Why do teams look for a Vapi alternative?

Most often for cost predictability. Vapi’s 5¢ per-minute platform fee excludes speech-to-text, language model and text-to-speech, which are passed through at cost, so the effective rate depends on model selection and is known only after the fact. Teams that want a single modellable number tend to look for a bundled platform.

Is there a Vapi alternative that includes phone numbers?

Rexa.ai includes phone numbers in its 10¢ per-minute rate and also supports bringing your own telecom account. Bolna includes a free phone number for the first 30 days on its Pilots plan. Deepgram does not provide telephony at all, as it sells speech APIs rather than a calling platform.

Alternatives

Vapi alternatives

Teams usually look for a Vapi alternative when they want predictable per-minute cost or telephony included, rather than a platform fee plus pass-through model costs.

The short answer

The main reason teams evaluate alternatives to Vapi is billing shape, not capability. Vapi charges a 5¢ per-minute platform fee and passes speech, model and voice costs through at cost, so the final number varies with your model choices. If that variability is the problem, look for a bundled per-minute platform. If it is not a problem, Vapi is a strong developer platform and switching may not be worth it.

Stay with Vapi

You want to choose models per agent and are comfortable reconciling several usage bills. Model-level control is a real advantage and pass-through pricing can be cheaper at scale if you tune the stack.

Rexa.ai

You want one all-inclusive per-minute rate with recordings and live human handoff included and a phone number provisioned for you by default, keeping the option to bring your own carrier, and compliance controls built in rather than assembled.

Bolna

You are calling in Indian languages, or you already hold your own model and voice provider accounts and want bring-your-own-key pricing.

Deepgram

You are building your own voice product and want best-in-class speech components rather than a finished calling platform. You supply the telephony and application layer.

Synthflow

You are an enterprise buyer who needs a scoped implementation, MSA and DPA, and named launch support, and can accommodate an annual contract.

Scope, limitations, and sources

This survey covers publicly documented pricing and positioning only. It does not rank platforms on latency, voice quality, accuracy or reliability, none of which can be established from public pages. Vendor pricing changes; the access dates below say when each page was last read. Rexa.ai publishes this page and has an obvious interest in it — the options above are listed with their genuine strengths so you can discount ours accordingly.
