The best Voiceflow alternatives
Ranked by who is doing the build.

The best Voiceflow alternatives depend on who will build and maintain the agent. This list ranks six options, from platforms for CX and engineering teams to a finished agent a business owner can brief in an afternoon, with how each one charges and who it suits.

Why teams go looking for a Voiceflow alternative

Voiceflow describes itself as an enterprise conversational AI platform, "the AI agent platform that helps CX teams own every customer interaction, from resolution to ROI". Its site speaks to product teams who own the production experience, CX and support leaders who tune business logic, engineers who connect agents to the rest of the stack through APIs, and enterprise teams. It gives them an Agent Builder that balances agentic playbooks with deterministic workflows, a knowledge base, Functions, API blocks and custom code, environments that take an agent from development to staging to production, and an observability suite with LLM-powered evaluations. One agent can run across web, app, WhatsApp, SMS and voice.

That is a deep toolkit, and the search for Voiceflow alternatives usually starts with a mismatch between the toolkit and the buyer. The owner of a clinic, a sales team of three, or an agency running agents for a dozen local clients may want an agent answering customers this week, not a build project with a canvas to learn. Some want to see a price before a sales call: Voiceflow's pricing page asks businesses to book a demo or request pricing, and its billing documentation describes a monthly plan fee, add-ons such as editor seats and phone numbers, and credits consumed as agents generate responses and make calls. Others want outbound follow-up and calendar booking in the box rather than designed.

Plenty of people looking for an alternative are happy with the idea of building and simply want a different shape of platform: one with a helpdesk included, one priced per outcome inside a support operation, one built for voice agents from the telephony up, one lighter and faster to start, or one aimed at agents across the whole company rather than customer conversations alone. Each of those exists, each is on this list, and each is described from its own website, including when it is the better choice.

Bold Agent Kit, which we make, sits at the other end from Voiceflow. It is a finished agent rather than a platform: you brief it with your documents, Q&A pairs, prices and written instructions, connect email, texts, phone calls, website chat and eleven DM platforms, and it answers, books and follows up from that material, for $25 a month on your own AI key. If what you need is what Voiceflow is built for, a platform for a team that designs conversations for a living, the honest answer may be to stay, and the sections below say so where it applies.

Four reasons people move on from Voiceflow

None of these is a fault in Voiceflow. Each follows from its published scope and pricing model, and each matters more to some buyers than to others.

Somebody has to build it

Voiceflow's platform overview describes building an agent from a knowledge base, multi-step tasks in the Workflow Builder, Functions and API blocks for third-party services, and custom code, then launching it through the web chat UI or any custom interface through the Dialog API. For a product team with a conversation designer and an engineer, that is the point. For a business whose owner answers the phone between jobs, it is a project nobody has time to start, and a system nobody on the team can change once the builder has moved on.

The price is behind a demo

At the time of writing, Voiceflow's pricing page publishes no plan prices. Agencies and partners can start a free trial with usage-based billing; businesses are asked to book a demo or request pricing. That suits an enterprise buying cycle with procurement and a pilot. A buyer comparing three tools on a Tuesday evening, who wants to know what next month will cost before speaking to anyone, often moves on to a vendor whose price is on the page.

AI usage is metered in credits

Voiceflow's billing documentation says agents consume credits when they generate AI responses and make phone calls, from a monthly allotment that resets each billing cycle, with a higher plan, a credit bundle or automatic top-ups when credits run low. Editor seats and extra phone numbers are add-ons. That is a reasonable way to price a platform. It also means the bill follows the traffic, and some businesses would rather hold the key with the model provider themselves and pay that provider directly.

The native list is an enterprise list

Voiceflow's native integrations are Zendesk, Salesforce, HubSpot, Shopify, Airtable, Google Sheets, Gmail and Twilio, and anything beyond them is reached through a REST API, a custom Function or the Model Context Protocol. For a team with engineers, anything with an API is within reach. For a roofer on ServiceTitan, a cleaner on Jobber or an agency on GoHighLevel without an engineer, a connection somebody has to write is the difference between a booking in the diary and a link in a message.

What to look for in a Voiceflow alternative

Most Voiceflow alternatives differ on three things. Decide where you stand on each before you compare feature lists, because the lists are long and these three decisions are what separate the tools.

01 / Build

Who builds it, and who keeps it working

A platform gives you control and asks for builders: a canvas or code, workflows to maintain, and somebody who understands them when a price or a policy changes. A finished agent gives you less to control and less to maintain: material and instructions, changed in a sentence. Be honest about who on your team will own the agent in six months, and choose the kind of tool that person can actually work in.

02 / Reach

The channels your customers already use

List where your customers actually start conversations: the website, the phone, WhatsApp, Instagram, email, texts, perhaps Telegram or LINE. Then check what each tool lists as a channel, what it costs to add one, and whether one agent with one knowledge base answers all of them. An agent that only covers the website leaves the DM and the voicemail to somebody else.

03 / Cost

A bill you can predict before the busy month

The alternatives here charge by credits, conversations, outcomes, minutes, Actions or a flat fee, and some pass model costs through while others include them. None of those is wrong, but each behaves differently in a month with three times the traffic. Work out what a busy month costs on each, and whether you can bring your own AI key so the model is billed to you at cost.

The best Voiceflow alternatives, ranked

Bold Agent Kit is first because we make it, and because it suits the buyer who finds Voiceflow more platform than they need. The rest are ordered by how closely they fit the typical Voiceflow buyer, a CX or product team that wants to design and control its own agent: Botpress, the nearest like-for-like platform; Intercom Fin, for support teams that would rather configure than build; Vapi, for engineering teams whose agent lives on the phone; Chatbase, a lighter no-code option; and Relevance AI, for enterprises building agents beyond customer service.

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 small teams and agencies that want a finished agent on every channel

Bold Agent Kit

Bold Agent Kit is one AI agent for the conversations a business actually has: email, texts, phone calls, website chat and DMs on Messenger, Instagram, WhatsApp, Telegram, LINE, Viber, Slack, Discord, Bluesky, Reddit and X. There is no canvas. You name the agent, choose a model and paste your own API key, then give it your documents as PDF or Word, Q&A pairs for the questions you get every day, your prices, hours and lead times as data points, and the pages of your own site it may link to. You write its instructions in plain sentences: how it talks, what it offers and when it should stop and fetch you.

From then on it answers genuine incoming messages on every channel you switch on, from that material and nothing else, and stores every reply beside the source it came from. It offers real open slots from your calendar and books the one the customer picks. It runs follow-up campaigns of email, text and call steps, each with its own delay and send condition, inside the days and hours you allow, stopped by a reply, a booking or an opt-out on any channel. Every conversation lands in one inbox, where you can reply yourself and the agent stands down.

Choose it if you run a small business, a sales team or an agency and want an agent live this afternoon rather than a platform to build on. It is $25 a month or $200 a year for the whole account, with unlimited agents, a 7-day free trial and the AI on your own key with one of sixteen providers, billed by them at cost. Choose Voiceflow, or one of the platforms below, if you need an agent inside your own app, or a design team working through development, staging and production.

02 / Best for support teams that want an agent builder and a helpdesk in one

Botpress

Botpress calls itself an AI-native customer support platform, and "an AI agent company that built a helpdesk". It offers several ways to build: Botpress Studio, a visual AI agent builder; Botpress Viber, which builds, tests and publishes an agent from a plain-language description with no nodes or flows; and Built by Botpress, where its own team builds and maintains custom agents. Knowledge bases, tables and escalation rules sit underneath, and Botpress Desk is a full helpdesk with teams, routing, macros and a help centre, which can also run on top of an existing Zendesk or Intercom.

Its site says its agents are built to take action, such as processing refunds, updating accounts and running multi-step workflows, and its Desk page lists webchat, email, WhatsApp, Slack, Discord, Telegram, Instagram, Facebook Messenger and voice as channels. Pricing is per conversation, with AI usage included: at the time of writing there is a free plan with 100 conversations, and its published paid plans start at $150 a month, billed annually, for 250 conversations and three seats. Its pricing table shows the voice channel on the Enterprise plan.

Choose Botpress if you like the idea of a builder like Voiceflow but want the helpdesk in the same product, or would rather describe the agent in plain language than draw it. It suits support teams whose tickets need real actions in their own systems.

03 / Best for support teams already running a help desk at volume

Intercom Fin

Fin is Intercom's AI agent for customer service. It can run inside Intercom's own help desk, which adds an inbox, ticketing, a help centre, a knowledge hub, workflows and reporting, or on top of another help desk such as Salesforce or HubSpot. Fin's site describes it working across chat, email, voice, Slack and social, taking actions in other systems through APIs, data connectors or MCP, following Procedures you configure, and handing off to your human team with the conversation's context.

It is priced by outcome. At the time of writing, its pricing page lists $0.99 per outcome, counted once per conversation, where an outcome is a resolution, a Procedure handoff or a disqualification, with qualifications at $9.99; a conversation passed to your team without an outcome is not charged. Intercom's own plans add seat prices for teammates, and there is a 14-day free trial. Fin Voice is offered on custom pricing to select customers through sales.

Choose Fin if you are a support team with a help desk and a steady ticket volume, and you would rather configure an agent's tone, knowledge and behaviour yourself than design one from nodes. Its site says that configuration needs no engineering resources, which is the trade a Voiceflow team makes by moving to it: less to build, in a product shaped around a support operation.

04 / Best for engineering teams building voice agents into their own product

Vapi

Vapi is a platform for building voice agents, and its site talks to teams who ship software: "build, deploy, and improve voice agents as fast as you ship". You configure everything from the voice and the conversation flow to the telephony and the integrations, and Vapi handles the infrastructure, with orchestration and real-time monitoring of every call. An Enterprise tier adds contractual uptime, a dedicated deployment engineer and access controls.

Pricing is usage-based. At the time of writing, its pricing page lists $0.05 a minute for Vapi hosting on calls and $0.005 a message for SMS and chat, with model provider costs for speech, language and voice passed on at cost, or nothing from Vapi if you bring your own API key. Ten concurrent calls are included, with extra lines at $10 a month each, and the Enterprise plan adds a fixed platform fee and committed volume.

Choose Vapi if your agent lives on the phone and you have engineers who want to control every layer of it, from the speech model to the telephony. Like Voiceflow, it is a platform rather than a finished product, so somebody on your side does the building.

05 / Best for a no-code support agent trained on your own content

Chatbase

Chatbase is a platform for AI agents in customer experience, working across chat, email and voice. You connect your data sources, define the agent's role and set guardrails without code, test it against real customer scenarios, then publish it to your website, WhatsApp, email, Slack and Meta's apps. Its actions are written in plain language and followed step by step, a help desk and voice arrive on its Standard plan, and its analytics report on topics, sentiment and trends.

It is priced in message credits. At the time of writing, there is a free plan with 50 message credits a month, on which agents are deleted after 14 days of inactivity, and its published paid plans start at $40 a month with 700 credits, with Standard at $150 for 4,000 and Pro at $500 for 15,000. Paid plans come with a 7-day trial, and extra agents, branding removal and auto-recharge credits are sold as add-ons.

Choose Chatbase if you want a support or sales agent trained on your own content and live quickly, without a builder canvas, and you are happy to buy capacity in credits. It is a lighter step than Voiceflow for a team that mostly needs answers from its documents.

06 / Best for enterprises building agents across departments

Relevance AI

Relevance AI builds specialist AI agents for enterprise teams, "built and customized by your team". Its site shows agents triggered by events, connected to your apps, coordinated into teams and evaluated on live runs, with a no-code agent builder and a shared context layer that holds tone of voice and business knowledge once for every agent. An embedded deployment team maps the first use cases and builds the first agents with you, then trains your people to build more.

Its examples lean towards revenue and operations work: enriching accounts in the CRM, preparing briefs before calls, logging notes and follow-ups, booking qualified meetings and drafting proposals. At the time of writing, its pricing page presents an Enterprise plan arranged through sales, with custom Actions and Vendor Credits, unlimited agents and users, more than 2,000 integrations, and calling and meeting agents.

Choose Relevance AI if your interest in Voiceflow was really about putting agents to work across the company, not only in customer conversations, and you want a vendor to help deploy them. It is bought through a sales conversation, as Voiceflow's business plans are.

Voiceflow itself publishes no plan prices for businesses at the time of writing; its billing documentation describes a monthly plan fee, add-ons such as editor seats and phone numbers, and credits consumed as agents generate responses and make calls. Bold Agent Kit is $25 a month or $200 a year for the whole account, with the AI on your own key and texts and calls billed by your own carrier, so a busy month costs no more from us than a quiet one.

We checked each tool’s public website on 11 September 2026 for this page. Plans and features change, so check each vendor’s own site for the current detail. Product names are trademarks of their owners, and Bold Agent Kit is not affiliated with or endorsed by any of them.

Which Voiceflow alternative is right for you

If you chose Voiceflow because you want to design and own every detail of an agent, with engineers wiring it into your systems, stay on a platform. Botpress is the closest like-for-like choice and adds its own helpdesk; Vapi is the choice when the agent lives on the phone; Relevance AI suits an enterprise building agents across departments. If you run a support operation and would rather configure than build, Intercom Fin is shaped around exactly that, priced per outcome.

If you came to Voiceflow wanting an agent on your website and found a platform, the answer is a finished product. Chatbase gets an agent trained on your documents live on credits. Bold Agent Kit goes further for small businesses, sales teams and agencies: one agent on email, texts, calls, website chat and eleven DM platforms, follow-up campaigns, real calendar bookings and one inbox, for $25 a month on your own AI key.

The simplest test is who will maintain the agent in six months. If that is a conversation designer, a builder earns its keep. If it is the owner, it should be a knowledge base and a paragraph of instructions.

Before you switch

What is the best Voiceflow alternative?

It depends on who is building. For a CX or product team that wants a platform to design on, Botpress is the closest match and adds its own helpdesk. For a support team that would rather configure an agent inside a help desk, Intercom Fin fits, priced per outcome. For engineers building phone agents, Vapi. For a quick agent trained on your documents, Chatbase. For an enterprise putting agents to work across departments, Relevance AI. For a small business, sales team or agency that wants one finished agent on email, texts, calls, website chat and eleven DM platforms, Bold Agent Kit, at $25 a month on your own AI key.

Why do people switch from Voiceflow?

Mostly because of fit rather than fault. Voiceflow is built for teams that design conversations, with an Agent Builder, a Workflow Builder, Functions, API blocks and staging environments, and a small team may not have the people to use all of that. Its pricing page asks businesses to book a demo or request pricing rather than publishing plan prices, and its billing documentation describes a plan fee, add-ons for editor seats and phone numbers, and credits consumed as agents respond and call. Buyers who want a published price, a finished agent, or outbound follow-up in the box tend to look elsewhere.

How is Bold Agent Kit different from Voiceflow?

Voiceflow is a platform on which a team designs an agent; Bold Agent Kit is an agent you brief. You give it documents, Q&A pairs, data points, the pages it may link to and written instructions, and it answers on email, texts, phone calls, website chat and eleven DM platforms from that material. It also runs follow-up campaigns, books real calendar slots and puts every conversation in one inbox. It is $25 a month or $200 a year on your own AI key. The full side-by-side, feature by feature, is on our Bold Agent Kit vs Voiceflow comparison page.

How do I move from Voiceflow to Bold Agent Kit?

Start from the content, not the flows. The documents and FAQs behind your Voiceflow knowledge base go into the agent as PDF or Word files and Q&A pairs; prices, hours and lead times become data points; and the logic in your workflows becomes plain instructions about what to offer and when to hand over. Then connect the channels, add the chat snippet to your site, and switch auto-reply on for one channel at a time. Nothing is sent on its own until you switch a channel on or start a campaign, so you can check its answers in the inbox before you move your traffic across.

Is there a free Voiceflow alternative?

Some alternatives publish free plans. At the time of writing, Botpress has a free plan with 100 conversations, three seats and three AI agents, and Chatbase has one with 50 message credits a month, on which agents are deleted after 14 days of inactivity. Voiceflow's own documentation describes its Free plan as a one-time credit grant that does not renew and is not suited to production use. Bold Agent Kit has no free plan: it has a 7-day free trial, then costs $25 a month or $200 a year for the whole account, with the AI on your own key.

Does Bold Agent Kit have a visual flow builder like Voiceflow?

No, and that is deliberate. There is no canvas, no nodes and no workflow to draw. An agent is configured with a knowledge base, your documents, Q&A pairs, data points and the pages of your own site, plus written instructions on tone, offers and when to fetch you. Outbound work is a campaign: a sequence of email, text and call steps, each with its own delay and send condition, run inside a schedule you set and stopped by a reply, a booking or an opt-out. If you need a flow you can see and edit node by node, a builder such as Voiceflow or Botpress suits you better.

Can a Voiceflow alternative answer phone calls?

Several can. Vapi is built for voice agents, with calls priced by the minute. Botpress lists voice among its channels and shows it on its Enterprise plan. Intercom offers Fin Voice on custom pricing through sales, and Chatbase lists voice on its Standard plan and above. Bold Agent Kit answers and places calls on your own Twilio number, with separate switches for answering and dialling, hears and speaks in real time, and keeps the recording and transcript in the same inbox as your email, chat and DMs. You pay Twilio for the minutes; there is no per-minute charge from us.

How do Voiceflow alternatives charge for the AI?

In several different ways. Voiceflow's documentation describes credits consumed as agents respond and call. Botpress includes AI usage in a per-conversation price. Intercom charges $0.99 per Fin outcome at the time of writing, Chatbase sells message credits by plan, Vapi passes model costs through at cost or lets you bring your own key, and Relevance AI uses Actions and Vendor Credits. Bold Agent Kit always runs on your own key with one of sixteen providers, billed to you by that provider at cost, with no markup, metering or credit packs, so a busy month costs no more from us.
