Comparing Vapi and Voiceflow? Both are AI Agents & Chatbots and Voice & Phone AI tools in the directory, which is why buyers put them on the same shortlist. Below is a side-by-side look at how they price, what they integrate with, and when each is the better fit, so you can pick on the facts rather than either vendor's own sales page.

Vapi is a developer platform for voice AI agents. Rather than selling a finished support bot, it sells the orchestration layer: an API and SDKs that wire together speech-to-text (Deepgram and others), any major LLM (OpenAI, Anthropic), text-to-speech (ElevenLabs, PlayHT, Cartesia), and telephony (Twilio, Vonage, Telnyx) into a low latency phone agent. Support teams meet Vapi indirectly, as the engine behind custom-built inbound support lines, appointment desks, and agencies' white label voice products.
Founders Jordan Dearsley and Nikhil Gupta went through Y Combinator in 2021 with a productivity app called Superpowered, then pivoted to voice infrastructure in 2023 after Dearsley built himself an AI phone bot to think out loud with. It worked: Vapi reports over a million developers and a billion calls handled. It raised a $20 million Series A led by Bessemer in December 2024, then a $50 million Series B in May 2026 at a $500 million valuation, roughly $72 million total. Amazon chose Vapi for its Ring division after evaluating over 40 rivals.
Pricing starts at $0.05 per minute for the platform itself, with SMS at $0.005 per message. Provider costs (speech, LLM, voice, telephony) are passed through at cost, or drop to zero if you bring your own API keys. Realistic all in costs run $0.07 to $0.25 per minute. Ten concurrent calls are included, extra lines cost $10 monthly, and compliance add-ons are priced like enterprise software: HIPAA at $2,000 monthly, zero data retention at $1,000 monthly.
Choose Vapi if you have engineers and want maximum control over every layer of a support voice agent, with the freedom to swap providers as models improve. Skip it if nobody on your team writes code, or you want a vendor accountable for resolution rates rather than infrastructure.

Voiceflow is a visual platform for designing, testing, and shipping AI agents across chat and voice. Teams build conversation logic on a collaborative canvas, ground agents in knowledge bases, and deploy to web chat, phone lines via Twilio, and messaging channels. For support work specifically, native integrations let an agent create and update Zendesk tickets, touch Salesforce records, or cancel a Shopify order mid conversation, and anything else is reachable through REST APIs, custom functions, and MCP.
The company was founded in Toronto in 2019, led by CEO Braden Ream, and grew from conversation design tooling into a full agent platform. It has raised $35 million, most recently a $15 million round from OpenView in August 2023 at a $105 million valuation, following a 2021 round led by Felicis. Its own announcements cite more than 130,000 users and customers including The Home Depot, US Bank, BMW, Vodafone, State Farm, and JP Morgan.
Pricing moved to a credit system in April 2025. Third party trackers list a free starter tier, Pro from $60 monthly with 10,000 credits, Business from $150 monthly, and custom Enterprise, with extra editor seats at $50 each. Credits are consumed by every message, call, and model invocation, and reports say agents stop responding when credits run out mid cycle. Note that Voiceflow's own pricing page now steers business buyers toward a sales conversation, so treat published tiers as a floor.
Choose Voiceflow if a mixed team of designers, support leads, and developers needs to own agent behavior together, and you want one canvas covering both chat and voice. Look elsewhere if you want pure per minute phone economics (Retell, Vapi) or a fully managed enterprise deployment; and budget carefully, since seats plus credits add up faster than the sticker price suggests.
