Jelliu vs Vapi

What Vapi is great at

Vapi gives developers granular control over the voice stack — model, transcriber, and voice provider are all swappable, and you orchestrate the call flow in your own code. If you are building a bespoke voice product, embedding voice deep into your own app, or need behavior that no off-the-shelf dashboard exposes, that flexibility is the point.

The trade-off is that Vapi assumes an engineering team. There is no built-in campaign dialer, CRM, or operator dashboard — you assemble those yourself, and you own the hosting, monitoring, and iteration.

What Jelliu does differently

Jelliu is the operating layer a business actually runs on. You create an agent in a wizard, connect your channels and CRM, load contacts, and launch an outbound campaign or publish an inbound agent — without writing code. The voice is studio-grade and multilingual, and every call streams into real-time analytics with sentiment and conversion scoring.

Because campaigns, contacts, omnichannel, and reporting are first-party, a non-technical operator can go from signup to live calls in an afternoon. The same platform scales from a 3-person startup to a BPO contact center.

When to choose which

• Choose Vapi if you have developers and want to build a custom voice application with low-level control.
• Choose Jelliu if you want a non-technical team to launch, run, and measure AI agents across voice and messaging without engineering.
• Choose Jelliu if you need outbound campaigns, a CRM, and omnichannel in one place rather than assembled from parts.
