Vapi Alternative: Building Custom Voice Agents Faster

Why Switch from Vapi?

Vapi has done a commendable job lowering the barrier to entry for voice agents. But as developers scale, they often hit 'the complexity wall'—the point where managing custom tools, webhooks, and advanced context windows becomes rigid and frustrating.

A Superior Developer Experience

Speaksync provides a transparent, headless architecture. We don't try to lock you into our prompt management system. Instead, we offer pure, highly-configurable voice pipes that connect seamlessly to your existing LLM infrastructure (be it OpenAI, Anthropic, or an open-source model).

Getting Started

Migrating takes less than an afternoon. Check out our documentation to see how you can swap out the Vapi SDK for Speaksync and immediately see a drop in latency and an increase in voice expressiveness.
