Bolna AI's published pricing, as of September 2026, has three options: pay-as-you-go credit top-ups, a Pilots plan of 12,000 minutes at $0.06 per minute (shown on its site as Rs 5.52 per minute, effectively $0.05 with a 20 percent bonus credit) with up to 100 concurrent calls, and custom Enterprise pricing. New accounts get $5 in free credits to try it, and you can bring your own API keys for the speech and LLM providers (Bolna pricing).
Below: what each plan includes, what the per-minute price does and does not tell you, whether Bolna is really open source, why people search "Exotel vs Bolna", and how Bolna compares with its alternatives.
Bolna AI pricing plans
| Plan | Price | What you get |
|---|---|---|
| Free credits | $5 on signup | Build an agent and place test calls |
| Pay-as-you-go | Credit top-ups, no commitment | Flexible usage |
| Pilots | 12,000 minutes at $0.06/min (Rs 5.52/min); effective $0.05/min with 20% bonus | Up to 100 concurrent calls, one pre-configured voice agent, free phone number for the first 30 days |
| Enterprise | Custom, committed volume | Custom integrations and deployment, priority support, dedicated account manager |
On the Pilots plan, 12,000 minutes at Rs 5.52 works out to about Rs 66,240 up front. That suits a team that already knows it will run a meaningful volume; smaller teams usually start on pay-as-you-go.
What does Bolna's per-minute price include?
Bolna's pricing page presents a bundled per-minute rate and does not itemize speech-to-text, the LLM, text-to-speech and telephony separately. Before you compare it with another platform, ask four questions:
- Is telephony included, or billed by your telephony provider (Exotel, Plivo, Twilio) on top?
- Which models are included at that rate, and what changes if you pick a premium voice or LLM?
- What does bring-your-own-keys cost? Bolna supports BYOK; confirm the platform fee when you supply your own keys.
- How is a call billed? Per second or rounded up to the minute, and are unanswered attempts charged?
The same four questions apply to every voice AI vendor. Our AI voice agent pricing breakdown explains why headline per-minute prices are hard to compare directly.

Is Bolna AI open source?
Partly, and the distinction matters. Bolna's GitHub repository describes itself as an "end-to-end open source production ready framework" for building voice applications, released under the MIT license (GitHub). But the same repository explains that the hosted APIs and the no-code dashboard are closed source, built on top of that framework.
So you have two ways to use Bolna:
- Self-host the open-source framework. The software is free; you pay for models, telephony and servers, and your engineers build and run it.
- Use the hosted platform. You pay Bolna's usage pricing and get the dashboard, hosted infrastructure and support.
Exotel vs Bolna AI: what is the difference?
"Exotel vs Bolna AI" is a common search, but the two are not direct competitors. Exotel is a cloud telephony provider: it supplies your Indian numbers and carries the calls. Bolna is a voice AI platform: it runs the conversation. Bolna's own documentation lists Exotel as a telephony provider you can connect with your existing Exotel credentials, for both inbound and outbound calls.
In practice the question is which voice AI platform to put on top of Exotel. If you already have Exotel numbers, our Exotel AI calling setup guide shows how the connection works on the Exotel side, which is the same whichever platform you choose.

Bolna vs Edesy: how do they differ?
They are the closest like-for-like pair: both self-serve, both India-focused, both support Exotel, Plivo, Twilio and SIP, and both let you bring your own AI keys. The differences are practical:
| Bolna | Edesy | |
|---|---|---|
| Open-source core | Yes, MIT framework | No |
| Pricing currency | USD, with INR shown | INR plans |
| BYOK platform fee | Confirm with Bolna | Rs 1.5 per minute, published |
| Free start | $5 credits | Rs 50 trial credits, no monthly fee on pay-as-you-go |
| Outbound campaigns | Batch calling | Campaigns with daily calling windows, retries by outcome on a multi-step schedule, up to 100 parallel calls, and calls spread across several numbers |
| Indian languages | Hindi, Hinglish, Tamil, Telugu and more | Hindi, English, Hinglish and 20+ Indian languages |
If an open-source core you can self-host is the deciding factor, Bolna wins. If you want INR pricing, a published BYOK fee and detailed outbound controls, Edesy is worth a test. The quickest way to decide is to build the same agent on both with the free credits and compare real calls. See also our Bolna alternatives page and the Edesy vs Bolna comparison.
