Retell AI is a developer platform for building voice agents. If you just want an AI receptionist answering on your website, WebCallHub is the finished product — one script tag, no code, 3 minutes.
Retell gives developers the building blocks. WebCallHub gives you the working receptionist. It comes down to whether voice AI is your product or a feature.
WebCallHub time-to-live
Paste one script tag and the AI is answering. No flow to design, no front end to build, no infrastructure to run.
What you own on Retell
Conversation flows, model + telephony integration, the web interface, and ongoing maintenance. Maximum control, real engineering.
Predictable pricing
WebCallHub is a flat monthly plan with the whole experience included — not per-minute usage stacked on model and telephony costs.

If voice AI is your product — a custom phone agent, an outbound calling system, a call-center voicebot, or a feature embedded in your own application — Retell gives you the control to build it exactly, and you have the engineers to run it.
If a website voice agent is a feature you want live now, building it on infrastructure is the slow, expensive route. That's exactly the case WebCallHub was built for.
No developer needed. Works on any website.
