Vapi Voice Track
The best voice-first AI build.
The challenge
Make voice the interface. Build a product with a live Vapi voice flow at its core — agents, voice interfaces, or telephony flows.
This is Vapi's first EU hackathon partnership (~1M developers globally). Every builder gets credits to put a voice agent live during the weekend.
How you win
Judging criteria are set with Vapi and shared before the weekend.
How to stand out
- Put a real, working Vapi voice flow at the heart of the demo — not a bolt-on.
- Pick a use case where voice is genuinely the right interface, and make the conversation feel effortless.
