SimpleSSM v1.1 was just released. This version introduces Send Command, making it possible to run a single command across multiple instances at once. What used to take repetitive logins and manual execution can now be done in one step, with results returned per instance so you can quickly spot any issues.

It is built on top of AWS Systems Manager, so it fits cleanly into existing IAM policies and audit logging without adding new access paths.

This has been one of the most requested features, and it is a big step toward making routine fleet management faster and less error-prone.
