Strengths

Pros

  • Built specifically for agent reliability
  • Supports OpenTelemetry-compatible instrumentation
  • Publishes SOC 2 Type II and encryption controls
Considerations

Cons

  • Public pricing is not published
  • Instrumentation requires engineering work
  • Automated issue analysis still needs human review
Considerations

Limitations

Lemma can miss failures, group issues incorrectly, or expose sensitive prompts and outputs if tracing is misconfigured. Teams must control sampling, redaction, access, retention, alert thresholds, and human approval of every proposed fix.
