Vapi Alternatives: Retell AI Pricing, Vapi vs Retell and Vapi Competitors Compared per Minute

The main Vapi alternatives are Retell, Bland, ElevenLabs Agents and Synthflow, and they differ less in features than in how they bill a minute. Retell copies Vapi's model of a platform fee plus pass-through models. Bland and ElevenLabs sell one bundled rate. Synthflow sells annual enterprise contracts that start at $30,000. On a small model, Vapi is still the cheapest per minute, so switching only saves money if you are paying for something Vapi charges extra for, usually concurrency or support.

Nearly every list of Vapi alternatives that ranks today was published by one of the alternatives. We have no voice platform to sell, so the numbers below come straight from each vendor's own pricing page, read on September 17, 2026, and are put side by side at the same call volumes. For the full breakdown of Vapi's own bill, including its new Core and Pro packages, see Vapi pricing per minute and per month.

Vapi alternatives compared by price

Two open-source frameworks, LiveKit and Pipecat, also come up in every comparison. They replace Vapi's orchestration with code you host yourself, so the platform fee disappears and is replaced by engineering and hosting time. They make sense for a team that already runs real-time infrastructure, and rarely for anyone else.

What each Vapi alternative costs per month

This table prices a US phone line at three volumes. Vapi and Retell show a range because the model you choose moves the bill; the Retell range runs from GPT 5.4 mini to GPT 5.4 with Retell's platform voice and its US Twilio rate. Bland includes the model but not telephony. ElevenLabs excludes both the LLM and telephony, so its figure is a floor.

The Bland row needs one assumption: Start allows 100 calls a day, which at three-minute calls is about 9,000 minutes in a 30 day month. Past that you are on Build, where $299 a month plus $0.12 a minute only beats Start's $0.14 above 14,950 minutes. The ElevenLabs rows work because every plan's included minutes are priced at the same $0.08: Pro's $99 buys 1,238 minutes, Scale's $299 buys 3,738 and Business's $990 buys 12,375, and extra minutes cost $0.08 too. The plan you pick really buys concurrency, from 20 calls on Pro to 40 on Business.

Vapi vs Retell: the pricing difference that matters

Retell is the closest like-for-like Vapi alternative, and its pricing is built the same way, so the comparison comes down to four lines.

On per-minute price Vapi wins, by about 1 cent a minute against Retell's own voices and about 3 cents against Retell's ElevenLabs voices, before the model. That is $100 to $300 at 10,000 minutes. Retell wins on concurrency: 20 included lines would cost $160 a month on Vapi. So a line with steady traffic is cheaper on Vapi, and a small line with sharp peaks, like a clinic that gets every call at 8 a.m., can be cheaper on Retell.

Retell AI pricing for add-ons

Retell prices its extras per minute, which keeps them visible: knowledge base $0.005, advanced denoising $0.005, safety guardrails $0.005, PII removal $0.01, batch calling $0.005 per dial, branded caller ID $0.10 per outbound call and AI quality assurance $0.10 a minute after 100 free minutes. A line using the knowledge base, denoising and PII removal adds $0.02 a minute, or $200 at 10,000 minutes, so price the add-ons you actually need before you compare headline rates.

Bland: one rate, with caps

Bland's pitch is "No token charges. No model-provider pass-throughs." Start costs $0.14 a minute with no platform fee and no card, and Build costs $0.12 a minute plus $299 a month. Both include the LLM, transcription and voice, and telephony is billed on your own carrier or Bland's at pass-through cost. Transfer time is billed separately at $0.05 or $0.04 a minute.

The trade is the limits. Start allows 10 concurrent calls, 100 calls a day and 100 an hour; Build allows 50 concurrent, 2,000 a day and 1,000 an hour. Enterprise removes the caps and adds on-premises or VPC deployment, a BAA, SSO and data residency. If you want to stop tracking model prices entirely, Bland is the cleanest bill here. If you want to pick the cheapest model each quarter, it is the wrong design.

ElevenLabs Agents and Synthflow

ElevenLabs lists its Agents pipeline at $0.08 a minute, the lowest platform rate in this comparison, with burst pricing at $0.16 a minute when you exceed your concurrency limit. Its own FAQ is clear that "the LLM model and any telephony are billed separately on top, based on usage," so compare it with Vapi's hosting plus transcriber plus voice, not with Vapi's hosting alone. On that basis it is close to Vapi and ahead of it when you want ElevenLabs voices anyway.

Synthflow publishes no self-serve price on its pricing page. It says enterprise contracts "start at $30,000 annually" and are scoped around call volume, concurrency, telephony, integrations and security review. That is a different purchase: you are buying implementation and ongoing optimization, not minutes. It suits a contact center replacing an IVR, not a team testing one line.

Which Vapi alternative should you choose?

Stay on Vapi if you have engineers, steady traffic and a cheap model, because nothing here beats its per-minute bill. Move to Retell if concurrency or the free 20 lines matter more than a cent or two a minute. Pick Bland if finance wants one predictable rate that includes the model. Look at ElevenLabs if voice quality is the whole point. Talk to Synthflow only when you want someone else to run the rollout under an annual contract.

All five are platforms for building a voice agent, and many businesses do not want to build one. A dental office or a home services company that simply needs its phone answered, calls booked and messages taken is usually better served by a finished AI receptionist that answers and books calls than by a developer platform billed by the component.

It also pays to check how many of those calls should be phone calls at all. When most of them are order status, refunds or the same support questions, a ready-made agent working your help desk and inbox deflects them before they cost a minute. Our catalog of AI agents for customer service lists support, order and refund agents with a flat monthly price and their permissions shown up front, and our comparison of Fin's per-resolution pricing shows what the outcome-priced option costs instead.

Vapi alternatives questions

What is the cheapest Vapi alternative?

On list price per minute, ElevenLabs Agents at $0.08 a minute is the lowest, but the LLM and telephony are billed on top. Among platforms with the model included, Bland Start at $0.14 a minute is the simplest, with a cap of 100 calls a day. Vapi itself stays cheapest on a small model at about $0.08 a minute all in.

Is Retell AI cheaper than Vapi?

Usually not per minute. Retell charges $0.055 for voice infrastructure plus $0.015 for its platform voice and $0.015 for US Twilio calls, against Vapi's $0.05 hosting fee with free Vapi numbers. Retell includes 20 concurrent calls where Vapi includes 4, so small teams with busy peaks can come out ahead on Retell.

Does Retell AI have a monthly fee?

No. Retell pay as you go has no platform fee and no contract. You get $10 of free credit and pay $0.07 to $0.31 a minute depending on the model and voice. Enterprise is custom priced with a dedicated server option, SSO and 24/7 support.
