Vapi is a developer platform for building voice AI — powerful, and a project to match. If you just want an AI receptionist live on your website, WebCallHub is the finished product: one script tag, no code, 3 minutes.
Vapi gives you the pieces. WebCallHub gives you the working product. The right choice depends on whether voice AI is your product or a feature.
WebCallHub time-to-live
Paste one script tag and the AI receptionist is answering. No pipeline to wire, no front-end to build, no servers to run.
What you assemble on Vapi
Assistant logic, LLM, speech-to-text, text-to-speech, a web widget, and hosting — then maintenance. Great control, real engineering.
Predictable pricing
WebCallHub is a flat monthly plan with the whole experience included — not per-minute usage plus model and telephony costs.

If voice AI is your product — a custom phone agent, an outbound calling system, a complex multi-step voicebot, or a feature deep inside your own app — Vapi gives you the control and flexibility to build exactly what you need, 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 path. That's the case WebCallHub is built for.
The per-minute API price is the small part. Designing the assistant, building the widget, and wiring booking + handoff is weeks of developer time you don't get back.
Per-minute platform fees plus the LLM, speech-to-text, text-to-speech, and telephony underneath. Predicting a monthly bill takes a spreadsheet.
Models change, prompts drift, edge cases appear. A built system is a system you own forever. WebCallHub is maintained for you.
No developer needed. Works on any website.
Copy a single script tag into your site. WordPress, Shopify, Wix, Squarespace, or plain HTML — all work.
Point it at your website and it trains on your services, pricing, and FAQ. Answers questions and books appointments — no prompt engineering.
Every conversation is transcribed, summarized, and sent to your team, with a human-handoff path when it matters.
