RexaThe short answer
Bolna publishes 6¢ per minute with volume discounts, and supports bring-your-own-keys for language, speech and voice providers so you can lower cost by supplying your own accounts. Rexa.ai charges 10¢ per minute with those components included and nothing to supply. Bolna is the stronger choice for Indian-language calling; Rexa is the stronger choice when you want nothing to assemble and a compliance evidence trail included.

Frequently asked questions
- Is Bolna cheaper than Rexa.ai?
- Bolna’s published rate is 6¢ per minute against Rexa’s 10¢. Bolna also supports bring-your-own-keys, which can lower the platform rate further but adds your own provider bills. Rexa’s 10¢ includes speech, model, voice and recordings, and the phone line too on the default setup where Rexa provisions the number — nothing further to pay unless you choose to bring your own carrier account, which that carrier then bills you for. So the comparison depends on whether you want to run provider accounts yourself.
- Which platform is better for Indian-language calling?
- Bolna, on published coverage. It documents support for more than ten vernacular Indian languages including Hinglish, Hindi, Tamil and Telugu. Rexa.ai is English-first. If Indian-language calling is your primary use case, that is a real advantage and we would rather say so than obscure it.
Scope, limitations, and sources
Bolna’s 6¢ rate and Rexa’s 10¢ rate are both per-minute but do not necessarily cover identical components; Bolna’s pricing page does not fully specify which of speech, model and telephony are bundled at the base rate. Where you supply your own provider keys to Bolna, your total cost includes those providers’ bills, which are outside both vendors’ published pricing. Language coverage is compared as published, not as measured.
