What Are the Best Voiceflow Alternatives in 2026? 8 Chat and Voice Platforms, Priced

The best Voiceflow alternative for phone support is ElevenLabs Agents or Vapi on price (about $812, and $819 to $1,290, for 10,000 call minutes) or Retell AI on reviews ($1,144 for the same month); for website chat, Botpress is the closest builder at $709 for 1,000 chats and Chatbase the simplest at $150. Synthflow is the managed option, from $30,000 a year, and Copilot Studio fits Microsoft 365 companies.

Which Voiceflow alternative fits your use case?

Why do teams look past Voiceflow?

Voiceflow has few public complaints. Its Trustpilot page shows 4.1 from 15 reviews, 13 of them five-star, and Product Hunt shows 4.6 from 5; G2 shows 4.6 from 113, all checked September 19, 2026. G2's review pages didn't load in our browser that day, so we quote none of them. The two one-star Trustpilot reviews are about support: Alfredo, in the US, wrote "Terrible Support when launching the Agent" (April 7, 2026), and Brandon Parkash, in the UK, said Voiceflow made it "difficult to contact them" about technical issues (March 5, 2025). The reasons to leave are mostly structural, and they're on Voiceflow's own pages.

1. The prices are inside the product. Voiceflow's public pricing page shows no numbers. In a free account, the plans screen lists Pro at $60 a month and Business at $150, each fee returned as usage credit, and the credits pricing table meters half a cent per customer message, model tokens, and $0.05 per phone minute. You can't compare Voiceflow with a rival without signing up first.

2. Support features sit on Enterprise. The in-app plan table marks human chat hand-off, SMS, SSO, HIPAA and PII redaction as Enterprise-only. Vendr's buyer data puts the median Voiceflow contract at $258,625 a year. A support team that needs a human handoff on chat is pricing an Enterprise deal, not the $150 plan.

3. Voice capacity on self-serve plans is small. Pro includes 5 concurrent calls and one phone number, Business 15 concurrent calls; extra numbers are $5 a month and extra concurrent calls $10 a month each. A queue that takes 20 calls at once needs Business plus five add-on lines before a single minute is billed.

4. The bill moves with the model. In a test conversation in our own Voiceflow account on September 19, 2026, one reply on the default Core 4.2 model cost $0.0072 and called our order-lookup tool in 205 ms. The same reply on a frontier model costs several times more, because every turn is metered in tokens. That's fair pricing, but it means a support lead has to watch a model dropdown to forecast spend.

For balance: most of Voiceflow's reviewers are builders who like it. Gaurav Daryanani, in India, called it the "Easiest platform to create a chat agent" on Trustpilot (October 29, 2025).

What does each alternative cost for the same month?

We priced two months, because Voiceflow sells both. The voice month is 10,000 inbound minutes, about 3,300 three-minute calls. The chat month is 1,000 support conversations with four customer messages and four AI replies each. Every row is the cheapest combination the vendor lets you buy, on its published rates as of September 19, 2026.

The voice rows cluster between about $800 and $1,500 because they buy the same parts (speech-to-text, a model, text-to-speech, a phone line) and the platforms differ mostly in margin and in what they bundle. Retell and Bland bill you one figure per minute; Vapi and Voiceflow pass the parts through and let you pick them. Every per-minute vendor earns more from longer calls, whether or not the call solves anything. None of the voice platforms here charges less when the agent resolves the call.

What are the eight Voiceflow alternatives?

Retell AI

Retell AI is the most-reviewed voice agent platform here: 4.9 from 814 reviews on Trustpilot and 4.8 from 2,638 on G2. It's pay as you go at $0.07 to $0.31 a minute for voice, depending on the model, voice and telephony you pick, and from $0.0005 per AI message for chat on its cheapest model (GPT 5 nano, in the model table; the headline card says "$0.002+"), with $10 of free credit and 20 concurrent calls before extra lines cost $8 each.

A support stack on GPT 5.4 mini with Retell's voice and telephony works out to $0.114 a minute, so 10,000 minutes and two phone numbers cost $1,144. It answers complaint 3 directly: 20 concurrent calls come free, against Voiceflow Pro's 5. The watch-out is that the $0.07 floor is only the voice infrastructure; model and telephony are separate lines, and Retell's docs say long prompts scale the billed duration. Choose Retell if phone calls are the main channel and you want a platform with a large review base.

Vapi

Vapi is the developer's option: $0.05 a minute for hosting, with the transcriber, model and voice billed at the provider's cost. Its pricing calculator puts 10,000 minutes at $819 to $1,290 on its default stack of Deepgram, OpenAI and ElevenLabs. The usage-only tier includes $5 of credit, 4 concurrent calls and one number; Core is $29 a month for 10 lines, and Pro has a $999 minimum.

Vapi also sells through AWS Marketplace at $0.05 a minute, and Vendr's buyer data shows a median contract of $105,000 a year. It fits teams that want to swap models and voices and write code. The watch-outs: HIPAA is a $2,000-a-month add-on, the free numbers are US-only and inbound-only, and reviews are thin and weak, with 2.4 from 15 on Trustpilot. Choose Vapi if you have engineers and want control of every component.

ElevenLabs Agents

ElevenLabs Agents comes from the voice company, which now brands it ElevenAgents, and its pricing is plan minutes with a flat overage: Pro is $99 a month for 1,238 minutes and 20 concurrent calls, and each extra minute is $0.08, with the language model billed per minute on top (Gemini 2.5 Flash was $0.0012 on September 19; the pricing page now says model fees show inside the platform). Going over your concurrency limit bills burst minutes at double rate, $0.16. Telephony is billed separately.

Our 10,000 minutes come to $99 + 8,762 × $0.08 = about $800, plus about $12 of model time, which beats the $990 Business plan. That's the lowest published voice figure here, and the voices are ElevenLabs' own. The watch-out is the parts it leaves out: phone lines come from your own provider, and the Trustpilot score of 3.0 from 1,150 covers all of ElevenLabs, mostly its speech products. Choose it if voice quality leads the decision and you can wire in telephony.

Bland

Bland prices by plan and minute: Start is $0 a month plus $0.14 a minute (100 calls a day, 10 concurrent), and Build is $299 plus $0.12 (2,000 calls a day, 50 concurrent). Its billing docs also list a Scale plan at $499 plus $0.11 that isn't listed on the pricing page. Transfers cost $0.05 a minute on Start and $0.04 on Build, and the web widget is $0.01 per agent message.

At 10,000 minutes in three-minute calls you'd make about 111 calls a day, over Start's cap, so the month is $299 + $1,200 = $1,499 on Build. Bland is built for volume and outbound campaigns, with its own infrastructure. The watch-outs: its pricing page and docs describe telephony charges differently, there's a minimum charge per outbound attempt, and we couldn't read its G2 page. Choose Bland if you run outbound calling at scale.

Synthflow

Synthflow no longer sells a self-serve plan. Its pricing page says "Enterprise contracts start at $30,000 annually", scoped around call volume, concurrency and telephony, and its docs describe the older Pro and Growth plans as closed to new subscriptions.

That's $2,500 a month before you've placed a call, the highest floor here, and in return Synthflow scopes and launches the agent with you. Its last self-published rate, in an August 2025 blog post, was $0.08 a minute. Trustpilot shows 4.1 from 215 reviews. Choose Synthflow if you'd rather buy a managed phone agent than build one; skip it for a pilot.

Botpress

Botpress is the chat-side match for Voiceflow's builder: a visual studio with code where you need it and many messaging channels. It bills per conversation, from $189 a month billed monthly for 250 (or $150 billed annually), with packs of 100 at $65, so our 1,000-chat month is $709 on the monthly plan. For voice, its pricing FAQ counts three minutes of a call as one conversation, but the voice channel is an Enterprise feature.

Per-conversation billing is the opposite of Voiceflow's metering: an eight-turn chat on a heavy model costs the same as a two-turn one. At small volume it's much more expensive ($709 against $60 for our chat month), and the gap narrows on Team, where packs are $50 per 100. G2 shows 4.5 from 512 reviews. Choose Botpress if your agent is chat-first and you want a fixed cost per conversation. Our Botpress alternatives list covers the reverse move.

Microsoft Copilot Studio

Copilot Studio covers chat and voice on one meter. Microsoft's billing rates charge 2 credits per generative answer, 10 credits a minute for Classic voice and 35 for GenAI Voice; credits cost $0.01 each pay-as-you-go or $200 per pack of 25,000.

Our chat month is 8,000 credits, or $80. The voice month is 100,000 credits on Classic voice (4 packs, $800) or 350,000 on GenAI Voice (14 packs, $2,800). The watch-outs: the credit meter takes work to forecast, and on prepaid capacity agents stop at 125% of what you bought. Gartner Peer Insights shows 4.3 from 89 ratings. Choose it if your IT already runs Microsoft 365 and Azure, which an agent needs.

Chatbase

Chatbase is the least-setup option for chat: point it at your content, write instructions, embed the widget. Standard at $150 a month includes 4,000 message credits, and on its 1-credit Auto model that covers our 1,000-chat month. A phone channel, in beta, connects through your own Twilio account or a SIP trunk.

Voice minutes draw on the same credit pool, but Chatbase publishes no per-minute rate, so we can't price the voice month. It bills per reply weighted by model, like Voiceflow's token meter, so a premium model raises the bill. Trustpilot shows 3.9 from 65, with one-star reviews focused on billing and support. Choose Chatbase if a website chat agent is the whole job and you don't want to design flows.

Who should stay on Voiceflow?

Stay if you're building agents for clients or for several products, since Voiceflow's workspaces, projects and version history suit that work, and its Pro fee returns as credit, so a small agent costs $60 a month. Stay if you use both chat and voice from one design, which none of the voice-first platforms above does as well. And stay if your chat volume is low: at 1,000 chats our model puts Voiceflow at $60, below every chat row except Retell's per-message floor and Bland's widget.

Leave when you need Enterprise-only features on a mid-market budget (chat handoff, HIPAA, SSO), or when phone volume needs more concurrency than Pro or Business includes.

What moves when you switch from Voiceflow?

Designs and flows. Voiceflow's API has an export environment call that serializes the agent, playbooks, tools and knowledge base into one document. It's meant for archiving or moving to another Voiceflow project; none of the platforms here imports it. Rebuild the flows and use the export as the spec.

Knowledge. Re-upload your knowledge base documents and URLs on the new platform.

Prompts and tools. Copy prompts and API tool definitions (URL, method, inputs) by hand. Retest them on the new platform's models, since answers change with the model.

Phone numbers. Voiceflow's phone docs let you use a number Voiceflow provisions (US or Canada) or connect your own from Twilio, Vonage or Telnyx. Numbers in your own Twilio, Vonage or Telnyx account stay yours to point at the new platform; a Voiceflow-provisioned number needs a conversation with Voiceflow before you cancel.

Transcripts. Export any transcripts you need before canceling; none of the platforms here imports another's history.

Where does Macha fit?

Macha isn't a voice or chat agent builder, so it isn't one of the eight. It's an AI agent layer that works inside the help desk your team already uses, on Zendesk, Freshdesk, Gorgias, Front, HubSpot or Intercom. If your Voiceflow agent's real job is resolving support tickets, Macha's agents act inside those tickets, and the Macha team builds, tests and monitors them on every plan. Pricing is per ticket: one thread with one person is one charge however many replies it takes, from $299 a month for 750 tickets (about $0.40 a ticket). It's the wrong fit for an outbound calling campaign or a website agent with no help desk behind it. See Macha's pricing and our overview of AI agents for customer service.

How we researched this

On September 19, 2026 we checked the pricing page of every platform here in a browser and saved a screenshot of each, and read Voiceflow's reviews on Trustpilot and Product Hunt. G2's Voiceflow pages loaded blank for us, so we use its score from a read earlier that day and quote no G2 reviews; Reddit didn't load. The Voiceflow run log and plan table come from our own free Voiceflow account, where we ran a two-turn test chat with one API tool the same day. We made no phone calls on any platform and created no new vendor accounts, so every voice figure is built from published rates, and the Voiceflow minute cost is our estimate from its rate card. Retell, Vapi, Bland, Synthflow and ElevenLabs figures are the ones we use across our voice platform research, rechecked against their pricing pages that day.

Frequently asked questions

What is the best alternative to Voiceflow? For phone support, Retell AI has the largest review base and published per-minute rates; ElevenLabs Agents and Vapi are cheaper at 10,000 minutes. For chat, Botpress is the closest builder and Chatbase the simplest. For Microsoft shops, Copilot Studio.

Is Voiceflow worth it? It is for agencies and builders who design several agents and keep volumes modest: Pro is $60 a month and the fee comes back as usage credit, so our 1,000-chat month costs $60. It's worth less if you need human chat handoff, SSO or HIPAA, which are Enterprise features, or high call concurrency.

Can I use Voiceflow for free? Yes, to build and test. The Free plan has one editor and a one-time $1 of usage credit, according to its billing docs. It isn't meant for production traffic.

Is there a free Voiceflow alternative? Retell gives $10 of credit and Vapi $5, ElevenLabs' free plan includes 15 minutes of calls, Bland's Start plan has no platform fee, and Botpress's free plan covers 25 conversations. None covers a production month.

Which AI voice agent platform is best for customer support? For inbound support, compare Retell AI ($1,144 for 10,000 minutes with two numbers, 20 free concurrent calls) and ElevenLabs Agents (about $812 plus telephony). If you want a vendor to build it for you, Synthflow's enterprise contracts start at $30,000 a year.

Voiceflow vs Botpress: which is cheaper? For 1,000 chats a month, Voiceflow on its default model costs about $60 and Botpress $709 in our model. Botpress's fixed price per conversation catches up at higher volumes and on long conversations, and Botpress voice is Enterprise-only.

What is the best conversational AI platform? It depends on the channel and the team. Our guide to conversational AI platforms compares the market by type, from voice APIs to enterprise contact-center suites.

If your support already runs through a help desk and your agent's job is closing tickets, start with $50 of free Macha usage, no card needed.
