Voiceflow
6.7/10Voiceflow is a visual platform for designing, testing, and deploying AI chat and voice agents for customer experience teams and agencies.
Data last updated November 2026 · Our methodology
Overview
Voiceflow is a collaborative builder for AI agents that handle customer conversations over web chat, API, and phone. Teams design agent logic on a drag-and-drop canvas, pick a different LLM for each step from providers such as OpenAI and Anthropic, and ground answers in a knowledge base with tag filtering and source attribution. Developers can add sandboxed JavaScript functions, call the REST API and webhooks, and use a CLI. Version history with diffs and rollback, and separate development, staging, and production environments, support teams that work together on agents. Voice calls run through Twilio, Vonage, Telnyx, or a number provisioned by Voiceflow, with Deepgram or Google for speech recognition and ElevenLabs, Amazon Polly, or Google for speech output. The platform fits CX teams in mid-sized and large companies, and agencies that build agents for clients. Agencies get multi-client workspaces and white-labeling. Pricing combines a monthly plan fee, editor seats, and usage credits. Free gives a one-time credit grant that does not renew. Pro and Business plans include a monthly credit allotment, and Enterprise is custom. The public pricing page now asks buyers to request pricing. Third-party sources cite Pro from about $60 a month and Business from about $150 a month. A chat message costs about 1 credit and a phone minute about 10, with LLM tokens charged on top. Extra editor seats have been about $50 each. The main drawback is cost predictability: several meters drain credits, voice calls are expensive, and agents stop responding when credits run out. CRM and business-tool connections also depend largely on the API and webhooks rather than native connectors.
Our Rating
Who Voiceflow is best for
Good fit
Voiceflow offers a dedicated agency offering with multi-client workspaces, white-labeling, and usage billing.
Enterprise buyers get SSO, audit logging, SOC 2 Type II and ISO 27001 compliance, staged environments, and custom contracts.
The Business plan targets CX teams that need roles, observability, and both voice and chat channels.
Less suited
Pro is affordable to start, but credit consumption can grow quickly with usage.
It can be used for simple support bots, but the learning curve and metered pricing are heavier than simpler chatbot tools.
Pros & Cons
Pros
- The drag-and-drop canvas, with per-step model selection, gives fine control over agent logic. It holds a 4.6 out of 5 rating on G2.
- Version history with diffs and rollback, plus dev, staging, and production environments, suits teams that build collaboratively.
- Developers can extend agents with JavaScript functions, a REST API, webhooks, and a CLI.
- Agencies can manage multiple client workspaces, white-label agents, and hand them off to clients.
- The security page lists SOC 2 Type II, ISO 27001, GDPR, and HIPAA.
Cons
- The public pricing page no longer shows prices, so buyers must request a quote or rely on third-party figures.
- Credits are drawn down by several meters, and voice minutes cost about ten times a chat message, which makes costs hard to predict.
- Agents stop replying when credits run out unless auto top-up is turned on.
- Voice depends on third-party telephony and speech providers. Reviewers say its voice quality trails voice-native platforms.
- Advanced logic has a steep learning curve, and documentation and support get mixed reviews.
