| Key features | - Acceptance test verification before fix deployment
- One-click revert of all changes from a failed fix attempt
| - Monitor AI agent conversations without code by connecting Langfuse or LangSmith
- Judge conversations on six criteria: accuracy, goal alignment, decision quality, completeness, helpfulness, and factuality
- Create code-based rules that block risky actions before they run
- Group failures into problems with suggested rules and failure counts
- Send Slack alerts for serious mistakes and reply checks immediately
- Add to agents with one line of Python code for OpenAI Agents SDK, LangChain and LangGraph
- Mask sensitive data like email addresses, phone numbers and card numbers before sending to Kalytera
- Rules continue running offline if Kalytera goes down
- Correct judge verdicts by marking conversations as passed or failed
|
|---|
| What makes it different | - Provides real runtime evidence to AI agents instead of requiring them to guess or generate test cases
- Runs completely locally with zero code changes needed to the codebase
- Proves fixes work by re-executing against acceptance tests the agent never sees
- Works with any AI coding agent without requiring new subscriptions or API keys
- Uses published scientific methods for each decision, with full math and attribution transparency
| - Rules are code-based, not AI, so they cannot be overridden or argued with
- No code setup using Langfuse or LangSmith connections for immediate visibility
- Rules continue protecting agents even when Kalytera is offline
- Catches exact mistakes from real AI agent incidents like database deletes, account takeovers and crypto theft
- Customer data stays on your servers; Kalytera only reads conversations, never writes or stores sensitive data
