Voiceflow publishes no plan prices in 2026. Its pricing page offers a free trial for agencies and a demo for businesses, and its documentation lists four plans plus a credit table that starts at $0.005 per chat message and $0.05 per phone minute. Voiceflow fits teams that design chat and voice agents step by step. Teams that only need answers from their own content can use a simpler tool.
TL;DR
- Voiceflow is a platform for building chat and voice AI agents with playbooks, workflows, a knowledge base, and tools that call other systems.
- The public pricing page shows no dollar amounts. Plan, seat, and credit bundle prices appear inside the Voiceflow dashboard under Plans and Billing.
- The documentation names four plans: Free, Pro, Business, and Enterprise. A bill has three parts: a monthly plan fee, add-ons such as editor seats and phone numbers, and credits for usage.
- The credit table lists chat usage at $0.005 per user message and phone usage at $0.05 per minute. Model, speech-to-text, and text-to-speech costs are added on top.
- Voiceflow has a live agent handoff step for Genesys, Ujet, Kustomer, Dixa, and Zendesk, and auto top-ups keep agents running when credits reach zero.
- Botpress and Landbot are the closest builders with published prices. SiteGPT is a knowledge-trained answer layer from $39 a month billed yearly, with no flow builder and no voice channel.

What is Voiceflow?
Voiceflow is a platform for building, deploying, and measuring AI agents for chat and voice. The company describes it as an AI agent platform for customer experience teams. You build an agent in the Voiceflow editor, connect a knowledge base and tools, and publish it to a chat widget, a phone number, or your own interface through an API.
Voiceflow sits on the builder side of this category. A content-trained chatbot answers questions from your documents. A builder platform lets you script what the agent does step by step. AI agent vs chatbot explains the difference between those two levels.
How does Voiceflow work?
Voiceflow works by combining a global prompt, playbooks, workflows, and a knowledge base. The Voiceflow documentation splits the product into three stages:
- Build. You write the agent's global prompt and instructions, then add playbooks and workflows as its tools.
- Deploy. You publish the agent to the chat widget, a phone number, SMS, or a custom interface through the Conversations API.
- Measure. You review transcripts and call recordings, score conversations with evaluations, and run tests before a change goes live.
What features does Voiceflow offer?
Voiceflow offers six feature groups that matter for a buying decision: playbooks and workflows, the knowledge base, voice and phone, tools, live agent handoff, and testing.
Playbooks and workflows
Voiceflow gives you two ways to control a conversation. Playbooks are goal-based conversations where the AI model decides the next step and calls tools. Workflows handle multi-step processes with fixed steps, with or without AI.
Workflow steps include messages, cards, buttons, conditions, API calls, functions, and code. This is where Voiceflow is the stronger pick over a content-trained tool. If your agent must collect details, call an API, and branch on the result, a workflow does that job. The drag and drop chatbot builder guide compares other canvas tools.
Knowledge base
The Voiceflow knowledge base accepts seven source types, according to the data sources documentation:
Source type | What it imports |
Web pages | One or more public URLs |
Sitemap | Every page listed in a sitemap |
Docs | PDF, TXT, or DOCX files up to 10 MB |
Table | CSV or XLSX files up to 10 MB |
Plain text | Content you paste in |
Zendesk | Articles from a Zendesk knowledge base |
Shopify | Product catalogues, inventory data, and SKU information |
URL and integration sources can refresh daily, weekly, monthly, or never. The agent retrieves the most relevant content and writes a grounded answer, which is retrieval-augmented generation (RAG).
One cost detail matters here. Voiceflow's optional LLM chunking strategies use credits on every sync. A daily refresh with chunking turned on spends credits every day.
Voice and phone
Voiceflow supports inbound and outbound phone calls. The phone number documentation says Voiceflow can provision a US or Canadian number, or you can connect a number from Twilio, Vonage, or Telnyx.
One Voiceflow phone number per workspace is included with a plan. Extra numbers and a higher concurrent call limit are paid add-ons. Inbound and outbound SMS are in beta and need a Twilio number.
Tools and integrations
Voiceflow agents call other systems through tools. The documentation lists built-in tools for Zendesk, Salesforce, HubSpot, Shopify, Twilio, Airtable, Make, Gmail, and Google Sheets. API, function, and MCP tools cover anything else.
Live agent handoff
Voiceflow hands conversations to human agents through a handoff step. The live agent handoff documentation lists five supported contact center systems: Genesys, Ujet, Kustomer, Dixa, and Zendesk.
The step passes the transcript or a summary to the agent, relays messages and files in both directions, and can return the customer to the AI agent afterward. Voiceflow has no agent inbox of its own, so handoff needs one of those systems. A separate call forward step covers phone calls. AI chatbots with human handoff compares how handoff works across tools.
Testing, environments, and analytics
Voiceflow includes environments for development, staging, and production, plus A/B traffic splits between versions. Evaluations score conversations on resolution, deflection, CSAT, or a custom metric. Analytics track response times, token usage, and conversation volume.
How much does Voiceflow cost in 2026?
Voiceflow does not publish plan prices in 2026. The Voiceflow pricing page shows two tracks and no dollar amounts.
Track | What the pricing page shows | Next step offered |
For Agencies and Partners | Free trial with no credit card, usage-based billing, multi-client workspaces, white-labeling, all major model providers | Start building for clients |
For Businesses | Self-serve or fully managed implementation, voice and chat channels, analytics, team roles and permissions | Book a demo |
What plans does Voiceflow have?
Voiceflow has four plans, according to its billing documentation. The documentation says current prices for plans, add-ons, and credit bundles are shown inside Voiceflow under Plans and Billing.
Plan | Built for | What the docs say it includes |
Free | Trying Voiceflow | Limited features and a one-time credit grant that does not renew |
Pro | Individual builders | All LLM models and a higher agent limit than Free |
Business | Growing teams | LLM fallback models and priority support |
Enterprise | Large-scale workloads | Unlimited product usage, single sign-on, private cloud hosting, custom credits |
A Voiceflow bill has three parts:
- Plan fee. A monthly fee that sets your features and your monthly credit allotment.
- Add-ons. Extra editor seats, extra phone numbers, and a higher concurrent call limit. Every paid plan includes some editor seats, and viewers are free and unlimited.
- Credits. Usage charges for AI responses and phone calls. Credits are shared across every workspace in the organization.
Older reviews quote $60 and $150 monthly plans and $50 per extra editor. Voiceflow's public pages do not show those figures today. Check the Plans and Billing tab in a trial account before you budget.
What does a Voiceflow credit cost?
Voiceflow charges credits for each user message, each phone minute, and each model call. The credits pricing table lists these self-serve rates:
Item | Unit | Rate |
Chat usage | Each user message or Conversations API request | $0.005 |
Phone usage | Each minute on a call | $0.05 |
GPT-4.1 mini | 1,000 input tokens / 1,000 output tokens | $0.0005 / $0.002 |
Claude Sonnet 4.6 | 1,000 input tokens / 1,000 output tokens | $0.00375 / $0.01875 |
Deepgram speech-to-text | Each minute | $0.005 to $0.007125 |
ElevenLabs text-to-speech | 1,000 characters | $0.045 |
The table covers more than 40 models from OpenAI, Anthropic, Google, Groq, xAI, and Voiceflow. Enterprise rates sit on a separate tab.
What does Voiceflow usage cost at your volume?
The table below does the math for four volumes. It covers usage only. The plan fee and any add-ons come on top.
Two assumptions sit behind the numbers. Each chat message sends 2,000 input tokens and returns 300 output tokens. Each phone minute uses Deepgram at $0.007125 and 500 characters of ElevenLabs speech.
Scenario | Math | Usage cost |
1,000 chat messages on GPT-4.1 mini | 1,000 x ($0.005 + $0.0016) | $6.60 |
10,000 chat messages on GPT-4.1 mini | 10,000 x ($0.005 + $0.0016) | $66.00 |
10,000 chat messages on Claude Sonnet 4.6 | 10,000 x ($0.005 + $0.013125) | $181.25 |
3,000 phone minutes, before model tokens | 3,000 x ($0.05 + $0.007125 + $0.0225) | $238.88 |
A chat message costs about $0.0066 on GPT-4.1 mini and about $0.018 on Claude Sonnet 4.6. The model choice changes the bill by 2.7 times at the same volume.
A phone minute costs about $0.08 before model tokens. That is 12 times the cost of a GPT-4.1 mini chat message.
The AI chatbot pricing comparison sets these usage rates next to per-message and per-conversation plans from other vendors.
Is Voiceflow free?
Voiceflow has a Free plan. It includes limited features and a one-time credit grant that does not renew. The billing documentation says the Free plan is not suitable for production usage.
Agencies and partners also get a free trial with no credit card, according to the pricing page.
What happens when Voiceflow credits run out?
Voiceflow offers three ways to add credits: upgrade the plan, move to a larger credit bundle, or turn on auto top-ups. Auto top-ups buy more credits when the balance reaches zero, so agents keep answering mid-month.
You set the dollar amount for each top-up in the billing settings. Nothing is charged in advance, and you can turn the setting off at any time. With auto top-ups turned off, a workspace that reaches zero has no credits left to pay for AI responses.
What are Voiceflow's pros and cons?
Pros
- Chat and phone in one workspace. The same agent can answer in a web widget and on a phone number.
- Two levels of control. Playbooks let the model decide. Workflows follow fixed steps.
- Published usage rates. The credit table lists a rate for every model, speech vendor, and channel.
- Wide model choice. The credit table lists more than 40 models, and the pricing page says you can bring your own.
- Native handoff to five contact center systems. Genesys, Ujet, Kustomer, Dixa, and Zendesk are supported.
- Auto top-ups. Agents keep running when the monthly credits are used up.
- Free viewers. Only people who edit agents need a paid seat.
- Release controls. Environments, version history, tests, and A/B traffic splits are built in.
Cons
- No public plan prices. You need a trial account or a sales call to see what Pro and Business cost.
- Three-part bills are hard to forecast. Plan fee, add-ons, and credits all move separately.
- Voice costs more per interaction. A phone minute costs about 12 times a GPT-4.1 mini chat message.
- It takes time to build. G2 reviewers praise the interface and also report a steep learning curve for advanced features.
- Handoff needs a contact center system. Voiceflow has no agent inbox of its own.
- Fewer content connectors. The knowledge base lists Zendesk and Shopify as its only integration sources.
- Chunking spends credits on every sync. Frequent refreshes add to the bill.
What do users say about Voiceflow?
Voiceflow holds 4.5 out of 5 on G2 from 115 reviews. 83 of those reviews give 5 stars and 29 give 4 stars.
G2 groups review themes by how often they appear. The most common positive themes are ease of use (89 mentions), features (67), and easy integrations (46). The most common negative themes are missing features (25), usage limitations (24), and complexity (18).
Who should use Voiceflow?
Voiceflow is a good fit if you:
- Need an agent that follows multi-step processes with API calls and branching
- Answer customers by phone as well as chat
- Have designers or engineers who will build and maintain the agent
- Run a contact center on Genesys, Ujet, Kustomer, Dixa, or Zendesk
- Build agents for clients as an agency
Voiceflow is a poor fit if you:
- Want a website chatbot that answers from your help content this week
- Need to compare plan prices before a sales call
- Have no one to build and maintain playbooks and workflows
- Want one fixed monthly bill with no usage meter
What are the best Voiceflow alternatives?
The best Voiceflow alternative depends on which part of Voiceflow you need. No tool here is best overall. Each row names the case it fits.
Three criteria set the order. The first is how closely the tool matches Voiceflow's main job, which is building custom conversation logic. The second is whether prices are public. The third is how fast a small team can launch.
# | Tool | Best for | Starting price | Free option | Main trade-off |
1 | Custom flows and code with published prices | $150 a month billed annually, 250 conversations | Free plan, 100 conversations, 3 seats | The voice channel is Enterprise only | |
2 | No-code flows for web chat and WhatsApp | $45 a month, or $36 a month billed annually | Free plan, 100 chats a month, no AI chats | WhatsApp with your own number starts on Professional | |
3 | The knowledge-trained answer layer for website customer service | $59 a month, or $39 a month billed yearly | 7-day trial, card required | No flow builder, no voice channel, no free plan | |
4 | A content-trained agent that also needs voice | $40 a month on Hobby. Voice starts on Standard at $150 a month | Free plan, 50 message credits | Removing branding costs $99 a month |
Botpress comes first because it is the closest match for the reason most teams choose Voiceflow: custom logic. Landbot is second for teams that want flows without code. SiteGPT is third because it does a different job, and it only fits if that job is yours.
1. Botpress: best for custom flows and code with published prices
Botpress is a cloud platform for building AI agents with a visual Studio and custom code. It prices by conversation and includes AI usage in the plan. The Botpress AI review covers it in full.
- Pricing: Free for 100 conversations. Plus is $150 a month and Team is $750 a month, both billed annually. Extra conversations cost $65 per 100 on Plus.
- Trade-off: Conversation packs are added automatically at 95% of the quota and cannot be turned off. Voice is on the Enterprise plan only.
- Best for: Teams with a developer that want flow control and a public price list.
2. Landbot: best for no-code flows on web chat and WhatsApp
Landbot is a no-code builder for web chat and WhatsApp agents. Every plan, including Free, has a shared inbox for human takeover. The Landbot alternatives guide compares it with similar builders.
- Pricing: Free for 100 chats a month. Starter is $45 a month or $36 billed annually, with 500 chats and 100 AI chats. Professional is $110 a month or $88 billed annually, with 2,500 chats and 300 AI chats.
- Trade-off: Extra chats cost $0.05 each and extra AI chats cost $0.10 each. Removing Landbot branding starts on Professional.
- Best for: Marketing and service teams that want guided flows without code.
3. SiteGPT: best as the knowledge-trained answer layer
SiteGPT is a chatbot trained on your own content for customer service and lead generation. It does not replace Voiceflow's workflows or phone agents. It answers website questions from your pages and files with no flow to build.
- Pricing: Starter is $59 a month, or $39 a month billed yearly ($468 a year), with 4k GPT-4.1-mini messages a month and 1,000 pages. Growth is $129 a month, or $79 a month billed yearly.
- Content sources: Website URLs, uploaded files, raw text, Google Drive, Dropbox, OneDrive, Box, Notion, GitHub, and YouTube.
- Trade-off: No flow builder, no voice or phone channel, and no free plan. Chat integrations such as Slack and Crisp start on Growth. Zendesk starts on Scale. There is no Intercom or HubSpot integration.
- Best for: Teams whose customers mostly ask questions that the website and help content already answer.
4. Chatbase: best for a content-trained agent that also needs voice
Chatbase is a content-trained AI agent platform with a free tier. Its Standard plan adds a helpdesk, voice, and telephony. The Chatbase review covers plans and limits.
- Pricing: Free for 50 message credits a month. Hobby is $40 a month with 700 credits. Standard is $150 a month with 4,000 credits. Pro is $500 a month with 15,000 credits. Yearly billing takes 20% off.
- Trade-off: Removing Chatbase branding is a $99 a month add-on. Voice and telephony are not on Free or Hobby.
- Best for: Small teams that want a content-trained agent first and phone answering later.
The best no-code AI chatbot builders guide ranks more tools in this category.
The stack: which tool does which job
Voiceflow and SiteGPT are different layers of a customer service stack. Voiceflow is a builder for custom chat and phone agents. SiteGPT is the knowledge-trained answer layer for a website. Many teams need one of the two. Some need both.
Layer | Job | Tool |
Conversation design | Multi-step processes, API calls, and branching logic | Voiceflow, or Botpress |
Phone channel | Inbound and outbound calls on a real number | Voiceflow with a Voiceflow, Twilio, Vonage, or Telnyx number |
Knowledge-trained answers | Website questions answered from your pages and files, with no flow to build | |
Human desk | Live agents take over a conversation | Zendesk, Genesys, Kustomer, Dixa, or Ujet through Voiceflow's handoff step. SiteGPT escalates to your team and connects to Zendesk on Scale and above |
Choose Voiceflow alone when every conversation needs custom logic or a phone line. Choose SiteGPT alone when most questions can be answered from content you already have. SiteGPT plans have a fixed price and a message quota, such as 4k GPT-4.1-mini messages a month on Starter.
How to choose between Voiceflow and its alternatives
If you need... | Pick... | Why |
Chat and phone agents built in one place | Voiceflow | It deploys the same agent to a widget and a phone number |
Handoff to Genesys, Ujet, Kustomer, or Dixa | Voiceflow | Its handoff step supports those systems natively |
Custom flows with a public price list | Botpress | Plans and overage rates are on its pricing page |
No-code flows for WhatsApp and web chat | Landbot | Its builder and shared inbox are on every plan |
Answers from your website and files, live this week | SiteGPT | It trains on existing content with no flows to build |
A fixed monthly price | SiteGPT | Plans have set prices and message quotas |
A free plan that renews every month | Botpress, Landbot, or Chatbase | Voiceflow's free credits are a one-time grant |
A content-trained agent with phone answering | Chatbase | Voice and telephony are on its Standard plan |
Frequently asked questions

Does Voiceflow require coding?
Voiceflow does not require code for a simple agent. API, function, and code steps are available for custom logic.
Pricing and free plan
How much does Voiceflow cost?
Voiceflow does not publish plan prices. A bill combines a monthly plan fee, add-ons, and credits. The credit table lists chat usage at $0.005 per user message and phone usage at $0.05 per minute, plus model costs.
Is Voiceflow free?
Voiceflow has a Free plan with limited features and a one-time credit grant that does not renew. Agencies and partners can also start a free trial with no credit card.
What are the Voiceflow plans in 2026?
Voiceflow lists four plans in its documentation: Free, Pro, Business, and Enterprise. Their prices are shown inside the Voiceflow dashboard under Plans and Billing.
Is Voiceflow's pricing worth it for mid-market teams?
Voiceflow's pricing suits mid-market teams that will use workflows, phone agents, and contact center handoff. Usage for 10,000 chat messages on GPT-4.1 mini is about $66 before the plan fee. A team that only needs answers from its own content pays for features it will not use.
Does Voiceflow charge per editor?
Every paid Voiceflow plan includes some editor seats, and more can be bought as an add-on. Viewers are free and unlimited on all plans.
Features
Does Voiceflow support voice and phone calls?
