Get started

Trace your first call

Get your first trace in Respan in 5 minutes.

1. Sign up

If you don’t have a Respan account, sign up for free at platform.respan.ai.

2. Instrument your app

In your project directory, run the Respan CLI setup script:

$npx @respan/cli setup

The CLI uses your preferred coding agent (Claude Code, Cursor, Codex, etc.) to detect your project language, install the Respan SDK, and instrument your code. If you don’t have a Respan API key set in your environment, it creates one for you and prints an export RESPAN_API_KEY=<key> command to run in your shell.

3. View traces

Once instrumented, your app logs traces to Respan for every AI call.

Or try it live without installing anything.
