Best for

Agencies and SMB-to-mid-market teams that want a packaged builder rather than a developer API, especially those already on HubSpot or GoHighLevel.

Editor verdict

Solid no-code option with credible compliance posture and the integrations a small services business actually uses. Pricing is usage-based ('pay only for calls and chats conducted') but specific rates aren't published, so budget modeling needs a call.
