The best Vapi alternatives
built, bought or open source.

The best Vapi alternatives depend on why you chose Vapi. If you are building voice into a product, the nearest options are other voice AI platforms and an open-source framework you can host yourself; if you used Vapi to get a business phone answered, a finished agent saves you the build and the per-minute bill. Here are six, ranked by who they suit, with how each one charges.

Why people look for Vapi alternatives

Vapi is a developer platform for building voice AI agents, and its documentation says so in those words. Every assistant combines speech-to-text, a language model and text-to-speech, chosen from dozens of providers; squads chain several assistants together with handoffs; tools connect an assistant to your own APIs; and its platform page says every capability is reachable through a REST API, with client and server SDKs alongside the dashboard. For an engineering team putting voice inside its own product, that is a sensible shape, and plenty of teams choose it for exactly that reason.

The people searching for Vapi alternatives tend to arrive from one of two directions. Some are developers who like building voice agents but want a different set of trade-offs: minutes included in a monthly plan instead of a meter, an open-source framework they can host themselves, or one bundled rate instead of several line items. Others are businesses and agencies who used Vapi, often through a freelancer, to answer a business line and book appointments, and found they had bought a project: a prompt to maintain, tools to wire into the calendar and the CRM, providers to choose, and a bill that rises with every busy week.

The pricing model is the common thread. On its Build plan Vapi bills hosting by usage: at the time of writing, its published hosting rate starts at $0.05 a minute for calls, chat and SMS are charged per message, ten concurrent calls are included with each extra line charged by the month, and model provider costs are passed through at cost, or nothing if you bring your own API key. Call history is kept for 14 days on Build. Its Scale plan moves to an annual contract with a fixed platform fee and committed volume. None of that is unusual for infrastructure. It is simply a different thing from a fixed monthly price.

This roundup ranks six alternatives for 2026 and says who each one suits. They fall into four kinds: hosted voice platforms built much like Vapi, an open-source framework for teams that want to own the stack, enterprise platforms that bundle the rate or carry the deployment, and a finished agent that charges for the software and leaves the usage on your own accounts. Each entry says how the tool charges, which channels its own site lists, and when it is the right choice, including when that means staying with a platform rather than buying a product.

Four reasons people move off Vapi

None of these is a fault in Vapi. Each follows from its published scope and pricing, and each points towards a different kind of alternative.

Somebody has to build it, and then keep it running

Vapi puts every capability behind a REST API, with SDKs, squads, tools and a choice of providers at each layer. That is the point of a developer platform, and a dashboard gets a first assistant started. But the tools that reach your calendar and CRM, the handling of every edge case and the changes when your prices move are yours to build and maintain. A business without a developer on hand ends up paying somebody to own a project it thought it had bought as a service.

The bill has more than one meter

Hosting is billed per minute of calls and per chat or SMS message. Concurrent lines beyond the ten included on Build are charged monthly. Model provider costs are passed through at cost unless you bring your own key, and HIPAA and zero-data-retention add-ons are each priced by the month. Every line is clear on its own. Together they make next month hard to forecast for anyone without revenue per call to set against them, and the phone costs most in exactly the weeks it is busiest.

Customers do not only phone

Vapi's docs describe phone calls, voice calls embedded in web apps, text chat through its Chat API, and SMS chat. That SMS chat runs only on 10DLC-approved Twilio numbers, and the docs say the customer has to send the first message. The enquiry that arrives by email, as an Instagram DM or through the chat bubble on your website, and the follow-up text to a lead who did not pick up, belong to other systems, each with its own knowledge base and its own copy of the customer.

Some settings arrive only with a contract

The Build plan keeps call history for 14 days and includes ten concurrent calls. Custom retention, custom concurrency and volume-based per-minute pricing belong to the Scale plan, an annual contract with a fixed platform fee and committed volume. Vapi's free US numbers, up to five per account, do not support outbound calls, so outbound runs on numbers imported from Twilio. Teams that outgrow the self-serve plan without wanting a contract start comparing how other platforms package the same things.

What to look for in a Vapi alternative

Start with one question: do you want to build a voice agent, or have one that is already built? Then weigh the three things that separate the tools on this list.

01 / Shape

Built, bought or self-hosted

A hosted platform gives you the same building blocks as Vapi with different packaging. An open-source framework gives you the code and the choice of where it runs, along with the operations that come with it. A finished agent gives you a knowledge base, a dashboard and nothing to deploy. Match the shape to the person who will be maintaining it a year from now, not to the demo.

02 / Price

How the bill moves in a busy month

Per minute with provider costs passed through, per minute with everything bundled, a monthly plan with minutes included, an annual contract, or a flat software fee with usage billed to you by your own carrier and AI provider. Look at concurrency charges and number fees as well as the rate. Price your busiest month on each, with your own call volumes, rather than an average one.

03 / Reach

Where your customers actually turn up

Check the channels each tool lists on its own site: calls only, or texts, email, website chat and DMs as well. Check whether the number stays in a carrier account you hold, whether it books into your real calendar and reads your CRM, and what happens when the agent cannot help: a live transfer to a person, or the caller's details taken and passed to your inbox.

The best Vapi alternatives, ranked

Bold Agent Kit is first. After it, the list is ordered by fit for the typical Vapi buyer, a technical team building voice agents: the two hosted platforms closest to Vapi's shape, then the open-source route, then the two platforms that sell to enterprises on a bundled rate or an annual contract.

We make Bold Agent Kit, which is why it is first on this list. Every other entry is described from its own website, including when it is the better choice.

01 / Best for businesses and agencies that want a finished agent, not a build

Bold Agent Kit

Bold Agent Kit is for the Vapi user who was never building a voice product. If you, or an agency working for you, put a Vapi assistant on a business line to answer calls and book appointments, this is the same job done by an agent that is already built. You set it up in a dashboard from what you already have: your hours, prices and lead times as data points, the answers you always give as Q&A pairs, your services and policies as documents, and instructions for how it greets people, what it may offer and when it should fetch you. There is nothing to deploy, and a change of price is used from the next conversation.

On the phone it runs on your own Twilio number, with separate switches for answering and dialling. It hears and speaks in real time on your AI provider's fastest model, transcribes with Google or Deepgram, and speaks in a voice from Google, Amazon Polly or ElevenLabs, or one from your own ElevenLabs or Fish Audio key, including a voice you cloned. It offers real open slots from one of eight calendars and books the one the caller picks, and every call leaves a recording and a transcript on the contact. The same agent answers texts, email, website chat and eleven DM platforms from the same knowledge base, and runs follow-up campaigns of email, text and call steps that stop on a reply, a booking or an opt-out.

Like Vapi, it runs the AI on your own key, with sixteen providers to choose from. Unlike Vapi, there is no hosting rate per minute and no charge per concurrent line: the plan is $25 a month or $200 a year for the account, with unlimited agents. Choose a platform instead if you are shipping voice inside your own software, or if you need a live call transfer, which Bold Agent Kit cannot do. It is a finished product rather than a platform to build your own application on.

02 / Best for teams that want a Vapi-style platform with a visual builder

Retell AI

Retell AI is the closest like-for-like alternative to Vapi on this list. Its site describes an AI voice agent platform for automating phone calls, pitched at the modern contact centre, with a no-code studio where the conversation is designed on a drag-and-drop canvas, with functions, integrations, call transfers, DTMF and SMS as steps, and APIs and SDKs for developers who want programmatic control. Agents take inbound calls, run outbound campaigns through batch calling, and work on the web and over chat and SMS, with post-call analysis and quality assurance on its feature list.

Telephony is flexible. Retell sells numbers, and its docs describe connecting your own provider through elastic SIP trunking, with guides for Twilio, Telnyx and Vonage and for contact-centre platforms including Genesys Cloud, Five9 and Amazon Connect. Its pricing page shows the per-minute rate assembled from parts: its voice infrastructure, the model, the text-to-speech provider and telephony. Twenty concurrent calls are free on pay-as-you-go, while extra concurrency, Retell numbers and knowledge bases beyond ten are charged monthly, and Enterprise pricing is custom. New accounts start with $10 in free credits, and a booking feature on its site links a Cal.com account so an agent can book during the call.

When to choose it: if you like Vapi's model of building your own voice agent but want a visual canvas for the flow, call transfers and batch calling in the same product, and a pricing page that breaks each minute into its components. It suits contact centres and the agencies and teams that build for them. If your reason for leaving Vapi is paying by the minute, bear in mind that Retell is priced by the minute too.

03 / Best for teams that want voice and chat agents on a monthly plan

ElevenLabs Agents

ElevenLabs Agents is the agent platform from ElevenLabs, the voice company. Its site describes configuring, deploying and monitoring agents in more than 70 languages across voice, chat and email, with telephony, a web widget added with a single line of HTML, WhatsApp and SMS among its channels. Agents are configured without code, with system prompts, knowledge bases and workflows, testing before deployment and analytics afterwards, and developers get SDKs for web and mobile, WebSocket and REST APIs, MCP and webhooks. Native integrations named on its site include Twilio, Genesys, Zendesk and Salesforce.

The pricing is a different shape from Vapi's. Instead of a hosting rate on every minute, plans are monthly and each includes a number of agent minutes and a concurrency limit, from a free plan with 15 minutes up through Starter, Creator, Pro, Scale and Business, with Enterprise on custom terms. Minutes beyond the plan are charged per minute, text messages per message, and the language model and any telephony are billed on top based on usage. Its site says the platform is model-agnostic and that you can bring your own model.

When to choose it: if you want a no-code configuration screen and a developer API in one product, a plan with minutes included so the month starts from a known figure, or an agent where the voice itself matters, with a large voice library, custom voice cloning and many languages. It is still a platform, so as with Vapi, somebody configures the agent, connects it to your systems and keeps it current.

04 / Best for developers who want to own the voice stack

LiveKit

LiveKit is the option for Vapi users who want to stop renting the stack. Its site describes an open-source framework and developer platform for building, testing, deploying, scaling and observing agents in production. The Agents framework, published on GitHub under the Apache-2.0 licence, is available in Python and Node.js and uses plugins to mix and match speech-to-text, language model, text-to-speech and realtime providers. It works with LiveKit's telephony stack, so an agent can make and take phone calls, and its site covers phone numbers and SIP.

You can run the framework on your own infrastructure, or deploy to LiveKit Cloud, which adds managed hosting and an inference gateway for models. The Cloud's free Build plan includes a monthly allowance of agent session minutes, a small number of concurrent sessions and one free US local number, with a little inference credit to start. The Ship and Scale plans raise those allowances and charge per minute beyond them, inference is billed by the model you use, and Enterprise is on custom terms.

When to choose it: if the thing you valued about Vapi was control, and you have engineers who would rather own the code, choose every provider and decide where the agent runs. It asks more of your team than a hosted platform does, since the conversation design, the integrations and the operations are yours. For a business that only wants a phone answered, that is the wrong trade; for a product team, it can be the right one.

05 / Best for enterprises that want one bundled rate per minute

Bland AI

Bland AI calls itself an enterprise voice AI platform for phone agents, and its homepage speaks to regulated industries: healthcare, insurance, financial services and logistics. Agents are built by describing them to Norm, its builder, which its site says needs no voice AI experience, or through a REST API and CLI, and scenario test suites run before an agent goes live. Its channels are voice, SMS, iMessage and web chat with one memory across them, and its connectors include Salesforce, HubSpot, Five9, Genesys, NICE CXone, Talkdesk, Amazon Connect, Calendly and Cal.com.

It differs from Vapi in two ways that matter here. The first is the price: one per-minute rate covers the language model, speech-to-text, text-to-speech and telephony, with no token charges and no model-provider pass-throughs, and plans set concurrency, calls per day and the number of voices, with Enterprise contracted to your volume. The second is where it runs: in Bland Cloud by default, inside your own VPC on AWS, GCP or Azure, or, for Enterprise, on your own hardware, with regional deployment in the US, EU and APAC. Its docs also describe connecting your own Twilio account to bring existing numbers over.

When to choose it: if you are an enterprise automating a phone operation and would rather pay one rate per minute than assemble providers yourself, or if the agent has to run inside your own network. Bland bundles the model into the rate, so there is no separate model bill to manage; if holding your own model key matters to you, as it can on Vapi, that is the trade-off to weigh.

06 / Best for enterprises that want the deployment done with them

Synthflow

Synthflow positions itself as an enterprise voice AI platform for automated phone calls. Its site describes an end-to-end platform with in-house telephony, a visual flow designer with API-connected steps, a testing sandbox, real-time monitoring and forward-deployed engineers who help take agents into production, for sectors including BPO, healthcare, financial services, retail and telecommunications. Its channels are voice, chat, SMS and WhatsApp, and it lists more than 200 integrations, among them Salesforce, HubSpot and Zapier.

Its pricing page lists one tier, an enterprise contract, with the price scoped around call volume, concurrency, telephony setup, integrations, security needs and launch support. The contract covers Synthflow native telephony, SIP trunking or approved enterprise telephony; integrations with CRMs, calendars, contact-centre stacks, webhooks and APIs; and implementation, onboarding, testing, training, launch support and ongoing optimisation.

When to choose it: if you are leaving Vapi because your team does not want to be the one building and operating the agents, and you have the volume and the budget for an annual contract with implementation included. It is the opposite of Vapi's self-serve model, and its published pricing is enterprise contracts only, so it is not aimed at a single business line.

Before you switch

What is the best Vapi alternative?

It depends on why you are leaving. A developer who wants a similar platform with a visual flow builder, call transfers and batch calling should look at Retell AI; one who wants minutes included in a monthly plan, or many languages, at ElevenLabs Agents; one who wants to own the code, at LiveKit's open-source framework. An enterprise that wants one bundled rate or deployment in its own VPC should look at Bland AI, or Synthflow for a contract with implementation included. A business or agency that only ever wanted the phone answered and the calendar filled should choose Bold Agent Kit.

Why do people switch from Vapi?

Mostly for one of three reasons. The first is effort: Vapi is a developer platform, so the assistant, its tools, its integrations and its upkeep are a project that needs an owner. The second is the bill: hosting per minute and per message, extra concurrent lines by the month, and model costs on top unless you bring your own key. The third is reach: its channels centre on voice, and its SMS chat runs only on 10DLC Twilio numbers with the customer sending the first message, so email, website chat and DMs need other tools. Which reason applies decides which alternative fits.

How is Bold Agent Kit different from Vapi?

Vapi is a platform for building voice agents; Bold Agent Kit is an agent already built for a business. You set it up in a dashboard from a knowledge base and instructions, and it answers and places calls on your own Twilio number, replies to texts, email, website chat and eleven DM platforms, books real calendar slots and runs follow-up campaigns. It is $25 a month or $200 a year for the account, with nothing per minute from us, and both let you bring your own AI key. The full side-by-side, feature by feature, is on our Bold Agent Kit vs Vapi comparison page.

Can I move my agents from Vapi?

Not by import, but the rebuild is usually quick. Take your assistant's system prompt apart: facts such as prices, hours and lead times become data points, scripted answers become Q&A pairs, longer material becomes documents, and the rules become instructions. Save any outbound script as a call template. Then connect your Twilio account, your calendar and your CRM, and import your contacts as a CSV or as a segment from the connected CRM. A number held in your own Twilio account connects directly; if you were on a free Vapi number, start on a Twilio number here.

Is there a free Vapi alternative?

There are free ways to start, though calls always cost somebody something. LiveKit's Agents framework is open source under the Apache-2.0 licence, and LiveKit Cloud has a free Build plan with agent minutes and one US number included. ElevenLabs Agents has a free plan that includes 15 minutes. Retell AI's pay-as-you-go plan starts at $0 with $10 in free credits. Bold Agent Kit has a 7-day free trial rather than a free plan. Once you go past what is included, the model, the voice and the phone minutes are paid for by usage on all of them.

Is there a Vapi alternative that is not priced per minute?

Yes, in two ways. ElevenLabs Agents and LiveKit Cloud sell monthly plans that include a set number of minutes, although usage beyond the plan is charged per minute, and on ElevenLabs the model and telephony are billed on top. Synthflow prices by annual contract. Bold Agent Kit charges a flat $25 a month or $200 a year for the account, with no per-minute, per-message or per-line charge from us. The minutes are billed by Twilio at its rates and the model by your AI provider at theirs, both on accounts you hold.

Which Vapi alternative is open source?

LiveKit. Its Agents framework is published on GitHub under the Apache-2.0 licence, in Python and Node.js, with plugins for mixing speech-to-text, language model, text-to-speech and realtime providers, and it works with LiveKit's telephony stack to make and take phone calls. You can run it on your own infrastructure or deploy it to LiveKit Cloud. Of the others, Bland AI offers deployment inside your own VPC or, on Enterprise, on your own hardware. Bold Agent Kit is hosted software, but its model can be one you host yourself, on Ollama, vLLM or any OpenAI-compatible endpoint of your own.

Can I keep bringing my own AI keys after Vapi?

On several of these, yes. Bold Agent Kit runs every agent on your own key with one of sixteen providers, including a model you host yourself, and voices can run on your own ElevenLabs or Fish Audio key and transcription on your own Deepgram key, with nothing marked up. ElevenLabs Agents says on its site that you can bring your own model. LiveKit lets you choose each provider through plugins. Bland AI works the other way: its single per-minute rate includes the model, speech and telephony, with no token charges and no model-provider pass-throughs.
