NovaSynth by Noveum

NovaSynth by Noveum is a self-service voice AI agent testing platform for developers and QA teams. Create AI caller personas and scenarios, place single or batch test calls to an authorized phone or LiveKit endpoint, and inspect recordings, transcripts and evaluations. Test interruptions, background noise and conversation flows, then rerun scenarios to detect regressions before deployment. An account and a reachable, configured agent endpoint are required. The freemium plan includes 2,500 shared credits per month; voice calls use 100 credits per minute and evaluations may consume additional credits. Pro starts at $69 per month.
