What we know about Voiceflow
Voiceflow is a voice ai platform: agent builder (chat + voice). This profile tracks what we have verified about Voiceflow, each fact linked to a primary source and dated.
On pricing, Voiceflow starts at $0.05 per minute for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes. Every Voiceflow comparison on the site works from that all-in figure rather than the headline number, because the headline number is rarely what the invoice says.
New Voiceflow accounts get Free trial, no credit card required to test with before a card is required, which is enough to run a handful of real calls and judge latency and voice quality for your own script rather than a demo.
On capabilities, Voiceflow covers bring-your-own llm, native outbound campaigns, built-in knowledge base, soc 2 type ii, gdpr tooling / eu residency, and no-code agent builder, and does not offer annual contract required for best pricing?. Each of those is verified against Voiceflow's own docs or dashboard, not marketing copy.
On performance, Voiceflow reports 5 concurrent calls on the base plan. Latency figures are vendor claims until we measure them ourselves, and they are labeled that way on the Voiceflow fact sheet, so treat them as a starting point rather than a guarantee.
For compliance, with Voiceflow: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Voiceflow before you commit, since these change plan by plan.
In total we track 18 verified facts for Voiceflow today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the Voiceflow fact sheet below, and each row links the primary source it came from so you can check our work.
Whether Voiceflow is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how Voiceflow actually fares against the platforms buyers most often weigh it against.
