+## `checkly checks run`
+
+<Note>The `checkly checks run` command is available since CLI v8.18.0.</Note>
+
+Run deployed checks immediately using their configured locations and alerting rules. This is the CLI equivalent of selecting **Schedule now** in the Checkly dashboard.
+
+<Warning>
+These are normal monitoring runs. They update check health and can trigger configured alerts. To run checks in a test session without affecting monitoring state or sending alerts, use [`checkly trigger`](/cli/checkly-trigger).
+</Warning>
+
+**Usage:**
+
+```bash Terminal
+npx checkly checks run [options]
+```
+
+Without a selector, the command runs all eligible checks in your account. By default, it waits up to 600 seconds for every check session to finish and exits with a failing status code if a session fails, times out, or is cancelled.
+
+**Options:**
+
+| Option | Required | Description |
+|--------|----------|-------------|
+| `--tags, -t` | - | Select checks by tag. Use commas to require multiple tags, or repeat the option to match any filter. |
+| `--check-id` | - | Run specific checks by ID. Accepts comma-separated values and can be repeated. |
+| `--refresh-cache` | - | Refresh the selected checks cache before running. |
+| `--timeout` | - | Number of seconds to wait for all check sessions to finish. Default: `600`. |
+| `--detach, -d` | - | Start the check sessions and exit without waiting for results. |
+| `--[no-]fail-on-no-matching` | - | Fail when no checks match. Enabled by default. |
+| `--output, -o` | - | Output format: `table`, `json`, or `md`. Default: `table`. |
+
+### Run Examples
+
+```bash Terminal
+# Run one deployed check and wait for its result
+npx checkly checks run --check-id=<check-id>
+
+# Run checks that have both the production and api tags
+npx checkly checks run --tags=production,api
+
+# Run checks matching either tag filter
+npx checkly checks run --tags=production,api --tags=critical
+
+# Schedule matching checks and exit immediately
+npx checkly checks run --tags=production --detach
+
+# Return machine-readable results
+npx checkly checks run --check-id=<check-id> --output=json
+
+# Exit successfully when no checks match
+npx checkly checks run --tags=optional --no-fail-on-no-matching
+```
+
+The `--timeout` option only controls how long the CLI waits. Check sessions continue running in Checkly after the CLI times out. Use `--detach` when you do not need to wait for results.
+
