In-House Builders
You own the stack — LiveKit, Pipecat, or your own orchestration layer. You don’t need another platform to build on; you need evals that plug into the pipeline you already have and tell you when something breaks.
Building in-house means you own quality. The frameworks that move audio don’t tell you whether the agent verified identity, escalated correctly, or made something up.
Coval is the evaluation layer that sits on top of whatever you’ve built. It exercises your agent end to end, scores it against the behaviors you define, and fits into CI so reliability keeps pace with how fast you ship.
LiveKit, Pipecat, your own orchestration layer — connect over API, SDK, or webhook. Coval drives your agent the way a real caller would, no rip-and-replace.
Run scenarios on every commit and pull request. Gate deploys on pass rates and catch regressions before they reach production — the same way you test the rest of your code.
Every run gives you the transcript, the audio, and the turn-by-turn breakdown — so when a scenario fails, you know exactly where the agent went wrong.
Agent Behaviors
Identity, escalation, hallucination, frustrated callers, and more — codify the behaviors your agent must get right, and run them as tests on every commit.
