Retell AI alternatives: SpeakEdge and four other voice AI platforms compared

What each one costs, who builds the agent, and who it suits.

Prices taken from each company's own pricing page, checked on 3 October 2026.

Short answer: Retell AI is a pay-as-you-go platform that you or a developer builds on. If you want more control over each provider, look at Vapi. If you want a fixed rate per minute, look at Bland AI. For Indian languages on a build-it-yourself platform, look at Bolna. If you would like the agent set up for you on your website, phone and WhatsApp for a monthly price, that is SpeakEdge.

Why do businesses look for a Retell AI alternative?

Retell AI bundles more into one price than most platforms, and it has no monthly fee. People who look elsewhere usually have one of these reasons:

The price range is wide. Retell quotes $0.07 to $0.31 a minute. Where you land depends on the model and voice you choose, so the cost of a call is hard to state until the agent is built.
Someone still has to build it. Retell gives you the parts in one place, but the agent, its prompt and its connections to your calendar or CRM are yours to configure.
Phone numbers and extras are billed separately. Its pricing page lists phone numbers at $2 a month, extra simultaneous calls at $8 each per month, and knowledge bases at $8 a month each after the first ten.

For an agency or a developer these are small things. For a business owner who wants calls answered, they add up to a project.

Retell AI alternatives compared

Platform	Price	Monthly fee	Who sets it up	Best for
Retell AI (for reference)	$0.07 to $0.31/min, depending on model and voice	None	You or your developer	Agencies and teams that want one bill
SpeakEdge	About $0.25/min on Starter (40 conversations of about 5 minutes). In India, about ₹6.7/min	$49 or $99. In India, ₹3,999 or ₹7,999	SpeakEdge, included in every plan	Businesses with no developer that want leads captured and appointments booked
Vapi	$0.05/min plus providers, about $0.08 to $0.14/min	$0, Core $29, Pro from $999	You or your developer	Developers who want to choose every part
Bland AI	$0.14/min on Start, $0.12/min on Build	$0 or $299	You or your developer	One flat rate, high call volume
Bolna	6¢/min, or ₹5.52/min	None	You or your developer	Indian languages, build it yourself
Synthflow	Not published	Contracts from $30,000 a year	Not stated on its pricing page	Large enterprise contracts

The per-minute platforms charge for usage only, and you supply the building. SpeakEdge's monthly price covers the usage and the setup, so compare the total cost of getting a working agent, not only the rate.

SpeakEdge: an AI receptionist set up for you

SpeakEdge is an AI receptionist and voice agent for businesses that do not want to build one. It answers on your website, your phone line and WhatsApp, asks the questions your sales team would ask, books the appointment, and sends you each lead with a recording, a transcript and a summary.

The Starter plan is $49 a month for one AI assistant and 40 conversations, where a conversation is about 5 minutes. The Growth plan is $99 a month for three assistants, 80 conversations, 50+ languages and two CRM integrations. Both include full onboarding and setup of the assistant, and both start with a 14-day free trial with no credit card. In India the same plans are ₹3,999 for 600 minutes and ₹7,999 for 1,200 minutes, and the agent speaks 11 Indian languages including Hindi and English.

Two limits to know. Per minute, SpeakEdge costs more in US dollars than a platform you assemble yourself, because the setup is in the price. And the Starter plan is English only; other languages start on Growth.

Pick SpeakEdge if you run a clinic, a real estate office, a school or a similar business, you have no developer, and what you want is enquiries answered and qualified at any hour. See SpeakEdge pricing.

Vapi: for developers who want every choice

Vapi charges $0.05 a minute for its platform and passes the other providers through at cost. Its pricing page lists transcription at about 1 cent a minute, the model at 1 to 5 cents and the voice at 1.5 to 2.4 cents, so a typical call lands between 8 and 14 cents a minute before any phone carrier charge. New accounts get $5 in credits. Paid support packages are $29 a month for Core and from $999 a month for Pro, and extra simultaneous calls are $10 per line per month.

Pick Vapi if you have a developer and want to pick the model, the voice and the phone carrier yourself.

Bland AI: one flat price per minute

Bland AI charges a single rate that includes the model, transcription and voice. The Start plan is $0.14 a minute with no monthly fee, limited to 100 calls a day and 10 at once. The Build plan is $299 a month plus $0.12 a minute, with 2,000 calls a day and 50 at once.

Pick Bland AI if you want to know the cost of a call before it happens, or you run large calling campaigns.

Bolna: build it yourself for Indian languages

Bolna lists pay-as-you-go at 6 cents a minute, or ₹5.52. Its bundles are $300 for 6,500 minutes and $500 for 12,000 minutes. It supports more than ten Indian languages, including Hindi, Hinglish, Tamil and Telugu, and connects to Twilio, Plivo and Vobiz for phone lines. New accounts get $5 in credits.

Pick Bolna if your callers speak Hindi or a regional language and you have someone technical to build and maintain the agent.

Synthflow: an enterprise sale

On the day we checked, Synthflow's pricing page listed only enterprise contracts starting at $30,000 a year, with no self-serve plan, free trial or per-minute rate published.

Pick Synthflow if you are a large organisation ready for an annual contract and a sales process.

When should you stay with Retell AI?

Stay with Retell AI if you or your agency build agents regularly and you like having voice, telephony and chat agents under one account with no monthly fee. Twenty simultaneous calls included is generous for most small deployments.

Look elsewhere if nobody on your team will build the agent, if you want one fixed monthly price, or if your callers mostly speak Indian languages.
