Kindred helps you register and validate AI agents, search and inspect their traces, and run reproducibility tests.

​
What you can do

  • Instrument your agent — Add the Kindred tracer (Node or Python) so LLM and tool calls are logged automatically.
  • Get an API key — Sign in to the web dashboard and copy your API key from Settings for use with the tracer.
  • Use the replay URL — Run reproducibility tests by pointing Kindred at your agent’s replay endpoint and re-running sessions.

​
Docs overview

Setup Kindred tracer

Install and configure the Node or Python tracer so your agent sends logs to Kindred.

Use the replay URL

Configure the Target URL (replay_url) and run reproducibility tests from the dashboard.

​
Next steps

  1. Set up the Kindred tracer in your agent project.
  2. Get your API key from the web dashboard and set KINDRED_API_KEY.
  3. When you’re ready to test determinism, configure and use the replay URL.
