for the 3am builders

Ship a chatbot you can sleep on.

Catch the moments your agent goes off-script — before your users do.

Your bots break differently.

Sentry tells you the API returned 200. It can't tell you the agent told a customer your refund window is 90 days when it's 14. Conversational failures are silent — they show up in support tickets, not stack traces.

How it works

  1. 1

    Connect

    Swap your provider's base_url for rendfly's. One line. OpenAI, Anthropic, Gemini, and friends.

  2. 2

    Define

    Paste your system prompt. rendfly extracts the rules automatically.

  3. 3

    Catch

    Every conversation is scored. When something drifts, you get a Slack ping before your user does.

What you get

  • Real-time scoring of every conversation

  • Slack and email alerts the second something breaks

  • Drift detection vs. your last 7-day baseline

  • PII stripped before storage
