Building on Vapi means you can ship production-grade voice agents in days. But shipping fast doesn’t mean skipping tests.
That’s why we’re teaming up with Coval to make evaluation as easy as deployment. You can now simulate and stress-test Vapi workflows with Coval before sending a single real call into production.
The Problem
Building a voice agent is no longer the bottleneck. What slows teams down is everything that comes after: testing flows, reproducing edge cases, keeping things stable as you scale.
Besides needing to know if the agent responds. You also need to know:
- How it handles interruptions
- Whether the flow logic holds up across edge cases
- If latency or regressions creep in between versions
Doing that manually doesn’t scale and doing it after means users complain it is too late.
What's the partnership with Coval?
If you’re building on Vapi, you can now:
- Use Coval to run automated tests across your Vapi workflows
- Track latency, task completion, and flow accuracy across agents
- Catch regressions before they impact live traffic
This lets you run end-to-end tests on the same stack you deploy.
