Your agents silently fail in production
We fix that

Agents hallucinate, loop, and fail silently in production. Maev surfaces every failure automatically in real time.

Not just logs. A failure detection layer built for AI agents.

What's actually happening

Your agent is already broken.
You just can't see it.

These aren't edge cases. They're happening right now, in your production agent, with zero visibility.

HIGHHallucination
SILENT

Agent returned fabricated API data. User filed a support ticket 3 days later.

CRITICALInfinite loop
COST

Tool call triggered itself 47 times. $180 burned before rate limit hit.

HIGHTool call error
SILENT

External API returned 429. Agent retried 12 times silently. No alert fired.

MEDIUMContext exhaustion
SILENT

Prompt hit 128k tokens. Agent silently dropped memory. Output was wrong.

CRITICALCost explosion
COST

$340 burned in 8 minutes on one runaway session. Caught on the billing page.

MEDIUMGoal drift
SILENT

Agent completed the wrong subtask. Returned success. No one noticed for a week.

Maev detects all 10 failure categories automatically. Zero config.

The difference

Shipping blind
vs. knowing exactly what broke.

Without Maev
  • Failures surface as user complaints, days later
  • No logs, no traces, no context to debug with
  • grep through stdout hoping to find something
  • Cost spikes show up on the billing page
  • Infinite loops run until rate limits stop them
  • No idea which run failed, when, or why
With Maev
  • Every failure classified before users ever see it
  • Full trace: every LLM call, tool use, and decision
  • Replay any run step by step in the dashboard
  • Cost per run, broken down by step
  • Loops caught and alerted within seconds
  • Root cause surfaced in seconds, not hours

Smart alerting

Slack or email alerts the moment something breaks, with the failure category already attached.

< 5ms overhead

All telemetry is async and fire-and-forget. Your agent thread never waits for observability.

Performance

Data ships out of band. Your agent never waits for observability.

Built on OpenTelemetry, the industry standard for distributed tracing, with a purpose-built layer for AI agent observability.

Cost control

Stop paying for
agent waste

Most cost overruns come from loops, duplicate calls, and runaway context. Maev finds them before your billing page does.
