CEL playground

Try out CEL expressions interactively in the agentgateway admin UI.

You can try out CEL expressions directly in the built-in CEL playground in the agentgateway admin UI. The playground uses agentgateway’s actual CEL runtime, so custom functions and variables specific to agentgateway are available for testing.

To open the playground:

1. Run agentgateway.

   agentgateway -f config.yaml

2. Open the CEL playground.

3. In the Expression box, enter the CEL expression that you want to test.

4. In the Input Data (YAML) box, paste the YAML file structure that the CEL expression is running against.

5. To test your CEL expression, click Evaluate.
