Callsy vs Vapi. A developer platform to build voice agents vs a done-for-you e-commerce agent.
Vapi is a developer platform for building, testing, and deploying voice AI agents. It's powerful and flexible if you have engineers who want to assemble a custom agent from models, telephony, and code, with usage-based pricing. Callsy is the opposite trade-off: a packaged, done-for-you AI voice agent for e-commerce that recovers carts and answers calls out of the box, no building required, EU-native and live in minutes. If you have a dev team and want to build a bespoke agent, Vapi fits. If you want e-commerce results without engineering, that's Callsy.

Domande frequenti
Is Callsy built on a platform like Vapi?
Callsy is a finished product, not a builder. Vapi gives developers the pieces to assemble a voice agent; Callsy ships a ready-made e-commerce agent you connect to your store. You get outcomes, recovered carts and answered calls, without engineering.
Vapi looks cheaper per minute. Is it really?
Vapi's per-minute rate is infrastructure only. Once you add the LLM, telephony, build time, and ongoing maintenance, the real blended cost and effort are much higher. Callsy's flat pricing includes the whole working product, so there's nothing to assemble or maintain.
Do I need developers to use Callsy?
No. That's the core difference. Callsy is configured, not coded, and is live in minutes. Vapi is designed for teams who want to build their own agent.
