloud account, and you bring your own provider keys. This suits teams that want control and DPDP comfort without writing a voice stack from scratch. We compare the two deployment styles in self-hosted vs cloud voice AI.
Comparison at a glance
| Factor | Vapi (hosted) | Open-source framework | Indian hosted platform | Self-hosted gateway |
|---|---|---|---|---|
| Time to first call | Fast | Slow: you build it | Fast | Medium |
| Data on your servers | No | Yes | Usually no; check | Yes |
| Indian languages | Via provider choice | Via provider choice | Usually a focus | Via provider choice, often Indian-first |
| Uses your Indian SIP trunk / PBX | Possible, check setup | Yes, you build it | Varies | Yes |
| Platform fee per minute | Yes | None (your hardware and time) | Usually yes | Often flat or none |
| Who fixes it at night | Vendor | You | Vendor | You, with vendor support |
How to choose: a checklist
- Run the cost maths in rupees. Estimate your monthly minutes and add every layer: telecom, STT, LLM, TTS, platform. Our post on AI calling agent prices in India shows how.
- Test your languages on real calls. Ten test calls in Hindi and your regional language, from mobile phones, tell you more than any feature list.
- Check telephony fit. Can it use your existing trunk, PBX and caller IDs? Can it transfer to your human agents?
- Ask where data goes. Audio, transcripts and recordings: which providers, which countries, how long kept? Read our note on the DPDP Act for AI voice agents.
- Check lock-in. Can you switch STT, TTS or LLM providers without rebuilding the agent?
- Be honest about your team. An open-source framework is cheap only if you have engineers with time to maintain it.
Moving from Vapi to another platform
If you already have assistants running on Vapi, switching does not have to be a big-bang project. A practical path:
- Export what you have. Save your system prompts, tool definitions, provider choices and any webhook payload formats.
- Pick one low-risk flow. An after-hours inbound line or a reminder campaign is easier to move than your main sales line.
- Rebuild the telephony first. Connect the new platform to your SIP trunk or PBX and make a few test calls before adding any AI logic.
- Port the prompt and tools. Most prompts move with small edits. Tools usually need new endpoint wiring.
- Run both side by side. Split a small share of calls to the new setup for two weeks and compare transcripts, completion rate and cost per call.
- Switch over gradually. Move the rest of the traffic once the numbers hold up.
How VEXYL fits
VEXYL is a self-hosted-first option built in India. The VEXYL Vapi alternative page has a full comparison; here is the short version.
- Runs where you want. Self-hosted on your servers (single binary, Docker or Kubernetes), or on VEXYL Cloud if you prefer hosted.
- Plugs into your phones. SIP trunk, Asterisk AudioSocket, FreePBX and documented IP-PBX brands like Panasonic, Avaya IP Office and Grandstream.
- Bring your own providers. STT from Sarvam, Google, Deepgram, Groq, Gemini or the self-hosted VEXYL-STT; TTS from Sarvam, Google, Gemini, ElevenLabs, Smallest AI, Deepgram or Azure; any LLM through LiteBot, n8n or your own API.
- Simple pricing. A free Developer edition (4 concurrent calls), Professional at $49 for 25 concurrent calls, and custom Enterprise plans. You pay your providers directly.
Where it is not the best fit: if you have no server and no one to look after one, and you want a no-code builder live in an hour, a hosted platform may suit you better. VEXYL Cloud is the middle path there.
The one cost figure we can share from a real deployment: a live hospital in India ran at about ₹0.83 per minute of AI call time.
FAQ
What is the best Vapi alternative in India?
It depends on your priority. For full control and data residency, a self-hosted gateway or an open-source framework. For the fastest start, a hosted platform. Test two or three on your own calls before deciding.
Is there an open-source Vapi alternative?
Yes. Pipecat and LiveKit Agents are open-source frameworks, and there are open-source Asterisk projects. They need engineering work to reach production quality.
Are there cheaper Vapi alternatives?
Self-hosted options remove or flatten the per-minute platform fee, so you mainly pay for speech, LLM and telecom. Whether that is cheaper overall depends on your volume and your team’s time.
Can I migrate my Vapi assistant to another platform?
Usually you can reuse the prompt, tools and provider choices. Telephony setup, webhooks and call flow logic need to be rebuilt on the new platform.
