The honest brief
Coval
Brings autonomous-vehicle-style simulation testing to voice agents — turns a few test cases into thousands of scenarios and scores live calls.
- Generates realistic scenarios from few cases
- Tests both voice and chat agents
- Production call monitoring + scoring
- Runs over text and live phone calls
- No free tier — 7-day trial only
- Starts at $100/month
- Focused narrowly on conversational agents
- Younger than general LLM eval tools
Patronus AI
Ships trained evaluator models (Lynx, GLIDER, Percival) rather than only prompt-based LLM-judge scoring.
- Research-backed Lynx, GLIDER, and Percival models
- Covers hallucination, judging, and agent-trace debug
- Self-serve API with free credits
- Guardrails + monitoring across the lifecycle
- Cloud-only; no self-host
- Usage-based pricing can be opaque at scale
- Smaller OSS footprint than open eval tools
