Coval
Test and monitor customer-facing voice agents through simulation, production evaluations, human review, and CI workflows.
About Coval
Coval brings voice-agent simulation, production monitoring, human review, and observability into one evaluation workflow. Teams can define checks for identity verification, escalation, hallucination, difficult callers, and policy rules, then run those checks before release or against production conversations. Engineering teams can connect through API, CLI, MCP, skills, SDK, or webhooks. Evaluations can run in CI, where pass rates can gate a deployment. When a run fails, transcripts, audio, and turn-by-turn traces help teams locate the problem. Coval also supports multi-customer agent programs through tailored test suites and exportable reliability evidence. Starter costs $100 per month after a seven-day trial. Higher tiers increase simulation and monitoring capacity, extend trace retention, and add governance, support, and deployment controls.
Best for
Best use cases
Testing agent behavior before launch
Monitoring production calls at defined monthly volumes
Running evaluation workflows through API, CLI, MCP, or skills
Compare before choosing
Starter limits simulation to 100 minutes and monitoring to 1,000 calls monthly
Growth raises capacity to 1,000 simulation minutes and 10,000 monitored calls monthly
Enterprise adds negotiated capacity, private deployment, SSO, and custom SLA options
Features
Pre-release regression testing
Run behavioral scenarios before launch and gate deployments when an agent fails defined checks.
Production call monitoring
Score monitored conversations and review traces to find quality, policy, or compliance failures.
Multi-customer agent QA
Maintain customer-specific test suites and rerun them when shared prompts, models, or flows change.
Pros
- Starter includes unlimited seats, which avoids per-user cost for a small evaluation team.
- API, CLI, MCP, and skills are included across plans, so teams can fit evaluations into existing workflows.
- Every listed plan includes HIPAA, SOC 2 Type II, and GDPR coverage for regulated adoption needs.
Cons
- There is no listed free plan; Starter costs $100 per month after the seven-day credit-card trial.
- Starter is capped at 100 simulation minutes and 1,000 monitored calls per month, which may constrain active production programs.
- Private or VPC deployment, SAML SSO, SCIM, and custom data controls require the Enterprise plan starting at $4,500 per month.
