    Stop guessing
    why your agents fail

    Production monitoring for AI agents. Surface silent failures, pull context across traces, improve your agent before users churn.

    ISSUES

    Surface failures you didn't know to look for.

    Lemma audits every trace against your agent's instructions and groups recurring failures into issues.

    LIVE ALERTS

    Get notified on what matters.

    Lemma triages issues and alerts you in Slack.

    LEMMA MCP

    Fix it where you work.

    Pull context into your coding agent to resolve it without context-switching.

    METRICS

    Ship with confidence.

    After deploying the fix, Lemma creates an online eval. If a regression occurs, you'll know immediately.

    The Friday briefing on AI agent observability and reliability.

    Latest — Issue 001 ·

    Debugging production agents is moving earlier in the stack

    A coding agent that leaked secrets from repository instructions; a managed runtime that hid injected logic from customer-visible telemetry; a workflow that reported success while one of its tools had already failed. Across all three, reconstructing what happened was easier than reconstructing why.
