Put two AI support products side by side, then test the differences that matter to your team: fit, channels, integrations, pricing, and operational tradeoffs.
Both products appear in ai support agents. That overlap gives you a starting point; it does not mean the products cover the same channels, workflows, or deployment model.

The table below preserves each vendor’s scope and qualifiers. An unlisted feature is unverified here; it is not a claim that the feature is unavailable.
Before buying
HubSpot Breeze: Eligible HubSpot Professional or Enterprise subscription plus shared HubSpot Credits. Required seats, subscription commitments and any onboarding depend on the chosen route. Credits are shared with other usage-based features; confirm included allowance, credit rate and overage or auto-upgrade settings. Vapi: Usage-based hosting plus provider costs for transcription, language models, speech and telephony. Bring-your-own keys move provider billing to your own account. Includes 10 concurrent calls; extra lines cost $10/month each. Scale uses a quoted platform fee and committed volume under an annual contract. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded sources for HubSpot Breeze include HubSpot knowledge base; CRM records; tickets; website content. For Vapi, they include prompts; custom functions; documents; external APIs. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: HubSpot Breeze: Customer Agent eligibility extends beyond Service Hub, but specific channels and CRM actions require configuration. Shared credit limits can pause usage or trigger additional purchased capacity under the account billing settings. Vapi: Total per-minute cost includes selected STT, LLM, TTS and telephony providers; more engineering is required than turnkey tools.
