+## Listen mode
+
+The `--listen` flag keeps the simulator alive and re-runs it for each incoming trigger event, instead of compiling and executing once then exiting.
+
+- **HTTP triggers**: starts a local HTTP server on port `2000`. Each POST request triggers a fresh simulation run.
+- **EVM log triggers**: watches the configured chain and re-runs on each matching log event.
+
+```bash
+cre workflow simulate my-workflow --listen --target staging-settings
+```
+
+This is useful during active development — make a code change, resave, send another event, and see the result immediately without restarting the CLI. See [Testing HTTP Triggers in Simulation](/cre/guides/workflow/using-triggers/http-trigger/testing-in-simulation) for a detailed walkthrough with HTTP triggers.
+
 ## The `--broadcast` flag
 
 By default, the simulator performs a **dry run** for onchain write operations. It prepares the transaction but does not broadcast it to the blockchain.
