Voiceflow alternatives: free, open-source, chat and voice options compared

Voiceflow has moved toward enterprise customer experience teams, and its pricing page now asks businesses to request a quote. If you are a smaller team, an agency or a business owner, this guide splits the alternatives by what you are building, chat or voice, and gives prices you can actually see.

Why is Voiceflow's price no longer on its pricing page?

Because Voiceflow now sells mainly to customer experience teams. When we checked in October 2026, its pricing page showed two offers with no plan prices: one for agencies and partners, with a free trial and usage-based billing, and one for businesses, with "Request pricing" and a demo.

What each offer listed:

Voiceflow's home page describes it as an AI agent platform for CX teams, supporting customers across web, app, WhatsApp, SMS and voice. That is a capable product, with strong design collaboration and analytics. But for a small team that wants to know the monthly cost before a sales call, it has become harder to evaluate. That, more than features, is why people search for alternatives. Our earlier ReplyKit vs Voiceflow page covers the head-to-head.

If you still want to evaluate Voiceflow, go into the sales call with these questions written down:

• What is the minimum annual commitment, and is there a monthly option?
• What is the usage unit (credits, conversations, minutes), and what does one cost above the allowance?
• Are AI model costs included, or passed through from the provider?
• Which channels are included, and does WhatsApp need a separate provider and Meta's fees?
• Who builds the first agent: your team, Voiceflow, or a partner, and at what cost?

The same questions work for any vendor that quotes privately. Compare the answers with the published prices below.

Chat-first or voice-first: pick your branch before you pick a tool

Voiceflow did both chat and voice, which is why alternatives lists often mix tools that do very different jobs. Decide which you need first.

Voiceflow alternatives for chat agents

Prices checked on each vendor's own page in October 2026. We make ReplyKit, so weigh our view accordingly.

Botpress

Best for: builders who liked Voiceflow's control. Free for 100 conversations a month; Plus is $150 a month billed yearly for 250 conversations and $25 of AI usage; Team is $750. Pros: flexible logic and many integrations, transparent pricing. Cons: needs technical skill. See Botpress alternatives.

Landbot

Best for: visual, structured flows such as lead forms. Free for 100 chats; Starter EUR 40 a month (EUR 32 yearly) with 100 AI chats; your own WhatsApp number from the Professional WA plan. Pros: easiest builder here. Cons: less suited to open questions. See Landbot alternatives.

Chatbase

Best for: an agent that answers from your documents with little design work. Hobby is $40 a month ($32 yearly) for 700 message credits; voice and API access come on Standard at $150 ($120 yearly). Pros: fast, model choice. Cons: no free plan, credit-based billing.

ReplyKit

Best for: small businesses answering WhatsApp and website enquiries and booking appointments. $29, $49 or $99 a month with 1,000 to 20,000 AI replies included. Pros: no design work, booking and leads built in. Cons: no voice, no custom flows, no API.

Voiceflow alternatives for voice agents, with a 1,000-minute cost example

Voice platforms charge by the minute, combining their own fee with the cost of speech recognition, the AI model, the voice and telephony. That makes them easy to start and easy to underestimate.

Vapi

Pay as you go at $0.05 a minute for Vapi hosting, with model and voice providers passed through at cost, and $5 of free credit to start. Optional support packages start at $29 a month. Best for developers who want to choose every component.

Retell AI

Pay as you go from $0.07 to $0.31 a minute depending on the model, voice and add-ons, with $10 of free credit and 20 concurrent calls included. Calls are billed to the second, and Retell lists Twilio telephony for US calls at $0.015 a minute on top. Best for teams that want a simpler all-in rate.

Here is what 1,000 minutes of calls a month costs on each, using the vendors' own published examples:

Put that against your call volume. A hypothetical clinic taking 20 calls a day at three minutes each uses about 1,800 minutes in a 30-day month, so roughly double the figures above. And someone still has to design, test and maintain the voice agent. For many small businesses, the cheaper fix for missed calls is getting callers onto a written channel; we compare options in missed-call text back versus a WhatsApp AI agent.

Free and open-source Voiceflow alternatives

If "free" is the priority, you have three realistic routes, each with a catch.

1. Dify Community edition. Free to self-host, with visual workflows and knowledge retrieval. Its licence is a modified Apache 2.0 that forbids running it as a multi-tenant service or removing its front-end logo without a commercial licence. Its cloud Sandbox is free with 200 message credits.
2. Rasa Developer Edition. A free licence for up to 1,000 external conversations a month and one bot, usable in production. Rasa Open Source (Apache 2.0) is in maintenance mode.
3. Botpress Free. Hosted, 100 conversations a month, no server to run.

One project to avoid for new builds: Flowise, which was archived in August 2026 when its team wound down. Open source cuts the platform fee; you still pay for hosting, AI usage and the hours to build and maintain it.

Where ReplyKit fits, and when a voice platform is the better buy

ReplyKit is the alternative for a small business that came to Voiceflow wanting customer messages answered, not a design project. It answers WhatsApp and website chat from your website, PDFs, price lists and Q&A pairs, understands voice notes and photos, captures name, need, budget and timing, and books real open slots with a reminder about 24 hours before. You take over any chat in one click. See the plans.

WhatsApp connects by Quick Connect, scanning a QR code to link your number as a device in about two minutes. It is unofficial, not the WhatsApp Business API, and a number can be restricted. You see one plain notice, and pressing Connect accepts section 3 of our Terms. AI replies are capped per number (30 an hour and 200 a day by default), and we recommend a dedicated number.

Choose Vapi, Retell AI or Chatbase's voice plans if your customers phone rather than message: ReplyKit does not answer phone calls, send SMS or do missed-call text back. Choose Botpress or Dify if you build agents for clients or need custom integrations. If WhatsApp is your front door, try ReplyKit free for 7 days.
